"Yes, madam." And then she explained to you about how to hold the baby properly, when lactation starts, and what medication to take, considering you hadn't taken any extra supplies throughout this unknown pregnancy.

It's a surprise this little green thing could survive and thrive in your body, stealing your food without you knowing. He's going to grow up to be a piece of sh— genius in the future, totally. Without much thought, you asked the nurse for your belongings, and she gave them to you after escorting you to your ward with other mothers.

You take out your phone and snap a picture of the lil green thing.

You thought about it for a while. What should you name your lil green baby? He's green and steals. Steal and green… maybe a snake-like name? What about Sneku? Uh, yeah, let's go with this one. You typed his name and accidentally made a typo; yet as you're about to edit it, he sends out his replies.

Wow. His comments surprised you. Does he know? He's one dense man, so you doubted that. But then again, you two are— well, active, and wouldn't stop rutting like a bunny in heat; so it's not that shocking for you to be in this situation.

So, what shall you do to soft launch this news to him without overwhelming the man?

Sighing softly, you adjusted the baby's position on your chest to align with the camera's angle, capturing both him and you in the frame.

Snap!

Incoming video call...

Here comes the chaos.

You tapped the green button, and his face pops into view. Eyes wide, mouth agape.

"Hey—"

"What happened?! Are you okay? Why, wh— why are you with a baby?!" Byakuya stumbled on his words, face so dang close to the phone. You could hardly see anything but his forehead on the screen.

Instead of answering him, you showed little Sneku — Senku, now — to him. The little green thing is breathing softly on top of you, fist clenched, lips slightly parted. His eyes are closed, but it somewhat looks open. Active sleep, perhaps.

Byakuya's continuous questions ended as he looked at the infant. So tiny… His eyes welled up at the sight. His mind is working so hard to understand the situation. Does this mean you've been pregnant all this time without him noticing? How could he? You're his wife, and he should've noticed it long ago!

Don't tell him… you went through labour alone?!

Droplets of tears fell from his eyes as guilt consumed his entire being. He wondered how scared you must be to walk through such a traumatising experience by yourself while he's over here, chatting about a physics lecture with his students.

"I… I'm sorry, love. I should've been there for you." He sobbed as he sniffed back the snot flowing out of his nose. "You looked exhausted."

"I am." You smiled lightly, trying to lighten up the mood. The man looked terrified at your answer, though. Maybe you should've said something different. Huh.

"I-I-I'll be there in an hour. I'll have my colleagues handle the field trip. Just— just stay there. Don't move, okay?" With that, the call ended, and it's just you and Senku once again.

Well, that went better than you expected. Not much shouting or almost passing out. Maybe you were overexpecting his surprise. Can't say you're not a tiny bit disappointed.

"Let's go." Your brother, Stanley, called from a higher branch. The man then jumped without much hesitation. He landed on his feet before walking away without even bothering to wait for you.

"Wait, I'm comin'—" You were about to do the same as he did, but thanks to your lack of experience, your feet slipped, and you fell from the branch. You didn't have the chance to scream in shock when massive leaves slapped your face multiple times as you descended. Soon, you passed out from the impact.

"Please wake up! Please wake up!"

You heard Luna's voice as she prayed right next to your ear. Opening your eyes, you were met with more than five pairs of staring eyes — mostly unfamiliar faces. What happened?

"You're awake! Oh, thank goodness. I'm so glad you didn't die yet. Quick, we need your help!" She tugged on your arm, lifting you from the bed and pulling you into a room, callous to your injury. Inside lay an unconscious man, covered in bandages and dried blood stains.

"We need to remove the bullets. Please save him, Doc!"

What the hell. Luna did NOT just tell these people about your incomplete medical degree. Has she lost her mind? You literally were only in your third year and have yet to complete your clinical rotation in surgery. What makes her think you could save this guy when she also can't? You two are literally on the same level, since both of you agreed to go to a med school just to find a genius partner.

"I will assist you during the procedure." A butler stood in front of you, bowing slightly in respect. Left with no choice, you nod your head and hope for the best, considering that your image is on the line.

Wait a second, didn't you just kill someone on this boat? And uh… huh. Eh, something doesn't feel right. Maybe you hit your head pretty hard during the fall and could not comprehend why you feel like saving this leek-haired man is against Dr Xeno's command. Either way, you need to get those bullets out of him first.

"Let's proceed."

Two days have passed since you treated the man's wound. Others who are on the boat had gone to who knows where; perhaps they were on a mission to probably meet your brother's boss. Either way, your job here is done, and it's time to find a way to return home safely after the hell you've gone through. Dr Xeno will surely scold your arse off for disappearing for days without notice.

The truth was, after sealing the wounds on the leek man's chest — who you learned was named Senku — a lioness-lady accidentally knocked a jar of water to your head. The hit was so strong that your life flashed before your eyes for a brief moment. Yet thanks to that, you remembered that you were supposed to let the man die per Dr Xeno's instruction.

Never mind the past. It's not like you could return and waltz your way into the building without getting a limb or two cut off by your honourable brother. He's one scary lung-dead man, after all.

"You could've used this chance to finish me off, you know?"

You heard him mutter weakly, coughing into his palm. This man couldn't be serious, could he? You weren't going to waste your hours of surgery credit to save his life, just to kill him days later. He's quite dumb for a scientist.

"Huh, I wonder why I didn't?" You replied, voice laced with sarcasm.

He chuckled, sighing softly. "While we're talking, I heard from Luna that you wanted to date me?"

What the hell did she tell him? Date. Him? Your target? What does she think this is? A fanfic? You have no idea how much of your name she had picked to save herself while you were away. If you ever get your hands on her, you're going to poke your fingers into her nostrils.

"I'm afraid your injuries are making you spout nonsense. I will let this one slide, as long as you don't bring it up again."

"Join us."

"Pardon?" Aww, hell nah. You'd rather go home (the base) and be forced to soak yourself in a bucket of ice as punishment than have your head cut off by your brother. This is a "step on shit or eat shit" type of choice.

"Join us, the Kingdom of Science. There's a place for you here."

And somehow, you ended up joining the team, which means you had to go against your brother and his man. It was a risky move; high risk, no reward, they said. But hey, that was years ago. So much time had passed since then, and who would have thought that you could go from going against your brother in a bloodied war to helping Dr Xeno make a munching cigarette for him to enjoy in space.

Sitting quietly at the edge of the cliff, your gaze falls onto the tiny, long dots of humanity going about their days. How long has it been since the first petrification? You wondered how different things would be for you if the event had never happened.

"Smiling to yourself again?"

A voice pulled you out of your reverie. You turned your head to see Senku taking his seat next to you, his feet dangling off the cliff. One push and the future of science—

"Yuzuriha is calling you for a dress fitting. You are not here because you were running away, are you?" The man teased as he nudged your shoulder with his elbow. A smirk decorated his handsome face.

"Do I really have to go?" You sighed softly, standing up as he pulled you up with him. He held your hand, guiding you to the designer's building. You quietly followed his steps.

Senku chuckled under his breath, "Come on now, it's our wedding. Your reminiscing can wait."

"But dear Senku, aren't you worried you might be left behind in survivability progress?" Gen hummed, stirring his tea with a spoon, letting the warmth dissipate into the air. After a few seconds, he lifted the cup and took a small sip, delighted with the sweet floral taste. He should get more of this variation.

Senku scoffed at that. What is the mentalist trying to say here? Survivability progress, really? "Your point is?"

"Chrome and Ruri are about to welcome their second child, and even Xeno has adopted more than 6. Not to mention Ryusui with his third, while you…" Gen smiled slightly, tilting his head in a pretence mock. "You know, single and available." He took another sip of his tea, perfectly warm and lovely.

Chrome, who was turned down earlier, puffed his chest proudly, thanking Gen for backing him up. He's a happy man, especially at the mention of his wife. He could name all the things he loved about her, and it would probably end after a few weeks of nonstop yap. To be loved is to be seen, they said.

"It was never a competition, mentalist. Besides, I have far more important things to worry about than to dabble in a love quarry." He retorted. Quickly finishing his bento to get his butt to work as soon as possible. He had a list of stuff that needed to be done before evening, and couldn't afford to waste his time on idle chatter.

The lunch continued with Gen adding some workplace gossip, while Chrome would tell about his struggle in handling his family, with Ruri being extra clingy at home. Meanwhile, Senku would occasionally nod his head and mutter a few yeses and mock reassurances here and there. Once everyone had finished their food, the three went to their separate sections of the lab.

The day blends into calculations, meetings, and 10 minutes nap every few hours. Senku may be a great scientist, but he is also a human; that means he was not excluded from normal human needs such as food, rest and perhaps even desire. And as if the world is on his side, he received a call from a certain someone not so far from his workplace. He holds the mobile in one hand while the other is busy calibrating the titration curve.

"You're not resting? It's your evening nap hour, isn't it?"

He shoots, no warm greetings whatsoever. Well, he doesn't need to; those questions alone are warm enough for you. He could hear your amused giggle at the end of the line, so he smiled at that. The sound of you laughing somehow soothes him. He sets down the apparatus to shift his focus to you completely. It's not like he could calculate with his mind in the cloud.

"I tried, but your daughter won't stop kicking." You huffed, partially annoyed, but your hand unconsciously moved to gently rub your growing belly. The due date is around the corner, and you're no different from Pinocchio if you said you're not afraid; your nose would surely grow a meter at every word spoken.

"She has been particularly active these days, hasn't she?" He hummed, checking the watch on his wrist. It's almost time to punch out. He picks all the important documents and keeps them in the drawer before sliding his bag around his shoulder. "I'll be home in 20 minutes. Crave anything?"

