“I do not take students,” Nanami said, adjusting his tie, in a practiced motion.
You looked up at him, your eyebrow raised slightly in disbelief, “Then why am I here?”
“Because the higher-ups have decided I have no choice in the matter,” he replied evenly after a brief pause. “Unfortunately, neither do you.”
You let out a short, annoyed breath, shifting your weight as your arms crossed more tightly over your chest. “This is stupid. I’m eighteen, I don’t need a babysitter following me around.”
Nanami exhaled through his nose quietly, as he rubbed the bridge of his nose, as if trying to relieve a tension that had nothing to do with you specifically but everything to do with the situation itself.
“Do you genuinely believe I would choose to spend my time like this?” he asked after a moment. “I have work that is significantly more important than supervising someone who insists they don’t need supervision.”
“I don’t need help,” you said again, a little sharper this time, shaking your head as if repeating it would somehow make it more true. “My grades are fine.”
Nanami adjusted his glasses slowly, pushing them back up the bridge of his nose.
“Clearly,” he said after a short pause, his tone flat but deliberate, “which is why you’re standing here being assigned to me.”
“Ugh, don’t say I’m assigned to you,” you groaned, rolling your eyes as you looked at him with obvious annoyance. “You don’t own me. I could just not show up.”
Nanami didn't respond immediately. Instead, he walked over to his desk and lowered himself into the chair. The surface was perfect - with neatly organized stacks of paperwork arranged in perfect order.
He picked up a black pen, absentmindedly twirling it between his fingers as he glanced over one of the reports before finally lifting his gaze to meet yours.
“You are welcome to do that,” he said evenly, his voice calm. “However, if you choose not to attend your training, your attendance will be marked accordingly, and you will be required to repeat this school year.”
Your confidence faltered almost instantly.
You swallowed hard, the realization settling uncomfortably in your stomach.
High school had already been miserable enough the first time around. Endless assignments, constant expectations, and classmates you could barely tolerate, it had taken everything in you just to make it this far.
You were finally in your third year, only months away from graduating, and there was no way you were going to throw all of that away over one aggravating mentor.
“Fine,” you sighed, dropping into the chair across from his desk with a reluctant huff.
Nanami remained silent as he reached for a blank sheet of paper from one of the neatly organized stacks beside him. He placed it in front of you before leaning back slightly in his chair, his hands resting calmly in his lap.
“Here,” he said. “Show me what you know.”
You frowned at the empty page before looking back up at him.
“So what am I supposed to write?”
“Anything,” he replied, “Write an essay. Solve a problem. Explain a concept you’ve recently studied. I want to see how you think before I decide where to begin.”
You let out a quiet sigh, rubbing your forehead in frustration.
“You really couldn’t have just said that the first time?”
“I didn't think it required further explanation.”
You rolled your eyes, muttering something under your breath as you reached for the pen lying neatly beside the paper. His gaze never left you, making the room feel strangely smaller as you hesitated for a few seconds before finally putting the pen to the page and beginning to write.
“Done,” you said, setting the paper down in front of him before leaning back in your chair with a small, satisfied smile. “See? That didn’t take long.”
Nanami picked up the paper between his fingers and read over it in complete silence, his eyes moving steadily from one line to the next. His expression never changed, making it impossible to tell what he was thinking.
After a long moment, he placed the paper back on the desk.
He gave a small shake of his head.
“No,” he said simply. “Start over.”
Your eyebrows furrowed in confusion as you stared at him.
“...What do you mean, 'start over'?”
“Your explanations are vague, your reasoning is inconsistent, and you've made assumptions without supporting them.” He slid the paper back toward you. “You rushed through it because you wanted to finish quickly, not because you wanted to do it correctly.”
You looked down at the page before glancing back up at him, disbelief written all over your face.
“You’re seriously making me do the whole thing again?”
“Perhaps,” Nanami replied evenly, folding his hands together on the desk. “Try again anyway.”
You let out a long sigh, dragging the paper back toward you and rewriting it, this time adding more facts and slowing down so it actually looked like something he couldn’t immediately dismiss.
“Here,” you said, setting it down in front of him again with a slight frown, waiting for his reaction.
Nanami picked it up and read through it in silence, his eyes moving steadily across the page. This time, he lingered a little longer, as if actually considering the structure instead of just scanning for mistakes.
He exhaled quietly through his nose and placed it back on the desk.
“Better,” he said finally, “but you’re still rushing your reasoning. You’re listing information instead of explaining it.”
He leaned back slightly in his chair, picking up his coffee and taking a calm sip before continuing.
You groaned quietly and walked back to your desk, your shoulders slumped as your head hung forward in frustration.
You had been writing that same paper for what felt like an eternity now. Your hand was starting to ache, your focus was slipping, and the light outside had long since shifted into evening. The room felt quieter now, heavier somehow, and all you wanted was to be anywhere else but here.
