You sank deeper into the dorm couch, your socks half sliding off your feet as you tucked them under you. The living room lights were dim, just the warm glow from the lamp in the corner and the TV screen, where some random variety show played with low volume. The real sound in the room came from your phone speakers.
âPretty woman~â Mingyuâs voice flowed out, followed by S.Coupsâ part, and you hummed along under your breath, mouthing some of the lines you knew too well. Your fingers scrolled automatically, thumb gliding down the Tumblr app as you read.
Your eyes stayed glued to the screen.
His hand brushed your waist as he leaned inâ
You swallowed and blinked fast, feeling your face heat up even though nobody was paying you real attention. Or so you thought.
From the other side of the room, Lee Know paused mid-bite of his chips. He watched you for a second. You were way too still. No complaining, no talking, no reacting to the show. Just⊠phone, screen, music, humming, and that slightly stunned look on your face.
âWhy do you look like youâre studying for an exam?â he asked suddenly.
You flinched. âIâm not.â
Eight heads turned in your direction. You realized too late that you had just made yourself suspicious.
Bang Chan, sitting on the floor with his laptop, glanced up. âWhat are you doing, Y/N?â
âNothing,â you said quickly.
That was the wrong word. The deadly word.
Hanâs eyes narrowed. âOho. âNothingâ is what people say when theyâre definitely doing something.â
Hyunjin, sprawled on the rug, rolled onto his stomach, chin in his hands. âAre you texting someone?â
I.N gasped. âIs it a boyfriend?â
Your nose wrinkled. âNo!â
âGirlfriend?â Felix added, grinning.
âNo!â you repeated, louder this time. âItâs just⊠some stuff.â
Lee Know stood up, wiping his fingers on his sweatpants. âStuff like what? Youâve been staring at your phone for twenty minutes without blinking. That canât be normal.â
You forced your shoulders to stay relaxed, your fingers tightening around your phone. âIâm just reading.â
Seungmin looked over from the armchair. âReading what?â
You stared at him, your mind scrambling for something normal. âNews,â you lied. It came out too fast.
Han snorted. âYeah, sure. Youâre humming to âPretty Womanâ while reading the news? What, is Mingyu the weather forecast?â
You bit your lip. On the screen, you saw the line:
âCoupsâ fingers trailed along your armâŠâ
You locked your phone so fast you almost dropped it.
Lee Know narrowed his eyes with the energy of a cat who had just seen a red dot move. âShow me.â
âNo.â You hugged your phone to your chest.
The room got louder in an instant.
âWhat do you mean, ânoâ?â Chan asked, his leader voice waking up.
âWhat the fuck? It's my phone,â you shot back.
Felix scooted closer on the other side of the couch. âAre you watching something weird?â
You could feel your soul leave your body. âWhy would you say it like that?â
Hyunjin pointed dramatically. âEveryone, sheâs suspicious. Confiscate the device.â
âGod...this isn't school,â you said, glaring.
But they were already moving. Lee Know came around the coffee table. Han crawled over the rug like some kind of gremlin. I.N perked up, excited at the hint of chaos.
You shot up from the couch. âDonât touch my phone!â
Felix laughed. âNow we have to see.â
You backed away, holding your phone behind you. âItâs private and none of your business!â
âThen you shouldâve stayed expressionless,â Seungmin said, standing too. âYou look like someone who just read something they shouldnât have.â
You hated how accurate that was.
Lee Know reached you first, hand out. âCome on, just show me. Iâll tell them if itâs bad.â
âOh, thatâs worse,â you said. âAbsolutely not.â
You stepped away from him, almost tripping over Hyunjin, who tried to grab your wrist from below.
âTraitors, all of you!â you yelled, dancing out of reach.
âY/N, stop running,â Chan said, standing up slowly. His voice was calm, but you heard the older-brother tone in it. âYouâre going to fall.â
âIâd rather fall than show you my phone.â
That did not help your case.
Han made a fake lunge, and you dodged, laughing nervously. Your heart beat faster, not just from the running but from the panic that someone might see the words âS.Coups x Reader â Rated Tâ on your screen.
âIs it at least legal?â I.N asked as he tried to move around to cut you off.
âOh my god, yes, itâs legal!â you snapped. âIâm not a criminal, Iâm justââ
You cut yourself off before you confessed anything.
Lee Know stopped and tilted his head. âYouâre just⊠what?â
âNothing!â you yelled again.