You thought about his question for a moment. You're not particularly hungry, nor are you full either. This is hard. "Maybe something light? Preferably from the Nanami's. Their chef made the best food." You added. After another quick convo, he ended the call to leave the building. The drive home was quiet, save for the car wheezing like an old man at every bumper.

Senku stops by Nanami's and gets himself — well, gets you — an ice cream and hash browns. Thankfully, he doesn't bump into the owner, or else he might invite him for a drink, and he would definitely need to decline the man's offer. Ryusui was never the type to back out easily. With the food in hand, he returned to the car and proceeded to drive home.

Right turn, left turn, a roundabout, a highway, left turn, and finally, he's home. He parked the car and went inside using a key he had duplicated months ago. You always told him to just let you open the door for him, but he insisted on having his own key, so that you don't have to get up from wherever you are in the house just to open the door for him.

"You're home." You waddled to him from the kitchen, a mug of chrysanthemum tea in hand. He takes off his shoes and coat, then hang it by the door before approaching your slow figure. He engulfed you in a hug, to which you were about to return when the baby kicked again. "Ah!"

He let go of you after hearing your pained wince. "Has this been going on all day?" He holds your face in his hand, as you nod.

He handed over the paper bag of food to you to get on his knees. He then patted your belly with his hand, "You got one hell of a kick, kid. Don't bully your mother too much. That's my job." He chuckles to himself.

You pout. What a meanie. Unbothered by the consequences, you tug his hair in rebellion. If he's going to play devil tonight, who are you not to fight back? You're no saint, and he knows that. Should've thought this through when he decided to come inside months ago. Whose fault was it? His, obviously. Plus, you were at the laboratory to work under Xeno once again, not to mother this man's child.

But that was long ago, and he thankfully owned up to it and courted you not long after the incident. Some may wonder: how the hell did Xeno's junior from before the petrification even end up with THE Senku Ishigami? Well, you two met at one of the conferences and were paired for a research project. Yada yada, since millennials had passed while you were petrified, the younger man somehow went from Byakuya's adoptive son to your senior. Such unfairness.

Not like you have ever bothered to know either guy before the Medusa event. The name Ishigami was never in your dictionary until he pounded into you on the lab table that night. Uh, crazy lore.

"You want it?" He suddenly asked, way too nonchalant to your liking.

The thing was, you two hadn't been active since the pregnancy due to his worrying that he might strain you further. For someone who had never cared about anyone — especially during manual labour — he is somewhat gentler when it comes to you. But it's not like you don't want to do it; rather, he had just come home from an 11-hour shift, and he surely needs a rest after such a long day.

You scrunch your face at his question, and he blinks at your reaction. Did he say something wrong? The two of you made it clear that hair tugging means sex, so why act disgusted now?

"What?" He stood up, arms wrapped around your waist. "Besides, it offers benefits. An intercourse could help reduce the potential of going past 37 weeks—"

You shut him up with a kiss. There it is, no more science talk. Senku melts instantly and holds the back of your neck while the other remain on your back. Now he went tongue-to-tongue, fighting for dominance. Just because he always lets you have your way doesn't mean he'll give up easily, especially now. So he guides you slowly until your back hits the dining table, then with that twig strength, he lifts you to sit on the table surface as he takes his space between your legs.

Deliberately, his fingers crawl their way under your nightgown until his forefinger reaches your undergarment. You hummed softly between the kisses, urging him to go further. He smiled against your lips and bite it, earning himself a gasp from you.

"Ouch… you're mean." You whined, pulling away from the kiss. He chuckles under his breath, going in for another kiss when suddenly, his phone vibrates from inside his work bag. You turned your head to the sound coming from the living room. "You're not going to answer it?"

He sighed and let go of you before striding to get his phone. Who could possibly call him right after work? He made it clear that no work call is allowed after he punched out, especially on the day before the weekend. Without much thought, he answered it.

"Ishigami's here."

"SENKU!!!! IT'S ME, TAIJU!! MANNN I FINALLY GOT YOUR NEW NUMBER!"

Yeah. Great, big Oaf doesn't really listen, does he? There's a reason why he changed his number, and this is one of them. No use dwelling on it now, better to get this conversation over with, quickly.

"Yo, what is it that ya need, big oaf?" He said in disinterest, pinky subconsciously picking on his ear, rubbing that one spot to calm his nerves.

"YUZU—" But then, he heard Taiju's shouting was cut off by Yuzuriha's more gentle voice.

"Hello, Senku. We are planning to do a gender reveal party in 2 weeks and were hoping you could make it. Are you free that day? Chrome said your schedule has been rather packed lately."

Senku thought about it for a moment. Your due date is approaching, and he has requested a week off for an unrevealed reason from Xeno. That unrevealed reason is being by your side to welcome your child. If he were not to attend Taiju's important day, would it rise suspicous? They were the best of friends since childhood, and to randomly not attend is definitely not a wise choice.

"I'll check it with my assistant after the weekend. No promise, though." He answered. This might be the best excuse he could come up with. Yuzuriha thanked him and ended the call. Senku rubbed his face, sighing softly. This is the con of having a secret partner.

The good thing is, he got to protect you from being surrounded by those who see him as a god for rebuilding humanity, or those who wouldn't stop obsessing over everything he did in his life. Yet, that means he needs to lie even to his closest circle. He can't have all the good parts of life, can he? Curse his bad luck.

"Is everything alright?" You called from the dining table, getting down slowly to waddle to him.

"Just Yuzuriha and Taiju. They're doing a gender reveal party soon, and I don't think I'll be attending." He holds your arms to stabilise you and guide you to sit on the nearby couch.

"Couldn't you tell them about us? I'm sure they won't do anything funny about it." You tried to assure him, but he shook his head. His hand found your belly, gently caressing it.

"I trust them, yes. But I know Taiju; he's not going to be discreet about me having a partner or being a father. Plus, I don't want to burden Yuzuriha with information that carries so much weight." He explained, pulling your head to rest on his shoulder.

"Then, how long will this be a secret?" You hummed softly, to which Senku shook his head.

"We'll let them know after our daughter is born, and once you're stable. I thought about possible post-partum depression, and planning to hire someone to care for you and the baby while I'm away for work. Though they need to go home before I return, to not cross paths." He nodded to himself, drafting his schedule in his mind.

Your finger traces his chest as he mumbles, not really listening to him. As if realising he's losing your attention, he stands up abruptly; that caught you off guard. He turned to you for a moment without saying anything before leaving to take the food he bought earlier. Then he returned to his seat next to you.

The two of you began to eat your snack. He dipped the hash brown into some chilli sauce and fed you. Second bite, dip, third bite, dip, fourth bite; but out of nowhere, he accidentally smudges some sauce on your chin. You were going to wipe it with a tissue when he leaned in and stuck his tongue out.

The wet organ then glided over your chin suggestively before he captured your lips into a slightly spicy kiss, thanks to the sauce. He held the back of your head, pulling you deeper into the kiss as his tongue mines its way into your mouth like a miner, touching every surface he could reach. He hummed into the kiss, loving the warmth of your skin.

He gently pushed your shoulder against the backseat, then he slowly slid you to your side to lie you down on the couch instead. Caging you under him as he got on all four above you. He needed to be quick with whatever he had planned, not wanting to put too much pressure on your back. Using his knee, he spread your legs apart without breaking the kiss.

He broke the kiss to take a deep breath, then dived in without giving you a chance to dominate him like you usually do. He feels like handling you today; besides, he shouldn't tire you too much, so yeah.

His hands made their exploration, mapping every patch of your skin with his fingertips. It's not unfamiliar, as he had long memorised every single coordinate. But every experience feels different to him, as if no matter how many times he mapped you, he'll never feel truly satisfied. Like a thirsty scientist in search of water in the middle of a desert.

With his left hand, he slid it under your sleepwear, letting it climb over the soft, bouncy hills. While his right hand continue it's dive until it reaches the first obstacle, a patch of cloth with an obvious wet spot in the middle of it. Hm, curioso?

His index finger pushed the undie open like a curtain and slid in a middle finger, followed by his ring finger. He slid them in till the base of his fingers so easily, thanks to the lubrication from the kiss alone. Who would have thought a simple kiss could get you all wet? Maybe you were sexually frustrated over the past few months of not getting anything.

The hand that was previously fondling your breasts made its escape through your collar. He gripped your chin, holding your face before pulling out of the long kiss. Trails of saliva that connected you two dripped onto your chin. He then used his thumb to smudge the fluid over your lips; a flushed smirk on his face at the sight of you so… drunk of kisses.

After seeing that you were ready, he started pulling his fingers in and out of your… pussy lips. Wet squelches filled the room as he plunged his fingers into you rhythmically while his thumb continued to rub in circles. You were squeezing him like a vice, it's tempting him to go faster, just to see how fast he could make you—

"Mhm—!"

Before you could gasp out in pleasure, he swallowed your moans with another round of kisses. Gushes of arousal fluid squirted out of you, wetting the couch, yet Senku's hand remained steadfast in its pace. Instead of slowing down, he somehow went faster, increasing his speed. His palm was basically clapping your clit like he was giving it a round of half an applause. Get it?

You squirmed, overstimulated by his fingers alone. The fact that he was relentless didn't help. You gripped his shirt, unsure of what to do with yourself. On one hand, you want him to continue, yet on the other hand, you want him to keep going, to make you feel good. Decisions, decisions.

Before Senku could pull his fingers out, another gush of fluid popped out of you, but this one is a lot thinner than your first orgasm. Confused, he inches his fingers to his nose, sniffing them. It smelled different; he had a hunch what it could be, but he couldn't confirm it without a taste test. With that, he suckled his fluid-stained fingers.