“Here,” you said, placing the paper down in front of him with a small frown. Despite how tired you were, there was a hint of pride in your voice you had actually tried this time.
The moment the door clicked shut behind you, the room fell into silence again.
Nanami exhaled slowly, leaning back in his chair as his gaze drifted to the paper still sitting on his desk. His glasses were set carefully beside it, catching the last bit of fading light from the window.
For a moment, he didn’t move.
“Tch…” he muttered under his breath, almost like he was annoyed at something only he could understand.
But his eyes stayed on your work a little longer than necessary.
He reached out, straightened the page slightly, and finally leaned back again with a quiet sigh.
“Improvement,” he said to himself, almost dismissively.
Then, after a pause, he adds
It had been two weeks since your first session with Mr. Nanami.
Every afternoon after school, you found yourself making the same walk down the quiet hallway toward his office.
It hadn’t gotten any easier.
If anything, it had gotten harder.
The words “Try again.” had practically engraved themselves into your brain. No matter how many times you rewrote an assignment or corrected a mistake, he always found something else to improve.
Last night’s homework had taken you hours.
By the time you had finally finished it, the sun had nearly come up.
Needless to say, you were exhausted.
Today hadn’t helped, either.
You had overslept and arrived late to your first class, forgotten to eat breakfast, gotten your period halfway through the school day, and now the rain was coming down in sheets as you hurried across campus toward his office.
By the time you reached the door, your shoes were soaked and your uniform clung uncomfortably to your skin.
You knocked twice before quietly letting yourself inside.
Nanami glanced up from the paperwork on his desk, his eyes lingered on you for only a second longer than usual.
“You look tired,” he observed.
You forced a small shrug.
He didn’t comment further.
You obeyed, dropping your bag onto the floor beside the chair with a tired sigh.
“Now,” Nanami said, folding his hands together on the desk, “have you completed the assignment I gave you?”
“Yes, sir,” you replied, your voice rough from lack of sleep. “I stayed up pretty late finishing it.”
He gave a small nod and accepted the papers from your hands.
Silence settled over the room as he read.
Your heart pounded with every passing second.
Finally, he set the assignment back on the desk.
“This isn’t what I asked for.”
Your stomach dropped the moment the words left his mouth, and for a second you genuinely thought you had misheard him after spending nearly every waking hour making sure every detail of the assignment matched the instructions he had given you.
“What?” you asked quietly, your eyebrows pulling together in confusion as you searched his face for any sign that he was joking. “But... I followed everything you told me.”
“You followed the instructions,” Nanami corrected, carefully setting the assignment back onto his desk before folding his hands together. “However, you failed to understand the purpose behind them, and because of that, your work lacks the depth I was expecting.”
The words echoed in your head far louder than they should have, making every hour you had spent sitting at your desk the night before suddenly feel meaningless.
“Start over,” he continued without raising his voice, sliding the assignment back toward you. “I’ll give you another day.”
For several long seconds, you simply stared at the paper lying on the desk between you, your eyes tracing over the pages you had spent the entire night writing while trying to ignore how tired you were.
You had barely slept, you hadn’t eaten since lunch, and your entire body felt heavy with exhaustion, yet none of it seemed to matter because, somehow, it still wasn’t enough.
Your vision slowly blurred as tears gathered in your eyes, and before you could stop yourself, your lip began to tremble. You quickly raised a hand to wipe at your face, hoping he wouldn’t notice, but the tears came faster than you could brush them away, leaving dark streaks of mascara running down your cheeks.
Nanami’s expression changed almost imperceptibly, the slight furrow of his brows betraying a flicker of confusion as he watched you struggle to steady your breathing.
“I worked all night on that paper,” you managed to say between uneven breaths, your voice shaking with frustration as another tear slipped down your cheek. “Are you, are you serious?”
He cleared his throat quietly, the silence that settled between the two of you suddenly feeling heavier than either of you knew how to handle.
“I can give you another day if that’s what you’re worried about,” he said calmly, stepping a little closer before resting a careful hand on your shoulder.
“It’s not that,” you said, shaking your head as another tear escaped down your cheek. “It’s just... every time I hand you something, you throw it right back at me like nothing I do is ever good enough.
He let out a slow breath before giving your shoulder a light, reassuring pat.
“I understand why you’re frustrated,” he said quietly. “However, I won’t lower my expectations simply because the work is difficult. If I tell you to start over, it’s because I know you’re capable of producing something better.”
You sniffled, wiping at your eyes with the damp sleeve of your uniform.
“Clearly,” you muttered, your voice still thick with emotion.
Nanami adjusted his tie, his expression softening ever so slightly.
“Listen,” he began, “I’m not asking you to redo the assignment today.”
Your head lifted just enough to look at him.
“Go home,” he continued. “Get some rest, eat something, and clear your mind. You may finish the assignment another day.”
He paused before adding, “However... with the additional time, I will expect a higher standard than what you’ve shown me today.”
You looked up at him through watery eyes, your lower lip still trembling despite your efforts to compose yourself.