Chan sighed and rubbed his face. âY/N.â
You stuck your tongue out at him and backed toward the hallway.
That was your mistake.
You had forgotten that Bang Chan had years of practice dealing with eight chaotic members, plus a younger sibling. You had forgotten he was fast when he wanted to be.
You took one more step back, felt the slight shift in the air, and before you could react, Chanâs arm came around from behind you. He hooked his hand over your wrist and gently but firmly pulled your phone out of your grasp.
âNo!â you shrieked. âNo no no noââ
Too late.
He took a step back, already tapping the screen awake. You watched his face as your lock screen disappeared and the last opened page came up.
Time froze.
You saw his eyebrows draw together. His eyes flicked over the title.
âPretty Woman â S.Coups x Reader (College AU)â
Chan stared for one second.
Then another.
Then his whole expression changed.
âOh myââ He cut himself off, his eyes widening as he scrolled a little by accident. âOkay, what the- No. No, no, noââ
âGive it back!â you lunged, but Lee Know held your shoulders, half laughing, half curious.
âWhat is it?â Han demanded, bouncing on his toes.
Chan looked horrified. âItâs⊠itâs⊠itâs a fanfiction.â
Hyunjin gasped dramatically. âOh? Thatâs not so bad.â
Chan shook his head. âItâs a fanfiction about her and S.Coups.â
The room exploded.
âWHAT?â
âHUH?â
âEXCUSE ME?â
âSEVENTEEN S.Coups?!â Felixâs eyes almost popped out.
You buried your face in your hands and groaned loudly. âWhy would you say it out loud?â
Seungmin let out a disbelieving laugh. âYouâre reading S.Coups x Reader fanfic in our dorm?â
âWhile listening to his song,â Lee Know added. âThatâs dedication thoâ
I.N blinked rapidly. âWait, so you and S.Coups⊠like⊠in the story⊠are⊠likeâŠâ
âStop talking,â you begged. âPlease.â
Chan held your phone out like it was contaminated. âItâsâ itâs so weird. Why would you read this? Why would you imagineâ?â He broke off, visibly disgusted. âUgh.â
You snatched the phone from his hand before he dropped it. âBecause Iâm a normal human being with a crush,â you snapped.
The room went quiet.
You hadnât meant to say it that bluntly, but it was out. You clutched your phone to your chest, cheeks on fire, and stared at them.
Felix was the first to speak. âSo you⊠like him?â
You rolled your eyes. âWell, Iâm not reading fanfiction about him because I hate him.â
âBut heâs older,â I.N said, frowning. âAnd heâs, like⊠S.Coups.â
âAnd youâre pretty young,â Chan added, a stubborn edge in his voice.
You stared at him. âIâm twenty-one, Chan.â
âExactly,â he said. âToo young.â
You laughed once, disbelief spilling out. âWow. Okay. So when you were twenty-one, you were traveling, training, dealing with everything, but Iâm too young to have a crush on an idol?â
âThatâs different,â he said quickly.
âHow?â you demanded.
âBecause youâre you,â he said.
You threw your free hand up. âAre you fucking kidding me!â
Han looked between you two like he was watching a ping-pong match. âOkay, wait, wait. Letâs⊠letâs breathe. Y/N, you have a crush on S.Coups?â
You crossed your arms. âYes. Heâs hot. And amazing. And frankly, you guys could be a little less bitchy about it.â
Hyunjin choked on his drink. âYou just called him hot in front of your brother.â
Chan clapped his hands over his ears. âI didnât hear that. I refuse.â
Lee Know smirked. âI heard it clearly.â
Felix giggled. âSame.â
Seungmin leaned back in the armchair. âSo thatâs why you always watch Seventeen clips when you think no oneâs looking.â
You glared at him. âI never said I was subtle.â
âOkay, butâŠâ I.N looked worried. âAre you sure? Like⊠idol crushes are dangerous. They make you weird.â
âToo late for that, I am already weird,â you said flatly.
âThatâs true,â Lee Know agreed.
You ignored him.
Chan stepped closer, his brows furrowed. âI just⊠I donât like it.â
Your jaw clenched. âHuh?â
He hesitated, looking for the right words. âHeâs a grown man. An idol. Youâre my little sister.â
You exhaled sharply. âThere it is. Little.â
âYou are my little sister,â he insisted.