And instead of tasting like lactic acid like usual, this fluid tasted… sweet, mineral-like. His eyes widened in surprise as panic began to set in. He looked at your half-conscious state from being overstimulated and quickly adjusted your nightwear to cover you properly, and rushed to your shared bedroom to pick up your bags of clothes in case of emergencies.

After throwing the bags into the car, he went back in, picked you up and ran out of the house. If one was wondering what got him so worked up, your water just broke, thanks to his aid. Orgasms truly are the best support when it comes to labour, aren't they?

In the morning of the next day, Yuzuriha and Taiju were going home from a prenatal check when they saw a familiar leek head walking into the maternity ward. In his hands were bags of food and beverages. What is Senku doing in the hospital? Could he be visiting a friend? Though, isn't maternity wards usually don't allow visitors?

"That's weird." Taiju rubbed his chin in confusion. He couldn't comprehend seeing Senku in here. He'd never seen the guy coming here before during Yuzuriha's prenatal checkups.

"Hey, do you think what I'm thinking, love?" Yuzuriha smiled at Taiju. She had some ideas in her head, but rather not voiced it outloud until the scientist told them himself. Maybe he had his reason for keeping this a secret, and she respected it.

"Senku must have really loved children, or he's helping around!" Taiju laughed proudly. Happy at the thought of his friend being a very kind person. Yuzuriha nodded in reply, not denying or agreeing with his statement. Time will tell, anyway. There's no need to think about it too much.

Meanwhile, with Senku, he set the food and beverage on the bedside table. You were nursing your daughter. Though sometimes she would randomly unlatch and cry, which was stressful, but Senku was always there to calm you down or handle her. He sat at the edge of the bed, hands rubbing your arm softly,

"I think I saw Yuzuriha on my way here." He muttered, not too loud to disturb other mothers, but loud enough for you to hear him. You hummed, blinking sleepily at him. He understood the sign and picked the baby from latching to your breast. Then, he set her in the baby incubator.

After that, he helped you sit up properly before explaining, "I bought some sushi. They should be safe. I made sure to ask Francois to make it specifically for you and told them to keep it a secret."

"Thank you, darling." You smiled at him, to which he let out an unamused cough into his palm as his ears began to change colour. There's a reason why you two rarely use pet names. Either way, as long as you were happy, he would let this slide.

It's not like this marriage will remain a secret any longer, so he'd better get used to it. Especially when being called in public places. The great Senku Ishigami may look nonchalant to the public's eyes, but only you, his wife, know what was hidden beneath that calm exterior.

"You're not helping your case here, selfish Senku." Lying down, you rolled on the bed. He just watched you rolling on his legs. To say that it was not tempting to suddenly sit up and watch you fall would be an obvious lie. Though he'd rather not start an argument with you out of all people.

"If you really want to, I could get us something from 'The Francois'." He suggested, stopping you from your… activity. Somehow, his suggestion earned him a frown from you. Why the sour face, though?

"You mean, get him something?"

"Yeah. Same thing." He waved you off, pulling his legs from underneath your weight. He then proceeded to wear a jacket and throw one of his own at your face. "Get up."

Without much thought, you slide into the hoodie and pull the hood to cover your head. Senku hummed as he inspected your fit. It's giving cringe, but he won't say it out loud. With that, the two of you made your way out of the house to the nearby convenience store, The Francois. The infamous shop owned by the Nanami Corporation that somehow has everything one would wish for, including cakes.

He led the way into the pastry section and handed over his card to you. Well, his dad's card, technically.

"Don't you at least want to use your own money for his gift?" You asked as you held the card between your fingers.

Senku shook his head, and an amused scoff left his lips at the idea. Growing up, you were the one who always came to their house to ask for money from Byakuya, knowing how rich he is; so, your suggestion just now contradicts everything you've done so far.

"Says you. Just go and buy him something."

You rolled your eyes and went to the counter to pick some cakes for yourself and Byakuya. Senku wasn't wrong; Byakuya has been spoiling him AND you for as long as you could remember. So, using his money feels like second nature by now.

"I'll have a slice of Chocolate Indulgence, two slices of Burnt Cheesecake…" You ordered, eyes shifting between the rows of cakes. "… Lotus Biscoff Cheese and Chocolat Au Lait, both two slices; packed, and could you write a wish on it?"

The baker nodded and did your orders. After a few minutes, he turned to you, waiting for the wishes you wanted on the cake. You thought about it for a while. Senku would not want the message to be too cheesy, even though that would bring the brightest smile to his old man's face. He's way too nonchalant for his extremely expressive father.

"Do you're old, B—"

"Oh, it's good to see you here! Self-reward for the week?"

Suddenly, Byakuya popped out of nowhere and patted your head. You froze on the spot. The man looked at your stunned face and tilted his head in confusion. But then, he saw his card in your hand, nodding his head in understanding. Oh…

"You're on a date with Senku?" He whispered in your ear, not wanting to possibly embarrass you in front of the other customers.

You almost visibly cringed at his question. A date? With Senku out of all the singles in your Uni? Hell no. You faced him slowly, showing a bright, forced smile.

"Pfff, no way. We're just… snacking, yeah." You laughed half-heartedly.

Byakuya nodded his head, not really questioning your suspicious behaviour. He glanced at the number of cakes you've ordered. He thought the amount was funny. That was, until he noticed a cake with a "You're Old, Bitch" wish written on it.

"Is that for—"

"Senku! Of course! Yes, him." You cut him off. "Senku's been… craving cakes. Maybe it's his hormones changing for being old. Hahaha, isn't that funny?"

"Is that why he's been staring at us for the past three minutes?"

From the table, Senku sighed in defeat. Nothing escapes Byakuya, especially birthdays. How do you think Byakuya always celebrate two birthdays for Senku? One for his birth date, and one for when the old man adopted him. What makes you think it's not hellish suspicious of him to be in the pastry section, ESPECIALLY on Byakuya's birthday, out of all day?

"Awhh!! Senku! You're the sweetest son EVER!" He ran to his son in excitement, but accidentally knocked over a chair's leg and stumbled into a random person, taking him down with him. It turned chaotic within seconds as the person he faced, flat to the ground, turned out to be someone important.

After some police-presence discussion, the ride home was… somewhat normal, thankfully. Byakuya was very happy to discover Senku's presence in the bakery. He had wished for this day during his previous birthday, and it came true! He finally had one birthday where he would not be blowing out candles alone in the kitchen.

In the end, the three of you take turns blowing candles on the cakes at home, for the second time. The first time was at the bakery after the police left, when he sneezed onto the cake as he wept in happiness. You hoped he wouldn't be doing the same thing he did previously. If one might be wondering, why would other people also blow out candles when it's not their birthdays? Because Byakuya wanted you two to, other than that, no, there's no other reason.

"I love you both so, so much!" He wailed as he wiped his mouth. Senku pushed his face away from rubbing his stub on his temple. That thing was hella spiky, and it was freaking itchy.

"Don't get too excited, old man, or you'll be puking everything." Senku reminded him, not wanting to deal with another… similar accident. What happened at the bakery was more than enough.

Byakuya laughed heartily and finished up his cake. The three of you then began cleaning the kitchen. It's already late, but the sun has yet to set. Though Byakuya still insist that you stay at their house. There was no reason to deny his invitation. Besides, staying for the night means you could reduce you electril and water bill by one day.

Now, you were left alone with Senku in his room.

"Looks like you were having fun." He commented as he sat on the bed.

"Define fun. But maybe you were right. It is fun. I feel like a spoiled kid who blows other people's candles." You puffed your chest, hitting it with your palm proudly. Not every day does someone let others blow their cake. Byakuya had just provided you with that rare experience. That just made you treasure the old man even more.

"Do you like blowing that much?" Senku raised his eyebrows at you, a smirk on his face.

You imagined the faces of crying children as you blew out their birthday candles. It's evil, but imagine the satisfaction. "Oh, definitely."

But then something clicked inside your head as you translated the devilish smile on his face. Ew fuck, no. He means it in a dirty way.

"Senku, what the hell?"

"I'm not saying anything; it was your own interpretation."

"What is it that you need me to do, Ishigami?" You extended your arm without bothering to look at his face. Because of that, you failed to see the frown on his face at the way you addressed him so formally, as if you two had never had anything before. But then again, the breakup was weeks ago, and he may be at fault for not moving on as you did.

He shook his head to push those thoughts away. Let's not dwell on the past, especially now.

"I'm concocting a libido enhancer."

A what?

"Libido… enhancer?" You repeated, unsure if you heard him clearly, the first time. Did he miss seeing you squirming like a cat in heat or something? What could be the reason for him to go as far as calling you to be his experiment rat for this kind of test?

"Don't think too much; it's for Yuzuriha. She requested it." What bullshit. He knows it's wrong to use the woman's name for his own selfish reasons. But hey, she herself was sad to hear about the breakup. This little trial he prepared is to uh… bring you… back into… his life, somehow? Surely both Yuzuriha and Taiju would understand, right?

"Sure…" You mumble, not believing it. As if the girl would even think about using such a disgraceful cheat code on her man. Ishigami probably had things in mind when he personally wrote you an email to invite you here after you blocked his number and socials.

Shrugged, you take the test tube from his hand. Twirling the fluid in a circle. Then you glance at him, seeing that almost nervous gulp visible on his neck, as if swallowing a lump. How suspicious…

As you're about to tip the tube into your mouth, his phone rings in his pocket. You glanced at him, then at his vibrating lab coat, then at him, again.

"Aren't you going to answer it?"

"That's probably my old man. He could wait."

"And so can you. Answer it."