“Okay,” you said quietly, clearing your throat. “Thank you, Mr. Nanami.”
Another brief silence passed before his eyes drifted toward the rain-soaked window behind you.
“It’s pouring outside,” he observed. “Allow me to drive you home.”
He extended a hand toward you, offering to help you to your feet.
Heat rushed to your face.
“No, that’s okay,” you said quickly, pretending to busy yourself by slinging your backpack over your shoulder while deliberately ignoring his outstretched hand. “I can walk.”
“I insist,” Nanami replied without withdrawing his hand. “You’re already exhausted, and walking home in weather like this would be unnecessary.”
“Oh... okay. Well, thank you.”
You adjusted your skirt before following him out of the classroom.
Nanami grabbed his keys from the corner of his desk before switching off the lights. Once the room had gone dark, he locked the office door behind him and quietly led the way toward the faculty parking lot.
The rain had eased into a steady drizzle by the time you reached his car.
It was a sleek black Mercedes, polished so well that the parking lot lights reflected across its surface like glass.
For a moment, you simply stared.
How could someone on a teacher’s salary afford something like this?
Nanami noticed your hesitation but said nothing. Instead, he walked around to the passenger side and opened the door for you.
You climbed inside carefully, almost afraid to touch anything. The leather seats were spotless, the interior smelled faintly of coffee and cedar, and everything looked as though it had just come from the dealership.
Nanami settled into the driver’s seat before closing the door behind him.
“Seatbelt,” he reminded, nodding toward you as he fastened his own.
You quickly buckled yourself in.
“You may adjust the temperature if you’d like,” he said, setting his phone in the center console before turning to look at you. “Where do you live?”
You shifted awkwardly in your seat.
Growing up, your family had never had much money. The nicest car you’d ever ridden in belonged to a friend’s parents, and even that didn’t compare to his.
“Uhm, I live in the apartment complex near the school,” you replied quietly. “I can tell you when to turn.”
He turned his phone face down and pulled out of the parking lot, following your directions without another question.
The drive passed in comfortable silence, broken only by the steady rhythm of the rain against the windshield.
A few minutes later, he pulled into the apartment complex and parked near the entrance.
As you reached for the door handle, his voice stopped you.
His expression remained as composed as ever, but there was a quiet sincerity in his eyes as he gave your shoulder a light pat.
“You've been overworking yourself.”
A small smile tugged at your lips.
“I will,” you replied with a nod. “Thank you, Mr. Nanami.”
You stepped out into the cool evening air and closed the passenger door behind you. As you watched the black Mercedes disappear down the rain-soaked street, you couldn't help but think that, despite how impossible he could be, maybe Mr. Nanami wasn’t quite as cold as you’d first believed.
It was finally the weekend, and for once you actually allowed yourself to slow down instead of rushing through everything at the last minute, taking your time with the assignment he had given you and deliberately spacing out your work so that whenever your focus started to slip.
By the time Monday arrived and school had ended, you were actually proud of what you had managed to put together.
You made your way quickly through the school halls after class, your steps a little faster than usual as you stopped in front of his office door, hesitating for only a second before knocking and letting yourself inside.
Nanami looked up the moment you entered, his expression softening just slightly in recognition as he took a slow sip from the coffee mug resting in his hand, his posture remaining as composed and controlled as ever.
“I assume you’ve completed the work,” he said after a brief pause, one eyebrow lifting faintly as his attention settled fully on you.
“Yes, sir,” you replied quickly, adjusting your grip on the paper as you stepped forward.
He gave a small nod and gestured toward the chair in front of his desk, silently indicating for you to sit, and as you did, you couldn’t help but notice how the atmosphere between you had shifted slightly since the last time you were here, feeling less tense than before but still structured in a way that made you hyperaware of every movement you made.
The embarrassment from the previous session still lingered somewhere in the back of your mind.
You handed it over with a small, nervous breath that you tried to hide.
Nanami began reading immediately, his eyes moving across the page at a steady, deliberate pace, not rushing to judgment like before but instead actually taking in the structure of your thoughts.
When he finally set the paper down after a longer silence than usual, he gave a small, almost subtle nod that wasn’t dramatic or exaggerated.
“This is acceptable,” he said evenly. “There is a clear difference in how you’ve structured your reasoning this time.”
A smile broke across your face before you could stop it.
“Thank you, Mr. Nanami!” you said quickly, the relief obvious in your voice.
He gave a soft hum in response, already shifting his attention briefly back to the paper as.
“Have you been taking care of yourself as well?” he asked after a moment, his eyes briefly flicking to his watch before returning to you.
“Yes,” you answered without hesitation.
You hesitated for only a second, shifting slightly in your seat as you considered your answer before finally letting out a small, honest shrug as you spoke, your voice quieter this time as the exhaustion from the day caught up to you again.
“Most of the time, I didn’t really eat today though. It was just a busy day.”