âIâm an adult,â you shot back. âYou know that, right? Like, legally. Emotionally. Mentally. Okay, maybe not mentally all the time, but still.â You gestured at him with your phone. âYou canât freeze me at age twelve forever just because it makes you feel better.â
Felixâs smile faded slightly as he watched you. The others exchanged glances.
Chan opened his mouth, closed it, then opened it again. âIâm not trying to freeze you,â he said more quietly. âI just⊠donât like the idea of some guyââ
âHe doesnât even know I exist,â you interrupted. âItâs fanfiction, Chan. Words on a screen. You think S.Coups is going to appear in the dorm and sweep me away because I read a Tumblr fic?â
Han raised his hand. âPlot twist: he does.â
Hyunjin elbowed him. âNot helping.â
You ran a hand through your hair. âI get that you want to protect me. All of you do. But itâs annoying when you act like Iâm a baby who canât handle a crush. Iâm twenty-one. I can find people attractive without spontaneously combusting.â
âYou say that,â Seungmin muttered, âbut look at your face. Youâre literally combusting right now.â
You pointed at him. âThatâs embarrassment. Itâs different.â
Chan looked at you, his expression softening just a little. âWe just⊠donât want you to get hurt.â
âHow am I getting hurt from reading fanfic?â you asked. âItâs not like Iâm dating him. I just like him. Heâs talented, heâs kind, he has that leader vibeââ you paused, side-eyeing Chan. âWhich you should respect, by the way, leader-to-leader.â
Chanâs jaw tightened. âI respect him as an artist.â
âBut not as someone I could maybe⊠I donât know⊠admire?â you said.
âYou can admire him,â Chan said quickly. âFrom far away. Very far away.â
You squinted at him. A little spark of mischief flickered in your chest, pushing against the frustration. You tilted your head, then decided to go for it.
ââFar away,â huh?â you said slowly. âAbout⊠fanmeeting-distance?â
Felix blinked. âWhat does that mean?â
You smiled, innocent and evil at the same time. âI mean, like⊠send-off distance.â
The room fell silent.
Chanâs eyes narrowed. âWhat did you do?â
You slipped your phone into your pocket and shrugged casually. âI might have⊠booked a send-off with him.â
Time stopped AGAIN.
âWhat?â Chanâs voice jumped an octave.
âYOU WHAT?â Han yelped.
Hyunjin sat up so fast his hair flew. âWhen? How? Why didnât we know?â
âI bought a ticket like a normal fan,â you said, savoring every second of their reactions. âUsed my own grown up money. Iâm allowed.â
Felix covered his mouth with both hands, eyes sparkling. âYouâre going to meet him?â
âYes,â you said, holding Chanâs gaze. âFace to face.â
I.N looked both impressed and horrified. âNo way.â
Lee Know shook his head slowly. âYouâre brave. Or insane. Maybe both.â
Chan stared at you like you had just told him you planned to move to Mars. âYou canât go.â
You snorted. âOh wow...Watch me.â
âY/N,â he said, his voice low.
You met his eyes without flinching. âI already paid. Itâs done.â
He looked at the others for backup.
âGuys,â he said, helpless. âSay something.â
Han drew a circle on the rug with his finger. âI mean⊠sheâs twenty-one. Fans younger than her go to these things all the time.â
Hyunjin nodded slowly. âYeah. And itâs not like sheâs going alone at night in some shady alley. Itâs a normal event. Staff, security, all that.â
Seungmin shrugged. âAnd itâs S.Coups, not some random creep.â
âThat doesnât make me feel better,â Chan muttered.
Felix leaned forward. âIâll go with her,â he offered. âIf our schedule lets us. Then sheâs safe and you can stop freaking out.â
Your heart squeezed. âLixâŠâ
I.N raised his hand. âIâll go too. I want to see what he looks like in real life. I mean, Chan-hyung complains, but he always says good things about Seventeen as sunbaenims.â
Chan shot him a betrayed look. âWhose side are you on?â
âY/N's obviously,â I.N said without hesitation.
Lee Know smirked. âHonestly, I kind of want to see Chanâs face when she stands in front of S.Coups. That alone is worth supporting her.â
You snorted. âThank you, I think.â
Chan looked like the ground had opened under him. âYou guys are no help.â
âYouâre outvoted, hyung,â Han said cheerfully. âDemocracy.â
Chan ran a hand through his hair, muttering something under his breath. Then he looked at you again, his expression more serious.