Sighing in retaliation, he turned around to answer the call. Once you've made sure he's out of eyeshot, you look around the lab in search of his bag. Thankfully, you found it, his bag, AND his water bottle. Jackpot!

Quickly, you pour the whole thing into the bottle and shake it a little before placing it back where it belongs. Then you stride back to your seat, acting as if nothing had happened. After a few minutes of silence, Senku returned to the lab, muttering something under his breath.

"So, how was it?" You asked, using the test tube as a pointer.

"My old man won't be home tonight. He's just letting me know beforehand." He rubs his hair, thinking of what to eat later, now that he knows Byakuya won't be home for a few days. It'd be troublesome if he had to rely on instant food only to find out they ran out of stock.

"He's one thoughtful father. Sadly, the variant is absent from the germline."

Somehow, your mindless comment struck him. Of course, you just need to bring that up. One of the reasons for you two to fall apart. His hand subconsciously went to his ear to rub that specific spot that aids in calming down.

"Anywho, you drank everything?" He asked, changing to the main topic.

You wiggle the empty tube between your fingers. "It's tasty. You should make this more often. Maybe even mass produce it." You encourage, sarcastically, before setting the apparatus to its rightful place on the table.

Senku hummed quietly as he glanced at his watch. The effect of the substance should take place within 10 minutes. Then he turned his eyes to you, brows quirked.

"Is that so?" He tapped his temple with his index and middle fingers, lost in thought. He could clearly see the sarcasm leaking through your facade, but he'll let it slide. It's not like you're going to listen if he argues with you about it. "Anyhow…"

"It's past 6 pm, and no student is allowed to stay in the faculty building. Go to your dormitory or home, kids. Tsk, younglings these days." Suddenly, a security guard came knocking at the lab door. The old man didn't wait for a reply and just continued his stroll while puffing smoke into the air.

Senku turned to look at you. Then he took the apparatus and kept it in the cabinets after washing them. He wiped his hand with a handkerchief and slung his bag over his shoulder, though, not without taking a sip from his water bottle.

"Do you want to go to the library to record the effect of the concoction?" You suggested as soon as he caps the bottle. He gulped down the water, nodding at your suggestions without saying a word.

With that, the two of you made your way out of the laboratory and went to the library instead. The walk wasn't very far, but it's not very close either. Thanks to this big ahh university. You walked up the stairs ahead of him, but when you reached the top, you turned around to find him standing at the bottom of the stairs, hands on his head.

"You good, Ishigami?" You called, unsure if you should approach him or stay put where you're at. After weighing the pros and cons, you sighed, set down your bag and went to him. Since he was looking down, you couldn't get a good look at his face. So, you crouch next to his legs to peek at his face.

What the helly.

He's… he's… he's red. Like, blush, flush, crush, red. Could this be the elixir's effect? Whoa, crazy. Thank goodness you didn't consume it, but it'd be evil of you to say he deserved it.

"Um, I think… we should head home." He breathes out, turning away from facing you. He grabbed his water bottle and poured the contents over his head. This isn't right. Why is he affected instead of you? He doesn't remember consuming the substance.

Was it when he made it? Could the vapour also work? If so, he had been consuming it for days! But why only today did the effect start? This doesn't make sense. Maybe he miscalculated? Oh shit, if he's already this… affected just by the vapour, what about you, who had drunk over 15mL of it? How strong would the side effect be?

"It's going to rain soon." You muttered, stopping him from whatever he was thinking. His brain was too occupied with his own thoughts to notice you two were already on your way home. He glanced at the sky, it's dark. Before long, a droplet fell on his nose.

He couldn't react properly when you suddenly grab his hand and tug him forward as you run. He heard you yelling something, or cursing at the sky, he doesn't know; when was the last time you two held hands? Maybe over 2 months ago? When did you stop looking for him? He can't remember the details, but if he recalls… he'd never been the one to look for you before. Is that why you want to end your relationship?

Because you were tired of him? Always have to be the one to give, while he only receives. Now that he thinks this thoroughly, he was being rather unfair to you. Focusing and spending most of his time on his experiment instead of on his partner. Did you feel unappreciated? Unseen? But he never missed any important date, so that should make up for the lost time, shouldn't it?

Yet it was never enough. He should've seen it, those signs. But now it was too late. If only he—

"Ha, thank goodness we got home before it starts pouring." You chuckled, taking off your shoes and keep it on the shelf. Then you walk through the hallway of your house, almost forgetting he's with you.

"Oh, you could stay in the living room while waiting for the rain to stop." You added before closing the door to your room. He could do whatever he wants, it's not like he'd never been here before. Besides, his status as a guest doesn't really apply in the house.

Senku took off his shoes and went to sit in the living room as you had instructed. The house is clean, always. It's not too warm, thanks to the pouring rain, but the substance he digested earlier made his body feel abnormally warm. He's grateful your brother isn't home, or he's going to tease the living shit out of him for the blush on his cheeks. When will the libido enhancer wear off anyway?

Shit, his body is getting uncomfortable. The fact that there is an obvious tent on his groin doesn't help. A quick rub wouldn't hurt, would it? Yeah, it'd be quick, surely. The elixir made sure of that.

As Senku sits down on the couch, he adjusts his position to lie down, resting his head on the armrest. His hand began its exploration, the not-so-friendly one. He tried to muffle his… voice with the back of his unused hand. He kept going, up and down, rubbing the wet tip, until—

"Ishigami, do you want some spare clothes? I called my brother, and he told me to let you borrow some." You called from the hallway.

His hand halted its movement, and he quickly wiped the stain on his hands with a tissue on the tea table. He buttoned his pants and pulled up the zip, sitting up properly. You popped from behind the couch and placed the spare clothes on his head.

"Go change." You commanded and left him, returning to your own room. He followed in your step and entered the room next to yours, your brother's. Your room and your brother's are connected by a bathroom.

He went in and showered. Now that he's alone… and the sound of pouring water could overpower his voice, he returned to what was left unfinished. No one could blame him, though! It's the stupid experiment's fault. Now, he's starting to worry about what will happen to you if the elixir takes effect.

He groaned as he fisted himself, releasing to the floor. He feels better now. Quickly, he finished up, wrapped his body with a clean towel and stepped out of the bathroom into the bedroom. He looked up from the floor, expecting to see a quiet, empty room of your brother's; only to see you on your bed, in nothing but a 1-piece sleep dress.

It was nothing explicit, really. The dress was rather modest, covering your top down to your knees, but he just knows you wear nothing underneath it. He always knows. Wait, hold on— what the? If you're in the room, that means he must've accidentally entered the wrong room. Muscle memory, perhaps.

"Uh, yeah. He's showering. Yeah," You were too engaged with your phone call with your brother to notice him approaching. "Pft, no way. We broke up months ago. No, no, we're not engaged in any R-rated activity, you perverted mentalist." You laughed, turning to your side on the bed.

As you shifted, the sight of the ceiling switched to a happy trail of white and green. Wow, how you missed this.

You quickly sit up, facing the half-naked man in your room. You laughed awkwardly at the situation. "Sen— uh, Ishigami?"

Suddenly, he grabbed your ankle and pulled you towards him; your knees hit his abdomen. Giving you no chance to react properly, he climbed onto the bed. You couldn't see his face with his hair down, but the subtle sign on his groin and the red tint on his ears are enough of a sign. Maybe it was a wrong idea to pour that libido-something into his drink.

"Ishigami," you called, though not pushing him away. "What are you doing?" A smirk made its way to your lips. That thing must have been very concentrated for it to affect even THE Senku Ishigami. Look at him getting all worked up, too bad that boyfriend privilege has ended.

"I'm sorry." He muttered. That caught you off guard.

What?

"I'm sorry… for everything." He repeated. He grips your sleeve, frustration evident in his quiet strength. "Forgive me, please…"

You blinked, unsure of how to react. Senku rarely, rarely apologise. Yet something drips from him, landing on your cheeks. He's crying. He's edged to tears thanks to the libido drug.

"…Please…" He let out a sobbed whimper. Sheesh, how could you be mad at this man when he apologises like this?

You shook your head, eyes drifting to anything but his bloodshot ones."Ishigami, you know how you are—"

"I'll change!" He cut you off. That startled you. More tears began to drop from his eyes as he clenched his teeth, holding back sobs from leaving his throat. "…I hate this." He muttered under his breath. He hated how the drug made him so darn sensitive.

"I want the old us. I'll be there for you, just… give me a chance to redo everything." He cried, head fallen onto your shoulder. His tears wet your dress. "Please."

Your hand rested on his head. Fingers slowly rub his scalp; that somehow calmed him down. You sighed softly. "Promise you'll put me before your experiments?"

He nodded his head vigorously, his hair tickling your ear. You smiled, adding more, "and to treat me to dessert every weekend?"

He hummed, rubbing his nose against your chin.

"And… at least three dates a month?"

You heard him mumble a breathy, "Now you're overdoing it… But, yes. I promise."

A contented huff escaped you before you planted a soft kiss on his eyelashes, the closest thing to your lips. Senku seems to understand the meaning behind it, and a big, drowsy smile spreads across his face.

This would be a romantic scene, if not for the hard bulge pressing against your pubic, as he unconsciously dry hump to you. Thanks, libido enhancer, you made him a pervert.

Out of nowhere, he bites your neck, leaving a crescent bruise that will surely be visible after a few hours. You wince at the pain. Then he lapped at the scarred tissue, wanting to soothe you in his own hornily drunken way. Yet as you two were going further, the door to your room slammed open with your brother shamelessly walking in.

"Oh my, dear Senku. Who would've thought you'd be the type to just ravage my sweet lil sis like a rabbit in heat?" Gen hummed, a teasing lilt obvious in his voice.