Nanami exhaled softly through his nose, a subtle sign of concern rather than frustration, as he set the paper fully down and pushed himself up from his chair.
“Then come with me,” he said simply, already reaching for his coat.
“Huh?” you blinked, caught off guard by the suddenness of it.
“It’s a small celebration,” he added after a brief pause, adjusting his tie, “As people tend to call it.”
“Oh, I don’t know, I should probably just head home,” you started, awkwardly rubbing the back of your neck as you tried to think of a way to politely refuse, “I don’t really have much money right now, so–”
“I will be paying,” he interrupted immediately, his tone still even but firm enough that it left no room for argument.
He picked up his coat and turned toward the door, already signaling that the decision had been made.
“No arguments,” he added simply as he opened the door, already stepping aside for you to follow.
You nodded quickly and walked after him, hurrying slightly to keep up as you both made your way toward the parking lot where his car was waiting.
“Thank you again, Mr. Nanami,” you said quietly, still a little unsure of yourself after everything that had happened earlier.
He glanced at you as you reached the passenger side, his eyes briefly tracking your movements as you buckled your seatbelt before he stepped around to the driver’s side and got in.
“Kento,” he said after a moment, adjusting the cuff of his sleeve as he started the car, his tone calm but firmer than before. “Call me Kento. And I can see you’re learning.”
Your fingers paused slightly on the seatbelt.
“Oh, yeah,” you said quickly, letting out a small, nervous laugh as you tried to recover from the sudden shift in familiarity.
After a short drive, Kento pulled into the parking lot of a small café tucked between several shops, shutting off the engine before glancing over at you.
“We’re here,” he said simply, nodding toward the building through the windshield. “They serve decent food.”
You looked out the window, taking in the warm lights glowing from inside before quietly nodding.
The two of you stepped inside together, the soft chatter of customers and the smell of fresh coffee immediately replacing the cool air from outside. Kento waited patiently as you looked over the menu hanging above the counter, noticing how long you lingered on the prices instead of the food itself.
“Order whatever you’d like,” he said, adjusting his tie as though it were the most ordinary thing in the world. “Don’t concern yourself with the cost.”
You hesitated, still staring at the menu.
“Can I just get one of the sandwiches?” you asked quietly, glancing over at him. “I don’t want you spending too much on me.”
Kento looked at you for a brief moment before turning back toward the cashier.
“Two sandwiches, please.”
Without another word, he pulled a sleek black credit card from his wallet and paid before you even had the chance to object.
“You really didn’t have to.”
“I know,” he replied calmly, sliding the card back into his wallet. “I wanted to.”
A few minutes later, the order was ready.
You thanked the cashier, carefully taking the paper bag into your hands before following Kento back outside and into his car.
Once the engine started, he glanced over at you for a moment before pulling out of the parking lot.
“‘I’ll take you home,” he said. “That way you can enjoy your meal while it's still warm.”
You nodded, resting the bag carefully in your lap.
“Thank you, Kento,” you said with a small smile, tucking a few loose strands of hair behind your ear. “I really appreciate it.”
“There’s no need to thank me,” he replied, his eyes remaining on the road as he spoke. “I’d rather see you taking proper care of yourself than skipping meals.”
As the car came to a stop at a red light, he reached over and gave your arm a light, reassuring pat before returning his hand to the steering wheel.
Heat immediately rushed to your cheeks as you quickly turned your head toward the window, hoping he wouldn’t notice the way your face was betraying you.
“Yes,” you mumbled, smiling to yourself despite your embarrassment. “I will.”
“Bye. I will see you at school tomorrow,” he said calmly, adjusting his glasses as he glanced briefly in your direction.
You waved lightly before stepping out of the car and gently shutting the door behind you, standing there for a moment as you watched the black vehicle idle at the curb.
A small smile lingered on your face even after he drove off.
He wasn’t as bad as you thought.
In fact, maybe he was even kind.
You shifted the paper bag in your hands, the warmth of the food grounding you slightly as you turned toward your apartment, the thought of everything that had happened over the past few weeks lingering quietly in your mind.
You had worked on the assignment harder than you ever had before, not just because you were afraid of his criticism anymore, but because somewhere along the way, you actually wanted him to see that you could do better.
The next morning, you didn’t show up to school.
You weren’t entirely sure how it had happened, whether it was exhaustion, nerves, or something quieter and harder to name, but the idea of walking back into the building and sitting through another day felt heavier than usual, like something in your chest tightened every time you even thought about it.
Of course, part of you still wanted to see Nanami.
That thought alone was what made everything more confusing.
So you told your mom you weren’t feeling well, staying in bed long enough for her to leave for work before quietly slipping out of the house with no real plan except to avoid thinking too much about anything at all.
You ended up walking for a while, letting your feet carry you wherever they wanted until the weight in your mind eased just enough to breathe again. Eventually, you stopped at a small shop, grabbing a drink and something to eat, trying to convince yourself that today didn’t need to mean anything at all.