âWhat exactly are you planning to say to him?â he asked.
You blinked. âI donât know. âHiâ?â
âLiar,â Seungmin said. âYou definitely practiced.â
You looked away. âMaybe a little.â
Felix nudged you. âTell us. Come on.â
You took a breath, feeling your heart flutter. âI just⊠want to tell him I admire him. That heâs a great leader, that he works hard, that his music helped me. And maybeâŠâ
âMaybe what?â Chan asked cautiously.
You gave him a wicked little smile, just to poke at him. âMaybe Iâll also tell him that I always thought his arms look even stronger up close and that heâs really, really hot.â
Chanâs soul visibly left his body.
âNO YOU WONâT,â he shouted.
Hyunjin burst out laughing, collapsing sideways. Han rolled on the floor, clutching his stomach.
âOh my god,â Han wheezed. âPlease do. Please. I need this for my mental health.â
Felix fell back against the couch, laughing so hard he made no sound for a moment.
Lee Know applauded slowly. âThatâs my favorite sentence youâve ever said.â
Seungmin just stared at you, impressed. âYouâre actually evil.â
I.N covered his bright red face with his hands. âI canât listen to this.â
Chan grabbed your shoulders, eyes wide. âYou are not saying that to him.â
You pushed his hands off gently. âRelax. I was kidding.â
You werenât sure if you were completely joking, but he didnât need to know that.
He stared at you for a long moment, then sighed, his shoulders dropping. âI hate all of this.â
You softened, your irritation fading a little as you looked at him. âI know you do. But you canât protect me from⊠everything, Chan. And you definitely canât protect me from having a crush.â
He looked down. âI know. I justâŠâ
âYou still see me as the kid who used to follow you around the house and cry when you left for practice,â you said gently.
He smiled sadly. âYou remember that?â
âWell duh,â you said. âBut Iâm not that kid anymore.â
He looked at you like he was trying to see both versions of you at once. Then he nodded, slow and reluctant.
âOkay,â he said finally. âFine. You can go to your⊠send-off. On one condition.â
You raised an eyebrow. âWhich is?â
He pointed a finger at you. âYou tell him exactly who your brother is. And that Iâm watching.â
You laughed. âWhat, like, âHi, Iâm Y/N, my brother is Bang Chan and heâs very scaryâ?â
âExactly,â Chan said.
Hyunjin snorted. âYou are not scary.â
âHey!â Chan protested.
Felix leaned his head on your shoulder with a grin. âCan you imagine if S.Coups looks at her and goes, âOh, Chanâs sister? Iâve heard about you.ââ
Chan paled. âWhy would you say that?â
Han wiggled his eyebrows. âMaybe sheâs his type.â
âHan,â Chan warned.
You grinned, feeling lighter now that everything was out in the open. âDonât worry. Iâll behave.â
He looked unconvinced, but he gave a tiny nod. âJust⊠be careful, okay?â
âI will,â you said.
âAnd no more reading thoseâŠâ He waved a hand at your pocket. âThose things in the dorm. At least not when Iâm around.â
You smirked. âNo promises.â
âY/N,â he groaned.
You bumped your shoulder into his. âFine. Iâll read them in my room.â
âThatâs only slightly better,â he muttered.
The tension in the room faded, replaced by warm laughter and teasing. Han and Hyunjin already started imagining what you would say at the send-off. Seungmin threatened to secretly record your reaction. Felix promised to help you choose an outfit that made you feel confident but ânot too deadly,â as Chan put it.
As the chaos settled, you sat back on the couch again. âPretty Womanâ still played softly on repeat, Mingyuâs and S.Coupsâ voices blending into the background.
You opened Tumblr again out of habit, then paused. Slowly, you turned your phone so only you could see the screen.
Lee Know dropped down beside you, leaning in just enough to annoy you. âSo⊠was it at least a well-written fanfic?â
You thought about it, then nodded. âYeah. It was.â
He hummed. âYou know, if Chan annoys you too much, you could always write your own version.â
You smirked. âMaybe I will.â
Across the room, Chan looked over, suspicious. âWhat are you two plotting now?â
âNothing!â you and Lee Know said in unison.
You smiled to yourself as you scrolled to your favorite part again, heart light. They still treated you like a kid sometimes, and you still wanted to scream about it sometimes. But they listened. They backed down. They let you be you, even if they grumbled about it.