Senku quickly pull down your bunched-up dress to reach your knees, giving you a little bit of modesty you need. He then glared at your brother, who was shaking his head in mock disappointment.

"And here I thought you weren't engaged in any R-rated activity."

Later, you told him about the elixir and he couldn’t live with second hand embarrassment lmao🤑 imagine fumbled so bad in front of fine shyt and only realise your mistake when they point it out

Byakuya sighed. There's no getting through you, he tried for days, and the outcome has always been the same. You would refuse to do anything but sit on a chair and watch him for hours and hours. It's a pitiful sight, really. He feels bad for both you and his son, the baby too. Being born while under this situation could put a lot more stress on someone.

"Then I'll go find something for you two." With that, he left the hospital room in search of food. He can't have you be too weak. He loves you as much as he loves Senku. If Senku wakes up and sees you as good as dead, the young man would probably be disappointed in him.

After the older man left, you were left alone in the hospital room, listening to the same beeping sound of the heart monitor; staring at him, it made you wonder what he could be thinking about in that comatose state. Would he be relieving all your memories together? Or was it just complete darkness? But then again, neither mattered. You just want him to wake up already.

Meanwhile, in Senku’s mind, he’s once again living as a teen, yet it's a whole different world he lives in. A world where humanity was destroyed by a green beam that petrified almost all intelligent beings, and he is the centre of everything. Not as the villain, but as the scientist who brought back the old world after such a catastrophic event.

"Hohoho, this old man's body may be writhing, but his enthusiasm remains the same. Say, Senku… what more invention do you want to build, now that the Medusa has been defeated?" Old man Kaseki laughed as he stroked his beard, feet thumping against the wooden seat rhythmically.

Senku glanced at the crowd around the research facility. Years had passed since he first woke up from the petrification. So many changes were brought, many lives were lost, yet many more were welcomed. How fast time flies; it almost feels like a long dream.

"For now, I think I'm gonna go and rest my legs." He answered, hands on his hips as he left the site and walked towards the woods nearby. He barely got any rest these days, being occupied with meetings and conferences; a day of rest would be great. Work-life balance is important, too.

He sat on a cliff facing the ocean, feet dangling. The wind blew gently against his skin as his bang brushed his cheeks. It's peaceful here. So quiet… somehow, the silence made him feel lonely. He doesn't understand why, but he feels like something is missing. Like a piece of himself that he doesn't even know ever existed.

"I like the quiet."

A random person came and sat next to him. He scooted further to give them some space. He looked up, and it was you. Uh… someone they probably just de-petrified. He doesn't think he'd seen you before, maybe he did? Not like it matters anyway. There will be waves of depetrification soon, so it's not like he needs to remember every single person they revive.

"Aren't you tired?" You asked him, hand reaching to tuck his hair behind his ear, but he backed away before you could touch him. He turned his head to continue gazing at the horizon.

"Of rebuilding humanity? Kind of, but you could say it's an ambition strong enough to withstand the pressure." He responded, sighing softly in content.

He heard you hum, and then it's quiet once again. Just him, the sea, and maybe you, too. Out of the blue, he felt a weight on his shoulder. You were leaning so closely to him, arms tangling with his own, as you rest you face under his jawline. This is awkward.

"I miss you."

Awkward, "Uh, sure. I think you meant, I missed you." He corrected you jokingly to reduce the tension. Any sane person wouldn't go around clinging to a stranger they just met, would they? You're weird. Not that he'd never seen anyone weirder than this.

"You sleep a lot." You murmured to his skin, as if reminiscing about something he could not… understand. "Aren't you tired of sleeping?"

What's with these questions? Gently, he pulled away from your embrace or whatever and stood up. He turned his back to you and waved you goodbye without bothering to look back. "Well, I gotta go now; can't let those people ruin the lab faculty in my absence."

You just sit there quietly, watching his figure disappear from the woods.

Days passed, and Senku realised he was starting to see you more often than not. Every morning, you would join Francois in helping to prepare everyone's breakfast; in the afternoon, you would somehow be found chatting with Sai in his section of the lab; in the evening, he saw you with Kohaku and Ruri, discussing some… matters; and at night, he saw you with Suika, dinner over a campfire.

It's almost suspicious how you're always… there. So he decided to approach Gen to ask him about this mysterious activity circling you. Strangely enough, the mentalist didn't give out any comments about this other than, "You're imagining too much, my dear Senku! Oho, don't tell me it's happening now?"

This teasing crap again. Senku ended the conversation right then and there and went into his private lab. Only to find you sitting on his lab table, vials of dangerous chemicals in your hands. How did you get in here without his special entry card?

"Okay, this is overdoing it. Do you need something from me, or what? You've been following me for days now. It's eerie." He stated, growing uncomfortable with your constant presence in his life. Don't tell him you're actually a ghost from a body they accidentally destroyed or something?

"Nothing. I just miss you." You smiled at him. He cringed at that. Hearing that twice doesn't make it any better.

"Do you need a therapist? I could ask Luna if she knows anyone." He suggested going to his table to start his experiment. There are lists of things he needs to get done before sunset. You didn't reply to his suggestion and continued to do your thing: staring at the glass dome over your head. His lab was built with easy access to stargazing; Senku loves astronomy after all.

He ignored your presence and started crossing lines on his checklist. More and more tasks were done, and he could go home and rest. Before he left, he gave you his card to make sure you lock it before leaving in case you want to continue your… activity, and remind you to return it before 9 tomorrow morning.

Just like that, his day is filled with pictures of you. In every blink of his eyes, he would see you standing or sitting somewhere. Whenever he accidentally fell asleep, you would be by his side, sitting on the table as you pat his back, lulling him. Every time it's lunch time, you would pop out of nowhere and join him. Here a you, there a you, everywhere a you, you.

Before he realises it, he's getting used to seeing your presence. Maybe even expecting to see you more than once a day. The fact that you wouldn't hesitate to just hug or touch him doesn't help either. He wondered where you gained that confidence from. It was as if you've known him more than he knows you, to ignore any sort of boundary he sets up.

Years passed, and uh… welcome home, Mrs Ishigami. He, himself, was surprised that he could get you to marry him. Well, you did say that you miss him more than a hundred times over these past 2 years. It's not like he minds it; he finds it rather cute that you would always cling to his arm like a penguin as he drives while murmuring about your day or whatever that crossed your mind at the time.

"This feels like a long dream." You said softly, hugging his arm. He nodded, a smirk adorning his face.

"Do you not have any more lines in your dialogue script, other than 'I miss you', 'Aren't you tired of sleeping?' or 'This feels like a long dream'?" He joked, pressing a kiss on your head as he drove. One hand on the steering wheel, while the other on your thigh as you clung to him.

"Then, how about—" you lean forward to look into his eyes, "I'm sorry."

He looked at you confusedly. What were you apologising for? He opened his mouth to say something, but then he heard loud honking, and he didn't have the chance to react properly when the truck hit your side of the vehicle, successfully murdering you within seconds. The car was totally wrecked, with only your arm clinging to his as your body… was nowhere to be seen in the wreckage.

Everything was happening so fast. One moment, he was with you, being all lovey-dovey, and now he's standing in front of your grave, a bouquet in hand. He placed it on the ground, where your crushed body lies resting.

Yet as he stepped away from the graveyard, he heard the sound of crying from a tree. Did someone leave a child here? He approached the voice, and true to his instinct, it was really a child. A newborn girl at that. How could someone be so cruel, leaving a newborn by herself?

He glanced around, in case the child's parent might be nearby. Seeing none, he picked her up, holding her close to his chest. She looks so tiny, so cute, so warm… so confused but sad.

Droplets of tears fall onto the baby's cheeks, stopping her cries. Why does she look so much like you? The resemblance was uncanny, it's almost scary. He wiped her tears and gently rocked her to sleep under the tree. After the baby quieted down, he sat down and rested his back against the tree trunk.

All this crying is making him sleepy. Just a little nap won't hurt, right? Maybe when he wakes up, all of this nightmare might turn out to be a long… long dream.

In the real world, the sound of the heart monitor filled the quiet hospital room. Accompanied by the soft rustling and groans of a baby, who was bundled in a blanket right next to Senku's leg, sleeping peacefully on his bed.

Senku blinked his eyelids open. His body feels so heavy, strangely heavy, as if he's been napping for months instead of a quick nap under the tree. He moved his fingers and accidentally grazed the top of the baby's head.

Oh, they must've brought her here, too. He thought.

He remained quiet as he stared at the ceiling. His head feels foggy and dazed. How long has passed since your death? Two days? Three? Who fed the baby while he was out cold?

"Sen… senku…?"

He heard Byakuya's voice calling his name. Wait, what? Byakuya? His eyes drifted to the man entering the room. This can't be real. Byakuya died millennia ago. This must be hallucinations. Five stages of grief happen to everyone after a great loss, after all.

He had overcome Byakuya's death over the past years of rebuilding humanity in his footsteps. He could handle this hallucination. But if it were you, he doesn't think he could handle it without breaking down into tears. Your passing is very recent, and he's still grieving.

"…" This gotta be a crazy dream. He breathed out, his voice not coming out, his comment only audible in his head.

Byakuya rushed to his side, careful not to startle him or cause any damage to his son's already weakened body. Tears flow like a river from his eyes, followed by never-ending snot. Senku would've grimaced at the sight, if not for his lack of awareness.

"Senku… you're finally awake. It's been 4 months, son!" Byakuya cried, blowing snot using the baby's saliva handkerchief. He hesitantly uses his hand to caress Senku's sunken cheek. "Your wife is outside, getting the baby's diaper. She'll return soon, so don't cry, okay?"