But as you continued down the sidewalk, drink in hand, lost in your own thoughts, you caught sight of something that made your stomach drop slightly.
Your steps slowed immediately.
With a quiet gulp, you instinctively pulled your hood up, lowering your head as you continued walking, suddenly very interested in the cracks in the pavement beneath your feet as you tried your best to act like you hadn’t seen anything at all, hoping, quietly, desperately, that he hadn’t seen you either.
“Why are you not at school?” a familiar voice said from behind you.
You let out a quiet sigh before slowly turning around, hesitating for only a second before pulling your hood down and meeting his eyes.
“Just, wasn’t feeling like it,” you admitted, rubbing the back of your neck, trying to sound casual.
Nanami studied you for a moment, his expression calm.
“Is there a particular reason?” he asked.
“No,” you said quickly, shaking your head.
“Is someone bothering you?”
“No, sir, I promise everything is fine,” you said quickly, forcing a nervous smile.
Nanami paused for a beat longer than usual before giving a small nod. “Alright.”
The word came out calm, but not fully satisfied.
He glanced at the time on his watch before looking back at you.
“Would you like me to drive you home?” he asked evenly. “Or I can take you to school. We can continue your session as planned.”
You hesitated, shifting your weight slightly as you looked away.
“No, it’s fine,” you said quietly, shaking your head again. “I’m okay.”
Nanami exhaled softly through his nose, adjusting his cuff with slow, deliberate movements before looking back at you.
“You’re going to get back in the car,” he said simply.
Your eyes widened slightly.
“What?” you blinked, caught off guard.
He tilted his head just a fraction, his gaze steady but not harsh, more like he had already decided this conversation was finished before it had properly started.
“You’re not going to stay out here in the cold while skipping school and pretending you’re fine,” he continued evenly, as if stating something obvious. “Get in the car.”
Heat crept up your neck anyway, mostly from the fact that he wasn’t budging even slightly, just standing there with his hand resting loosely at his side like he had all the time in the world to wait for you to listen.
“I said I’m okay,” you tried again, though it came out weaker this time, your grip tightening slightly around your drink.
Nanami looked at you for a moment, then let out a quiet sigh, almost patient.
“Get in the car,” he repeated. “Or I’ll start assuming you need supervision again.”
Your face warmed instantly, and you quickly looked away as if the sidewalk had suddenly become extremely interesting.
You settled back into the passenger seat, letting the door close behind you with a soft thud as you adjusted your jacket zipper out of habit, your fingers lingering on the fabric a little longer than necessary as the weight of everything from earlier slowly began to settle in your chest.
“Sorry, Kento,” you murmured after a moment, still keeping your gaze lowered as you tried to focus on anything except how aware you were of him sitting right beside you.
“It’s alright,” he replied calmly after starting the car, as he guided the vehicle smoothly onto the road, “Just make sure next time you actually get in when I tell you to. I’d rather you not stand out in the cold like that again.”
“Mm,” you hummed in response, nodding slightly even though you still weren’t fully looking at him, your attention fixed on your hands instead as you tried to settle the lingering embarrassment from earlier.
A quiet silence stretched between you for a moment before his voice came again, quieter this time, more measured, like he was choosing his words with a little more care than usual.
“Is something still bothering you?” he asked, his eyes flicking briefly toward you before returning to the road. “You said you were fine earlier, but that doesn’t seem entirely accurate.”
You hesitated for a second longer than you meant to, your fingers curling lightly against your sleeve before you finally let out a small breath, your voice softer now as you admitted it out loud instead of keeping it in your head.
“I’m okay,” you said quietly, “I just feel embarrassed. For crying in your office.”
The words hung in the air for a moment, and instead of immediately responding like he usually would, Nanami stayed quiet just long enough for the silence to feel noticeable rather than empty, his expression unreadable as the car moved steadily through the street.
Then, finally, he spoke again.
“There’s no reason to be embarrassed,” he said simply.
You shifted slightly in your seat, still looking away as your cheeks warmed faintly.
“I was strict with you because I know what you’re capable of,” he continued after a brief pause, one hand resting on the wheel while the other adjusted his cuff in that calm, habitual way of his. “Not because I think less of you.”
That made your chest tighten in a different way, quieter but harder to ignore, and before you could think too much about it, he glanced at you again, this time holding the look for just a moment longer than necessary.
“I’m sorry,” he added, voice slightly softer now. “If I was too harsh.”
You blinked, caught off guard by that.
“…It’s okay,” you murmured, finally glancing up at him for the first time since getting in the car, your voice quieter as you added, “I just didn’t expect you to care about it like that.”
For a brief moment, Nanami didn’t respond.
The car slowed slightly at a red light, and the quiet inside it deepened in a way that made everything feel more still, more focused, like even the world outside had dulled just a little.
Then he turned his head just enough to look at you properly, his expression still composed, but his attention fully on you now in a way that felt impossible to ignore.