Cry? Senku wasn't crying. Or was he? He could hardly feel his body; worse, he couldn't speak his mind with his throat refusing to cooperate. And wife? What wife? His wife, you… died days ago. Did Byakuya's ghost come with yours, too? Also, what 4 months is he talking about? Then, he heard the sound of the door creaking as you entered the room.

"Bya, have you fed Asun—" Your question was cut short when you saw Byakuya sobbing, with Senku looking at you as if he's seeing a ghost. You almost dropped the juice box in your hand as you stood there, unmoving.

The tears that flow from seeing Byakuya turned into a breathless, choked sob. You're alive? Or is it really just his imagination? He can't tell which is real, which is not. Everything is happening way too fast.

"I miss you." You muttered as your shaky legs brought you closer to him, then you shook your head with a teary smile on your face, "No, I missed you."

Those simple 3 words clicked something in his mind. Those are one of the three sentences you always said to him, even the first thing you said when you met him during your first meeting.

"This feels like a dream." A whisper left your lips. That. Another one of those. The gear in his brain slowly moved, connecting two and two: 4 months, Byakuya is still alive, you are still alive, these same sentences…

Was he in a coma? And those adventures going to the moon and defeating Why-Man were all just a long, long dream? Earth was never petrified, and it's just his imagination all along? Then, does that mean those same sentences you keep uttering in his… Dr Stone world, were you actually talking to him while he's unconscious?

But then, why didn't he remember you in his imagination? Did he lose his memories before he fell into a coma? Is that why?

Senku was too indulged in his thinking world to see you holding the baby in your arms as you sat next to him. Oh, about the baby… is it his and yours, or did Byakuya find it under a tree somewhere? He wanted to ask, but no words could escape his lips.

"You should see our girl. She looks just like us." You hold the baby closer to him, but not too close to overwhelm him. Byakuya already did that part. You wouldn't dare to shove your face into his when he is in this state. Unlike a certain someone.

Senku's eyes slowly drift from your face to the bundle in your arms. You're right. She looks just like you two, but mostly you. He loved her. A weak smile deliberately formed on his face.

Senku has so many questions he wanted to ask, so many things he wanted to say, but for now, he would rather just enjoy himself in this quiet warmth (not so quiet with Byakuya still sobbing) with the people he loves. Whatever speculation about that mysterious world he lived in for thousands of years could be discussed later.

He just wants to enjoy his time with you, his wife, again. After all, you will always be the person he would fall in love with again. If not twice, maybe this would be the third time.

Get it?! Because he fell in love, and forgot, then fell in love again (in Dr Stone world), and was ready to fall again because that dream world wasn't exactly a reality. (๑•᎑•๑)

"Think of something." He urged as soon as the light from the machine attached to his head lit up. You sat in front of him and propped your chin on your palm, unamused.

"Okay, read my mind now." You muttered, tapping your index finger against the table. Senku closed his eyes as he adjusted the wave meter to get a good frequency of your brain, synchronising his own with yours.

"Try to think of a number." He encourages, eyes closed, brow furrowing in focus. If his calculation is correct, he should be able to hear your monologue in three… two… one…

"Senku… senku… senku…" He heard a small voice, like a whisper in his ear.

"Quiet, I think I hear something." A smile made its way to his lips. "This is exhila—" He opened his eyes to break the news to you. Only to see your face right in front of his, as you call out his name in a whisper in his ears. So, you were fucking with him. He shoved your head away from breathing in his face.

"So? How did it go? What number was I thinking?" You asked, but it feels more like you were trying to rage-bait him with your question. You returned to your seat with a mischievous smirk on your face. This is fun.

Instead of answering your attempt to get a reaction out of him, he shifted his attention to his experiment. There has to be something he had miscalculated for it not to work, but oh well, a mind-reading machine is a crazy invention itself. Trying to get it to work on the first try is basically Mission Impossible.

Plus, it's a trial-and-error work. There's no guarantee he could actually get a wonderful result out of this trial. Still, so much time was wasted, and he couldn't simply give up just after one failed test. Yet, if he were too eager to try to read your mind, wouldn't it be too suspicious of him?

"Maybe you wear the thing wrong? Let me adjust it." Your hand quickly reached for the pad on his temples. But out of nowhere, he grabbed your hand before you could get too close to it. Your comment made him realise: what if he placed the resonators wrongly?

"I have an idea. Come here." He gasped, quickly plucking one of the two wired band-aid machines from his temple and stamped it to yours. He calibrates the frequency again and…

— Uh… bzzt— hm—

"Think of something, quick!" He commanded in a rush as his eyes continued to read the data on the computer screen while his hands hovered over the keyboard and the control remote.

How much wood would a woodchuck chuck if a woodchuck could chuck wood?

"…" He stared at your face, unblinking. Whether it was from this discovery or something else entirely, you don't know.

Dang, look at that face. Full of disappointment.

"Mudsliging me, huh?" He chuckled, earning an excited yet confused look from you.

"Sounds like it's working." You nudge his shoulder, giving yourself a back pat for your bright idea. Technically, it's not entirely yours, but who cares?

Now, how do I keep my head empty? Do I think of something funny and keep it SFW? Wait, hold on a second. How come I'm not hearing anything?

"That's because you're attached to the positive terminal of the machine. That means I'm the only one receiving the wave generated by your brain, silly." He explained, though not without calling you dumb names. How Senku-like of him.

Tsk, so unfair. Just when I thought I could finally know what's going on inside that big brain of his.

"Stop moping. Let's start with our first test." He ignored your monologue-wailing and began prepping papers to collect data from you. "Think of a fruit."

You sit down, facing him, knees to knees. You imagine a fruit on a plate, light yellow, with some green parts. Not fully ripe. Long and… a banana! You smiled to yourself, proud of the image formed in your head.

"That looked like a banana." You heard him mutter.

"You could see brain images, too?" This experiment is truly something else. Who would have thought Senku could be a psychic like that pink-haired guy from an anime called Saik—

"Now imagine what you would do with it." He interrupted your thought.

What would I do with a banana? Eat it, of course.

"Then do it." He replied to your thought.

Following his order, you quietly imagined yourself lying down in bed, reading some smut while eating a banana. A wonderful scenery indeed. As you eat, you cringe as the reader in the smutshot said something cringeworthy, almost choking on your fruit.

This feels like watching those alpha CEO x y/n fic on Tumblr. But hell yeah, those explicit scenes were mad detailed. From the way their skin glistened to the way he manhandled the reader. Peak fiction, for real. If only it were you and Sen—

"I would suggest you keep it PG-13. We may no longer be minors, but I'd rather not write intercourse mind tape as my first mind-image reading." Fuck, you completely forgot about him.

"I wasn't thinking of anything inappropriate, you accuser." You tried to defend yourself. Though it works like hiding a candy under your tongue for a dentist visit. Worthless.

"Yes, definitely." He shook his head and turned around to write down the first part of the reading. After a moment, he glanced at you. "About the last part…"

"Of the smut? Wow, Senku. So shameless of you to be asking a lady such a question." A mocking smile made its way to your face while his scrunch in disgust. Haa… teasing this man has never been more satisfying. That makes you realise, how the heck did you two become friends again?

It was last winter, you were out at the park, watching over some kids you babysat. You taught them how to make a snowman, and they made a big ahh wiener out of it and proudly presented it to you. And instead of being mad at them, you praised their artwork and snapped a picture of it. At the same time, the almighty Senku was on his way home after a hangout at Taiju's house.

He heard you chatting with the kids about your dream man who could read minds, so that you don't have to tell them what to do during intercourse. You were giggling to yourself like a pervert as the kids watched, wondering what inter…course means. Well, big people stuff, rents and craps, whatever. That piques his interest in building a mind-reading machine.

It's not like he started with building this machine so he could read your mind as you two did the deed, but more towards the idea of being able to understand someone's deepest unsaid words. It's quite poetic in its own scientific way, if he thinks about it.

With that objective in mind, he approached you, and that was how you two became friends. He never mentioned anything about building the machine after hearing your perverted vision; instead, he keeps you by his side as someone who would somehow light up his world, even when you came from nowhere. How did your position in his life change so much within a short time?

"And she ended up with triplets." You finished your summary of the fic of your imagination. An embarrassed look on your face turned into a fluster. Wow, hearing smutfic made him smile that much? Who would have thought that he could blush? It couldn't be the experiment, could it?

"If you're smiling this much, I believe that means this experiment is a success?" You lean forward to gain his attention. How long has he zoned out, you wonder.

"It is. But there'll be more experiments yet to come." He set the pen down and turned to face you. "Hope you're willing to be my test subject."

You rolled your eyes at his playful commentary, "I agreed to it months ago. Plus, you promised to treat me to something pricey after every lab-rat experience. I hope you have your wallet filled with cash?"

Without shame, he pulls out Byakuya's card… :|

As long as it has money, you're never going to question how he persuaded his dad for such an exchange. After that, he concluded the day's experiment and took the band-aid-like machine from your temple, disconnecting his mind from yours. Somehow, that made him feel incomplete.

"We should try this new Takoyaki stall near the airport. I heard they made a big sale in their first week. We definitely need to check it out." You took out your phone and showed him the location. After receiving a nod from him, you skipped out of the lab.

Meanwhile, Senku quietly watch as you leave him behind for food. He hummed to himself before joining you from behind after he made sure every apparatus had been cleaned. As he walks behind you, he wonders:

Say that he could have your hand in marriage, would he be able to fulfil your… fantasy? After all, you were the reason he built this mind-reading machine, anyway. It'd be a waste if he were to let you go just like that. He called out to you. "Stop skipping. You'll fall."