“You misunderstand me sometimes,” he said calmly, his voice even, measured, deliberate.
Before you could fully process what he meant, he reached over, and gently brushed his fingers along your cheek, just enough to guide your face up slightly so you were no longer looking down at your lap.
The touch was brief, careful, almost absent-minded in how natural it felt for him, but it lingered just enough to make your breath catch in your throat.
“You should stop apologizing for things you didn’t do wrong,” he said quietly, his hand withdrawing just as smoothly as it had come, returning to the steering wheel as if nothing unusual had happened at all.
But the space between you didn’t feel the same anymore.
The rest of the drive passed in silence, the kind that should have felt normal by now but somehow didn’t, because this time you were painfully aware of every second that went by without either of you mentioning what had just happened, while Nanami continued driving as if nothing had shifted at all.
You couldn’t help but wonder if he acted like this with everyone, if moments like that meant something to him at all, or if it was just another passing interaction in a long day he would barely think about later.
The car eventually slowed as it pulled up in front of your apartment.
“See you tomorrow,” he said simply, already leaning over to open your door for you. “Show up.”
“Thanks again, Kento,” you said with a small grin as you unbuckled your seatbelt, trying to act normal even though your chest still felt slightly tight in a way you couldn’t fully explain.
He gave a small nod in response as you stepped out of the car.
And just like that, the moment was over, at least on his side.
You’d spent longer than usual in front of the mirror, nicer makeup, smooth legs, and lip gloss reapplied twice just to get the shine right. You even chose the shorter skirt, the one you usually saved for days you wanted to feel a little braver.
Before leaving your room, you sprayed perfume on your neck and wrists, the scent blooming softly as you exhaled. Just in case.
By the time you reached Nanami’s classroom, your heart was already beating a little too fast. You knocked once, then opened the door without waiting.
Nanami looked up from his desk. The top button of his shirt was undone, revealing a glimpse of collarbone and the sharp line of his chest. Your gaze flickered there for half a second before you forced it back to his face.
You tried to walk normally as you approached, painfully aware of how the shorter skirt moved against your thighs. Did he notice? You couldn’t tell. His expression remained calm, unreadable as always.
You sat down in the chair across from him, smoothing the fabric over your lap.
“Thanks again for driving me home the other day,” you said, placing the small paper bag on his desk. “I made you a sandwich. It’s nothing special, but, for your help.”
Nanami’s eyes flicked from the bag up to you. For a moment, his gaze lingered on your face, then briefly lower, before returning to your eyes. He raised a brow, the corner of his mouth twitching in what might have been faint surprise.
“Oh. Thank you,” he said, voice low and even as he accepted the bag. His fingers brushed lightly against yours as he took it. “That was thoughtful.”
“Mhm,” you nodded, suddenly unable to think of anything else to say. Heat rose to your cheeks.
“So, may I see your work?” Nanami asked, one brow lifting slightly.
You handed him the paper, fingers brushing his as you did. Your heart hammered against your ribs while you watched him begin to read.
For a few seconds, everything was quiet. Then you noticed his eyes drifting. Not just across the lines you’d written, but occasionally lower, tracing the bare stretch of your legs beneath the shorter skirt. His throat bobbed with a visible swallow.
You bit the inside of your cheek to hide a small, nervous smile.
Nanami set the paper down carefully, his usual composure cracking just enough for you to notice. He cleared his throat.
“You’re improving,” he said after taking another look at your work, his eyes lingering on the page for a moment before he looked back up at you. “I’m proud of the progress you’ve made. You’ve been putting in the effort, and it’s beginning to show.”
“Thank you, Mr. Nanami,” you replied, rubbing the back of your neck awkwardly as you shifted your weight in your chair, suddenly finding it much harder to meet his eyes than you usually did.
Somehow, the confidence you’d spent all morning trying to build had completely disappeared the moment you found yourself sitting across from him.
Nanami glanced toward the rain-speckled window beside his desk, quietly watching the steady drizzle that had begun to fall before returning his attention to you.
“You’ve been working yourself quite hard these past few weeks,” he said calmly, folding his hands together for a brief moment. “I think you’ve earned a break. I won’t be giving you an assignment today.”
Your eyebrows lifted in surprise.
“However,” he continued, “I’d like to drive you home. It’s raining again, and I’d rather not have you walking in weather like this.”
A small smile spread across your face before you could stop it.
“Oh... okay. Yes, thank you.”
Nanami stood from his chair, slipping his keys into one pocket before picking up the neatly folded jacket resting over the back of it.
As you stood to gather your things, he stepped beside you and, without making a fuss over it, gently draped the jacket across your shoulders, taking a brief moment to straighten it so it wouldn’t slide off before withdrawing his hands again.
“Here,” he said simply. “I’d rather you didn't get sick.”
The warmth of the jacket settled around you almost immediately, carrying the faint scent of coffee and cedar, and before you realized it, heat had rushed to your cheeks.