"You'll be the one to fall first!" You shouted from almost 50 meters away from him.

You were right, but I have long fallen.

The world returned slowly, like a film reel restarting with stuttering frames.

Rain began to fall, hesitant at first, then harder, a rhythmic drumming that brought the scent of ozone and damp earth. The storm had passed in its wake, but something remained: a sense of displacement, of threads severed and poorly reattached.

Senku's colleague stirred first.

Her body felt foreign — limbs too light, too long, too... wrong. Fingers twitching, legs struggling to coordinate. But worse was the sensation inside her skull, like her own thoughts were echoing through a cavern she didn’t recognise.

She pushed herself up and froze.

Pale fingers. The shape of her hands was larger than she remembered. Her voice, when she gasped, was not hers. It was deeper. Sharper.

"No..."

Across from her, another figure lay sprawled on the grass, unconscious. Familiar clothes. Familiar hair dampened by the rain.

Her body.

The horror hit in waves. She crawled to it — him — herself — and shook the shoulders with trembling hands. "Wake up," she hissed— "Senku — wake up!"

His eyelids fluttered. Groggily, he sat up, groaning. And then... froze.

His gaze darted to her. Then to his own hands. Then back again.

"What the hell..." His voice caught in his throat. Thin, and airy, unmistakably hers.

She staggered back. "It happened," she said. "It really happened."

"No," Senku said, but he was already reaching for the portable terminal, fingers fumbling awkwardly through code commands, mind moving faster than his borrowed body could follow. "No, no, no — this isn't possible—"

She knelt beside him, grabbing his arm. "Senku— stop."

His breath was ragged, his movements erratic. He couldn't stop looking at her — his body, his face, distorted by panic.

"This is— neurological dissonance. Temporary. Must be," he muttered. "Memory displacement. Haptic hallucination. There’s no scientific model where identity transfer—"

"There is now," y/n interrupted quietly. "Because it happened."

The silence that followed was unbearable. Thunder rumbled again in the distance, softer now. A reminder. A whisper.

Senku's face — her face — tilted toward the sky. And something shifted in his eyes. Not just fear or confusion, but wonder.

Wonder...

"Huh," he said finally, voice strangely calm. "Guess you were right about chaos."

She looked down at her — his — hands. "Yeah," she murmured. "But it looks like you're stuck with it."

The walk back to the facility was a silent one, broken only by the crunch of gravel beneath mismatched shoes and the slow dripping of rain from tangled leaves. The storm had passed, but its echo lingered in the sky. Thunder murmurs like distant voices arguing behind the clouds.

Senku, trapped in y/n's frame, walked with stiff precision, his gait subtly off. Too cautious, and maybe too calculated, too. His borrowed body moved differently than his own as his hips swayed slightly, his centre of gravity shifted forward, posture was more fluid than rigid.

y/n, wearing Senku's tall, lean form, moved with equally awkward grace. His longer legs carried her farther with each step, but his body was a vessel of constraint. Everything about him was efficient, but not built for ease. His shoulders resisted the way she carried tension. Even blinking felt alien — his eyes are way too sharp, keener, too attuned to light.

Neither said much until they reached the lab.

Senku reached for the door first, hesitated, then stepped aside. "After you," he said dryly, but not unkindly.

She paused. "Really?"

"It's still your soul in my body. Might as well respect the formality."

She raised an eyebrow, then stepped inside. The familiar scent of ozone and solder greeted her — electrical insulation, old books, faint notes of mineral oil. It felt like stepping into a cathedral dedicated to reason, except she now wore the robes of the high priest.

Senku shut the door behind them with a quiet thud, then immediately crossed the room, fingers flying over a terminal. "I need to scan our neurophysiological vitals. Something's got to give me a baseline. If we can isolate the inversion pattern—"

"Senku."

He paused.

She leaned against the counter, arms crossed in a way that didn't suit his body but felt instinctive. "It's been half an hour. Don't you think we should... I don't know... go home?"

Senku turned slowly. "Home?"

"Yeah. Your home, and mine." She gestured between them. "Which means...you're going to have to go to my apartment. And I have to go to yours."

Senku blinked. "Absolutely not."

"Well, we can't just sleep here."

"Why not?" he snapped, a little too fast. "It's a controlled environment. I've got all the tools I need here, and it's not like I'm planning to stay in your body long enough to need pyjamas."

Her eyes narrowed. "You really think you'll reverse this overnight?"

"I intend to."

"Well, I don't." She sighed and stood straighter. "Look, I get it. You're trying to rationalise this like it's some solvable equation, but even if it is, you're not going to fix it by refusing to breathe fresh air or pretending reality isn't inconvenient."

Senku glared, then looked away, jaw tight.

She softened. "Besides... there are people expecting us. Your father, my roommate, our colleagues. They'll notice something's off."

"...Right," he muttered, rubbing the bridge of his nose in a gesture that looked alien on her face. "Social variables. Damn it."

There was a pause. A long and heavy one.

"Alright," Senku said finally. "Let's just swap keys and keep conversation to a minimum."

She gave him a look. "Yeah, that'll go great when my roommate asks why I'm acting like an emotionally constipated android."

"And my dad will love it when you start offering emotional insights during dinner. 'He's being so expressive lately,' he'll say. 'How wonderful!'" His voice went high and mocking.

She smirked. "Guess we'll both be playing pretend."

They exchanged bags awkwardly: Senku gritting his teeth as he fumbled through her belongings, y/n grimacing as she rifled through his gadgets and layered notebooks. Their lives had always run parallel, but never intertwined this intimately. Not until now.

"You have way too many tools," she muttered.

"You have way too many lip balms," he replied flatly.

"Some of us care about hydration."

"And some of us care about solving the mysteries of the universe."

"And some of us care about not having cracked lips while solving them."

Senku rolled his — her — eyes. "Whatever. Let's just survive the night without getting each other arrested."

She gave him a sardonic salute. "Good luck, genius."

"You'll need it more than I will."

Outside, the world was soaked and glimmering. Wet streets reflect the haze of streetlights like liquid gold. As they went their separate ways, each with the other's burdens, each wearing a mask they did not choose, the city held its breath.

The storm had passed, but the true thunder had only just begun.

Posting this here because why not? Heh. Also, I'm trying something new. Yeah, these coloured texts... are they hard to read?

"Snack time, darling," he announced softly, shaking a small container of shrimp pellets before tossing them into the water.

The alien drifted closer, catching the pellets in slow, almost bored motions. They usually glowed faintly when eating as soft pulses of light shimmered through the water like a heartbeat, but today... uh, nothing. The glow stayed dim and almost nonexistent, which is weird. Very.

Gen tilted his head. He knew exactly what was going on, but it would be wiser to act oblivious, no? "Not hungry, or just feeling blue?"

The alien didn't bother to react to him. Not with expression, not even with light. Just methodical movements, robotic almost.

He sighed, leaning his chin into his hand. "You know, you're really killing the vibe today. Usually, you're all sparkly and glowing like a nightlight. What gives?"

Still nothing.

Gen's lips twitched into a small, mischievous smile. If words wouldn't draw a reaction, perhaps something else would. Hehe. He plucked one of the shrimp pellets from the container and, without much thought, popped it into his mouth.

Instant regret, bro.

He coughed lightly, wincing at the dry, salty crunch. "Ugh, eug, uwegh, uh yeah, that's definitely made for you, not me." He forced a grin, pretending otherwise. "Delicious. Truly gourmet. Maybe I'll open a restaurant for us. 'Alien Cuisine by Gen Asagiri.' Catchy, huh?"

The alien blinked at him once, slowly. What is wrong with this being they wondered. He took that as encouragement anyway.

"Anyhow," he continued conversationally. His tone was smooth, almost casual, "How's the food today? Not to your taste? Or maybe you're just... I dunno, distracted?" He gestured subtly toward Senku and Kohaku in the distance. "They do look cute together, don't they?"

No response. Wonderful.

He leaned closer to the tank, lowering his voice as if confiding a secret. "You know, a lot of people in the village think those two are going to end up together. Can't say I blame them. They've got chemistry. Haha, see what I did there?"

"I mean, a lioness and her lion. Works like king and queen, no? A perfect... perfect mate."

The alien's gaze flicked toward him, faint glow rippling once.

"Ah, so you are listening," Gen murmured, smile sharpening slightly. "I mean, you saw it, right? The way Senku's eyes lit up when Kohaku came in? Happens every time she shows up. Some say he's got a crush on her."

He tapped the tank lightly, eyes half-lidded but observant. "What do you think? Is she beautiful?"

The alien's expression didn't change much (not that it ever did), but something subtle shifted in their posture. Their fins drew closer to their body. The faint lines of light along their skin flickered, then dimmed further. They stopped eating completely, pellets drifting past them untouched.

Gen watched silently as the alien's eyes flicked between him and the pair across the room. Senku was still talking, gesturing absently with his pen, and Kohaku laughed at something he said. So brightly, cerefree, and so... utterly human.

The alien stared at them for a long while, motionless. Then, slowly, their gaze returned to Gen. Their eyes, those faintly luminous eyes, searched his face. Wordlessly questioning his actions, or rather, his words. What was he trying to gain from this?

Gen only smiled back, soft and unreadable. He didn't confirm anything, but didn't deny it either. Instead, he just sat there with that same amused calmness that never quite reached his eyes.

After a few seconds of silence, the alien finally turned away. They picked up one of the pellets, almost mechanically, and resumed eating. No glow returned this time. Only a quiet, dull rhythm of movement.

Gen exhaled quietly, his grin fading into something more neutral. "Guess that hit home, huh?" he muttered to himself. He didn't press further.