You quietly adjusted the sleeves around your arms, smoothing your skirt almost absentmindedly as you tried very hard to ignore the way your heart had suddenly begun beating just a little faster.
Once you two were in the car he began to drive you home, he had practically memorized it.
The car came to a stop in front of your apartment building. You unbuckled your seatbelt with a quiet sigh, turning to look at him.
“Thank you, Kento,” you said softly, a small smile tugging at your lips.
For a moment, neither of you moved. The air between you felt thick, heavy with everything that had been building for weeks. Before you could overthink it, you leaned across the center console and pressed your lips to his.
For a breathless second, he didn’t respond. Then, with a low sound in the back of his throat, his hand came up to the back of your neck, fingers sliding into your hair as he kissed you back, harder, deeper. His tongue brushed against yours, warm and deliberate, stealing the air from your lungs.
When he finally pulled away, a thin string of saliva connected your lips for a moment before breaking. You wiped your mouth with the back of your hand, cheeks burning.
“I… sorry,” you whispered, voice shaky.
Nanami’s breathing was heavier than usual. He stared at you for a long moment, jaw tight, clearly fighting for control.
“Wait,” he said, voice rough and low. “Let me walk you inside.”
You nodded, heart racing, and stepped out of the car. Nanami followed. The short walk to your apartment door felt endless, the night air cool against your flushed skin. Neither of you spoke. The tension from the kiss still crackled between you.
When you reached the doorstep, you turned to face him. Before you could say goodnight, Nanami stepped closer. His thumb gently brushed across your bottom lip, wiping away the faint trace of gloss.
“May I?” he asked quietly.
This time he didn’t hesitate. His hand cupped the back of your neck as he pulled you into a deeper kiss. His mouth was warm and insistent, tongue sliding against yours with a hunger that made your knees weak. You moaned softly into his mouth, fingers gripping the front of his shirt. His other hand trailed down your side, settling firmly on your hip, pulling you closer until your bodies pressed together.
The kiss grew messier, more desperate. He tilted his head, tasting you thoroughly, a low groan vibrating in his chest when your tongue brushed his. His fingers dug into your hip, the other hand threading through your hair. For a few heated moments, the usually composed Nanami let himself indulge, kissing you like he’d been thinking about it far longer than he’d ever admit.
When you finally broke apart for air, both of you were breathing hard. Your lips felt swollen, and a thin string of saliva still connected you for a second before breaking.
You looked up at him, cheeks burning, courage and desire mixing together.
“…Do you want to come inside?” you whispered.
For a long moment he didn’t answer. His thumb continued to stroke your hip almost absentmindedly, his jaw tight with restraint.
He exhaled slowly through his nose, clearly fighting with himself.
“I shouldn’t,” he said, voice strained. “This... crosses every professional boundary.”
But even as he said it, he didn’t step back. His forehead rested gently against yours, eyes closed like he was trying to steady himself.
You waited, barely breathing.
Finally, he opened his eyes again. His voice was quieter, almost reluctant.
You smiled, a mix of nerves and excitement fluttering in your chest as you grabbed his hand and gently pulled him inside. The door clicked shut behind you, sealing the two of you in the quiet of your apartment.
You barely had time to kick off your shoes before your lips crashed together again. The kiss was urgent, breathless. Nanami shrugged out of his jacket with your help, letting it fall to the floor without care. His hands found your waist as you stumbled together toward the couch, mouths never fully parting.
You pushed him down onto the couch and climbed into his lap, fingers already working on his tie. You yanked it loose with shaky hands and tossed it aside, then fumbled with the buttons of his shirt. A soft, frustrated sound left you.
Nanami’s large hands covered yours, steadying them. “Easy,” he murmured against your lips, voice rough. He helped you undo the buttons, then rolled his shoulders to let the shirt slide off, revealing the firm, toned chest you’d only caught glimpses of before.
Your hands roamed over his warm skin immediately. He exhaled sharply at your touch.
He didn’t waste time. His fingers moved to your blouse, unbuttoning it with far more patience and precision than you had managed. Once it was open, he pushed it off your shoulders, dropping it somewhere behind the couch.
For a long moment, Nanami just looked at you, his gaze dark and heavy as it traced over your chest and bare skin. His throat bobbed.
“You’re beautiful,” he said quietly, almost reverently. His thumb brushed across your bottom lip, eyes locked on yours. “Open for me.”
Your lips parted obediently. He slipped his thumb into your mouth, and you closed around it, sucking gently while holding his gaze. A low groan rumbled in his chest. His free hand slid up your side and cupped your breast, thumb brushing over your nipple in slow, deliberate circles.
“Good girl,” he praised, as he slowly slipped his thumb out of your mouth, a thin string of saliva connecting it to your lip for a moment.
His hands moved to your back. With practiced ease, he unhooked your bra and let it fall away. Your breasts spilled free, he took in the sight of you. He let out a slow, controlled breath, like he was trying to keep himself in check.