A few minutes later, Kohaku finally seemed to remember there was an alien in the room. "Oh, right!" she exclaimed, stepping closer to the tank. "So this is the one Stanley's been talking about!"

Senku looked up from his notes. "Careful, the glass is pressure-sensitive."

Kohaku ignored the warning, leaning in with bright eyes. "Whoa... you're one beautiful jelly-head humanic alien fish!"

The alien froze mid-motion.

Compliment — a sound they didn't quite understand but could feel. It was the warmth behind it and the excited tone. It wasn't analysis like Senku's or teasing like Gen's. It was simple and pure. An admiration of a being unseen before.

For the first time that morning (I think?), their glow returned. Though it was faint and uncertain, it was undeniably there. Kohaku smiled wider. "You're glowing! Does that mean you're happy?"

Senku gave an exasperated sigh. "It's just bioluminescent response to emotional or environmental stimuli."

"Uh-huh," she replied, clearly not listening.

Gen watched the exchange with quiet amusement, resting his chin on his hand. He noticed the way the alien looked at Kohaku. It was not with the cold curiosity they usually had, but something softer. Like they were confused. Maybe even... shy.

That made him wonder if the alien was beginning to understand what it meant to feel. Or has they always been?

....

Night settled quietly over the lab as all the voices and footsteps had long faded away. The hum of the machines filled the empty spaces, lowly and steadily, like the pulse of a heartbeat. The faint blue light of the monitors cast long shadows against the glass, painting the room in sterile calm.

Senku was the last to leave. He stood by the main console, scanning the latest readings on the holographic display.

Oxygen saturation: stable. Core temperature: slightly elevated, though still within range. Neural activity: steady but showing faint spikes during rest cycles. Something that had begun only recently.

He tapped the screen thoughtfully, lips quirking.

"Dreaming, huh?" he muttered under his breath, though the thought fascinated him. If the alien could dream, it implied higher cognitive processing; imagination, maybe even memory retention. That would change everything about their understanding of its neurology. He made a mental note to monitor it more closely.

Next, he flipped through the rest of the data: trace mineral composition, feeding response times, and muscle regeneration rate. The alien's adaptability to Earth's oxygen levels had improved exponentially in the last few weeks. Their fins had developed a subtle iridescence under UV light. Perhaps an evolutionary response to the solar spectrum? He scribbled quickly into his notebook, scrawling half-legible formulas and hypotheses across the page.

"Tomorrow," he said softly, glancing up from his notes. His gaze flicked toward the window, where the faint moonlight poured in, silvering the outlines of the lab. "We'll try expanding your perimeter."

He looked toward the tank again. "There's a field behind the solar cells. Big, open space with no wind tunnels. One that has a good balance of moisture and heat. You'll get enough light there for proper photosynthetic calibration, if that's even what your skin's doing. And the soil there's got higher trace iron. It might react with that mineral compound in your dermal tissue. Worth testing."

His tone stayed even and calm, but there was a rare, quiet warmth under it. ( ⸝⸝´꒳`⸝⸝) He adjusted a few settings on the console; lowering the filtration rate to mimic night-cycle conditions, then tapped the tank's surface once with a knuckle. A habitual gesture of his. "Rest easy, alright? Big day tomorrow."

The alien floated near the glass, unmoving except for the faint pulse of their glow beneath the water.

Senku lingered just a second longer, staring at them; at how still they were, how.... quiet. Something about that silence always stirred an odd thought in him: intelligence without sound. Communication without language. He wondered what kind of society produced that? A world of thinkers who never needed to speak.

He shook the thought off with a quiet exhale and reached for his logbook again, jotting down one final line in his spidery handwriting:

"Plan: test light response beyond the controlled area. Observe locomotion on natural soil. Record photochemical reaction and body temperature changes. Possible behavioural deviation outside confined environment — record closely."

He tore the page from his pad and pinned it to the board beside the console. Then, after one last glance toward the tank-- I mean, toward the alien's soft luminescence swaying like underwater starlight, he straightened, rolling the stiffness from his neck.

"Tomorrow, then," he murmured.

And with that, Senku turned, his lab coat brushing softly against his legs as he crossed the room. The automatic door hissed open, releasing a brief draft of cool night air before sealing behind him.

The lab fell silent again. Save for the rhythmic hum of machinery and the faint, breathing pulse of light from within the tank. The alien stayed where they were, body gently drifting with the current, eyes tracing the ceiling lights until they dimmed one by one. The sound of the filters... the soft trickle of bubbles... it was all familiar. Safe, even. But tonight, it didn't feel quite right.

Something inside them stirred. Restless, how strange. Some kind of tightness in their chest that they couldn't name. Their glow pulsed faintly in rhythm with their unease, each flicker a quiet question they couldn't ask.

They closed their eyes, letting themselves sink deeper into the water, until the world turned quiet and the weight of thought slipped into dream.

Home. (๑•́ -•̀)

Morning came softly to the Kingdom of Science. Pale sunlight spilt through the glass roof of the laboratory, tinting the floor in a faint, gold shimmer that glided across the walls and metal counters.

Senku arrived not long after dawn, coat dusted faintly with mist from the early river fog. Gen trailed behind him, yawning dramatically while balancing a steaming cup of something that was probably coffee, or as close as science could make it.

"Morning, our darling alien head," Gen called with his usual lazy grin as the door hissed open.

The alien stirred inside their containment tank, drifting upward from where they had been curled near the bottom. Their bioluminescent lines glowed faintly, sluggish and pale at first, as if they had just woken from a deep dream. Their gaze moved languidly toward Gen, unfocused.

Then they saw Senku.

In an instant, the alien's glow brightened, a soft bloom of colour spreading across their form. Their fins lifted slightly, eyes sharpening with alertness. The difference was immediate and impossible to miss.

Gen let out a knowing hum, sipping his coffee. "Heh. Someone's got a favourite scientist," he murmured under his breath, earning an unbothered side-eye from Senku.

Senku adjusted his gloves. "Their photosensitivity just reacts to familiar figures, that's all."

"Uh-huh," Gen replied, voice steeped in amusement. "Whatever helps you sleep at night, dear Senku."

Senku ignored him. He approached the control console, checking the tank's data display. "Morning routine might be delayed today," he said conversationally, glancing at the alien. "You'll get your sunlight later. Kohaku and the others are returning from their expedition this morning, and since Chrome's still away, I'll be handling the welcome myself."

The alien tilted their head, eyes blinking once, slowly. Of course, they didn't know who Kohaku was, but Senku still explained. His voice was steady and patient, as he often was when teaching. He described Kohaku's golden hair, her unyielding spirit, and the journey she and her group had taken across the mountains to gather new minerals.

They listened, or at least, it felt that way. The water rippled gently each time his voice shifted tone.

Afterwards, Senku resumed the day's procedures. "Alright, let's start with baseline readings. Gen, you handle the monitor."

Gen nodded and set his cup aside, activating the holographic interface. Together, they moved through their practised routine: water temperature, oxygen levels, nutrient composition, and finally the alien's biometric readings. Senku read out values while Gen noted them down, the hum of machines and the quiet bubbling from the tank filling the silence.

"Heart rate consistent," Senku murmured. "Oxygen intake normal. No metabolic deviations from yesterday."

Gen smirked. "Guess even otherworldly beings get comfy once they've got their shrimp buffet, huh?"

Senku snorted lightly but didn't answer.

They were halfway through recording when the door burst open.

"SenkuuUUuu!!"

The voice was bright and familiar — too loud for the sterile lab air. A flash of yellow streaked past the threshold before either of them could turn fully. Kohaku, sun-kissed and grinning from ear to ear, charged straight toward Senku.

Before he could react, she threw her arms around him in a tight, bone-crushing embrace.

"—Tch, oi, careful with the equipment!" Senku's voice came out strained, though there was a rare flicker of warmth in his tone. \(´ཀ`」 ∠)_ He's mine bro.

Gen chuckled behind him, hands tucked in his pockets. "Can't blame her. Been months since she's seen you. You should feel flattered, you know."

Senku rolled his eyes but didn't push Kohaku away, allowing her a moment before gently setting her back. "Welcome back, Lioness. Guessing the expedition was a success?"

Kohaku grinned wider. "Of course it was! You'll be impressed when you see what we brought back."

As they exchanged words, Gen turned to resume the data readings. But as his gaze flicked toward the tank, his amusement faltered.

The alien's markings: those luminous veins that traced along their body were flickering, dimming and brightening in quick, uneven pulses. Not the calm rhythm of contentment, nor the soft, steady glow of curiosity. It was erratic. Uneasy.

Their expression, once neutral, had shifted. Their eyes, which were usually placid and unreadable, now carried a faint shadow of something he couldn't quite name. Their fins lowered as the water around them stilled.

Gen frowned slightly. "Huh…"

He watched as the alien's glow dimmed almost completely before stabilising into a faint, pale hue. Their gaze wasn't on the machines anymore. It was fixed on Senku… or rather, on the sight of Senku and Kohaku laughing together.

That look, it wasn't confusion this time. It was something heavier. Gen recognised it instantly, though he didn't say it aloud.

Jealousy. He exhaled slowly through his nose and turned back to the console, pretending not to notice. "Measurements look stable," he murmured instead. "Everything seems fine. Time for your morning shrimp pallets, hm? "

But out of the corner of his eye, he saw the alien lower themselves toward the bottom of the tank, curling slightly, faint light fading until they looked like little more than a shadow beneath the surface.

And for a moment, Gen wondered, not as a mentalist turned scientist's assistant, but as a man who understood emotion far too well. If the alien truly grasped what it was feeling, or if it was just instinct trying to mimic a heart.