“You’re sure about this?” he asked quietly, even as one hand cupped your breast, thumb brushing over your hardened nipple. “We can stop anytime.”
You nodded quickly, breath shaky. “I want this, I want you.”
That seemed to be all the permission he needed.
He leaned in, capturing your lips again in a deep kiss while his hands explored your body. His mouth soon left yours, trailing hot kisses down your neck and collarbone until he took one of your nipples into his mouth, sucking and flicking his tongue over it. You moaned, arching into him, fingers threading through his neatly styled hair.
Nanami groaned against your skin. “So sensitive,” he murmured.
He shifted you both so you were lying back on the couch, his body hovering over yours. His hand slid down your stomach, fingers slipping under the waistband of your skirt and panties. He rubbed slow, deliberate circles against your clit, watching your face the entire time.
“You’re already so wet,” he said, voice husky. “Have you been thinking about this?”
You whimpered, nodding. The pleasure was overwhelming, new, and intense.
He pushed one thick finger inside you carefully, then another, stretching you gently while his thumb continued teasing your clit. “Relax for me,” he instructed softly, kissing the corner of your mouth. “I need you to be ready.”
You were panting, hips moving against his hand on their own. The stretch burned slightly, but the pleasure was stronger. When he curled his fingers just right, you cried out.
“That’s it,” he praised, voice steady and commanding. “Let me hear you.”
After a few more moments of patient preparation, he withdrew his fingers. He stood just long enough to remove the rest of his clothes, revealing his toned body and his hard, impressive length. You felt a flicker of nervous excitement.
“I’ll go slow,” he promised, settling between your thighs again. He rubbed the head of his cock against your slick folds, teasing you. “Breathe, sweetheart.”
You felt pressure as he began to push in, slow, inch by inch. It stung, a deep stretch that made you gasp and grab his shoulders. Nanami immediately stilled, leaning down to kiss you softly.
“You’re doing so well,” he murmured against your lips. “Taking me so good for your first time.”
He stayed buried inside you for a moment, letting you adjust, whispering quiet praises and kissing your neck until the discomfort eased. Only then did he start moving, slow, deep thrusts that gradually became more confident.
His hand pinned one of your wrists above your head as his pace increased, still controlled but clearly holding back less now. Every thrust drew moans and whimpers from you. He watched your face the entire time, eyes intense.
“Look at me,” he ordered gently when your eyes fluttered shut.
You obeyed, and the intensity of his gaze made everything feel even more overwhelming.
Nanami kept his thrusts deep and controlled, dragging against every sensitive spot inside you. You were shaking, whimpering, right on the edge again when he suddenly slowed down, leaving you painfully close.
“Not yet,” he murmured, voice low and steady. “Hold it for me.”
You let out a frustrated sob as he edged you, pulling back just as the pleasure started to crest. Tears of overwhelming sensation pricked at your eyes.
When he finally started moving again, faster, harder, your body couldn’t handle it anymore. Every thrust felt electric. You were too sensitive, too full, too much.
“Poor baby,” Nanami cooed, voice dark with lust as he watched your tear-streaked face. “So overstimulated already, and you still haven’t cum.”
His words made you clench hard around him. He rubbed your clit in tight, merciless circles while thrusting deep, not giving you any mercy this time.
“Please, Kento, I can’t!” you cried out, voice breaking.
“You can,” he said firmly. “Cum for me. Now.”
The orgasm slammed into you violently. You screamed, back arching sharply off the couch as intense pleasure ripped through your body. Your walls pulsed and fluttered wildly around him, thighs shaking uncontrollably. The overstimulation made the climax feel endless, wave after wave crashing over you until you were gasping and sobbing with it.
Nanami groaned deeply at the feeling of you squeezing him so tightly. He fucked you through every second of it, drawing out your pleasure until you were a trembling, whimpering mess beneath him.
Only then did he let himself go.
With a few final, powerful thrusts, he buried himself deep inside you and came hard, groaning your name as he spilled inside you, hips jerking against yours.
Nanami stayed buried inside you for a long moment, both of you breathing hard. Slowly, he pulled out, careful not to hurt you. You winced slightly at the sudden emptiness and the soreness that was already settling in.
He disappeared into your bathroom for a moment and returned with a warm, damp cloth. Gently, almost reverently, he cleaned between your thighs, his touch feather-light.
“Poor thing,” he said softly, pressing a kiss to your inner thigh. “You took me so well for your first time.”
When he was done, he pulled you into his arms on the couch, wrapping you up against his chest. One large hand stroked slowly up and down your back while the other cradled the back of your head. You buried your face in his neck, still trembling from the intensity of everything.
“You did so good,” he whispered against your hair. “I’m proud of you.”
The praise made your chest feel warm. You clung to him tighter, legs tangled with his. For a while, the only sound was your breathing and the steady beat of his heart.
As you started drifting off in his arms, you felt him press one last kiss to your forehead.
“Rest now,” he murmured. “I’ve got you.”
