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.
“Pretty woman~” Mingyu’s voice flowed out, followed by S.Coups’ 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 in—
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.
“Why do you look like you’re studying for an exam?” he asked suddenly.
You flinched. “I’m not.”
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. “What are you doing, Y/N?”
“Nothing,” you said quickly.
That was the wrong word. The deadly word.
Han’s eyes narrowed. “Oho. ‘Nothing’ is what people say when they’re definitely doing something.”
Hyunjin, sprawled on the rug, rolled onto his stomach, chin in his hands. “Are you texting someone?”
I.N gasped. “Is it a boyfriend?”
Your nose wrinkled. “No!”
“Girlfriend?” Felix added, grinning.
“No!” you repeated, louder this time. “It’s just… some stuff.”
Lee Know stood up, wiping his fingers on his sweatpants. “Stuff like what? You’ve been staring at your phone for twenty minutes without blinking. That can’t be normal.”
You forced your shoulders to stay relaxed, your fingers tightening around your phone. “I’m just reading.”
Seungmin looked over from the armchair. “Reading what?”
You stared at him, your mind scrambling for something normal. “News,” you lied. It came out too fast.
Han snorted. “Yeah, sure. You’re humming to ‘Pretty Woman’ while reading the news? What, is Mingyu the weather forecast?”
You bit your lip. On the screen, you saw the line:
“Coups’ fingers trailed along your arm…”
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. “Show me.”
“No.” You hugged your phone to your chest.
The room got louder in an instant.
“What do you mean, ‘no’?” Chan asked, his leader voice waking up.
“What the fuck? It's my phone,” you shot back.
Felix scooted closer on the other side of the couch. “Are you watching something weird?”
You could feel your soul leave your body. “Why would you say it like that?”
Hyunjin pointed dramatically. “Everyone, she’s suspicious. Confiscate the device.”
“God...this isn't school,” 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. “Don’t touch my phone!”
Felix laughed. “Now we have to see.”
You backed away, holding your phone behind you. “It’s private and none of your business!”
“Then you should’ve stayed expressionless,” Seungmin said, standing too. “You look like someone who just read something they shouldn’t have.”
You hated how accurate that was.
Lee Know reached you first, hand out. “Come on, just show me. I’ll tell them if it’s bad.”
“Oh, that’s worse,” you said. “Absolutely not.”
You stepped away from him, almost tripping over Hyunjin, who tried to grab your wrist from below.
“Traitors, all of you!” you yelled, dancing out of reach.
“Y/N, stop running,” Chan said, standing up slowly. His voice was calm, but you heard the older-brother tone in it. “You’re going to fall.”
“I’d rather fall than show you my phone.”
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 “S.Coups x Reader – Rated T” on your screen.
“Is it at least legal?” I.N asked as he tried to move around to cut you off.
“Oh my god, yes, it’s legal!” you snapped. “I’m not a criminal, I’m just—”
You cut yourself off before you confessed anything.
Lee Know stopped and tilted his head. “You’re just… what?”
“Nothing!” you yelled again.
Chan sighed and rubbed his face. “Y/N.”
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, Chan’s arm came around from behind you. He hooked his hand over your wrist and gently but firmly pulled your phone out of your grasp.
“No!” you shrieked. “No no no no—”
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.
“Pretty Woman – S.Coups x Reader (College AU)”
Chan stared for one second.
Then another.
Then his whole expression changed.
“Oh my—” He cut himself off, his eyes widening as he scrolled a little by accident. “Okay, what the- No. No, no, no—”
“Give it back!” you lunged, but Lee Know held your shoulders, half laughing, half curious.
“What is it?” Han demanded, bouncing on his toes.
Chan looked horrified. “It’s… it’s… it’s a fanfiction.”
Hyunjin gasped dramatically. “Oh? That’s not so bad.”
Chan shook his head. “It’s a fanfiction about her and S.Coups.”
The room exploded.
“WHAT?”
“HUH?”
“EXCUSE ME?”
“SEVENTEEN S.Coups?!” Felix’s eyes almost popped out.
You buried your face in your hands and groaned loudly. “Why would you say it out loud?”
Seungmin let out a disbelieving laugh. “You’re reading S.Coups x Reader fanfic in our dorm?”
“While listening to his song,” Lee Know added. “That’s dedication tho”
I.N blinked rapidly. “Wait, so you and S.Coups… like… in the story… are… like…”
“Stop talking,” you begged. “Please.”
Chan held your phone out like it was contaminated. “It’s— it’s so weird. Why would you read this? Why would you imagine—?” He broke off, visibly disgusted. “Ugh.”
You snatched the phone from his hand before he dropped it. “Because I’m a normal human being with a crush,” you snapped.
The room went quiet.
You hadn’t 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. “So you… like him?”
You rolled your eyes. “Well, I’m not reading fanfiction about him because I hate him.”
“But he’s older,” I.N said, frowning. “And he’s, like… S.Coups.”
“And you’re pretty young,” Chan added, a stubborn edge in his voice.
You stared at him. “I’m twenty-one, Chan.”
“Exactly,” he said. “Too young.”
You laughed once, disbelief spilling out. “Wow. Okay. So when you were twenty-one, you were traveling, training, dealing with everything, but I’m too young to have a crush on an idol?”
“That’s different,” he said quickly.
“How?” you demanded.
“Because you’re you,” he said.
You threw your free hand up. “Are you fucking kidding me!”
Han looked between you two like he was watching a ping-pong match. “Okay, wait, wait. Let’s… let’s breathe. Y/N, you have a crush on S.Coups?”
You crossed your arms. “Yes. He’s hot. And amazing. And frankly, you guys could be a little less bitchy about it.”
Hyunjin choked on his drink. “You just called him hot in front of your brother.”
Chan clapped his hands over his ears. “I didn’t hear that. I refuse.”
Lee Know smirked. “I heard it clearly.”
Felix giggled. “Same.”
Seungmin leaned back in the armchair. “So that’s why you always watch Seventeen clips when you think no one’s looking.”
You glared at him. “I never said I was subtle.”
“Okay, but…” I.N looked worried. “Are you sure? Like… idol crushes are dangerous. They make you weird.”
“Too late for that, I am already weird,” you said flatly.
“That’s true,” Lee Know agreed.
You ignored him.
Chan stepped closer, his brows furrowed. “I just… I don’t like it.”
Your jaw clenched. “Huh?”
He hesitated, looking for the right words. “He’s a grown man. An idol. You’re my little sister.”
You exhaled sharply. “There it is. Little.”
“You are my little sister,” he insisted.
“I’m an adult,” you shot back. “You know that, right? Like, legally. Emotionally. Mentally. Okay, maybe not mentally all the time, but still.” You gestured at him with your phone. “You can’t freeze me at age twelve forever just because it makes you feel better.”
Felix’s smile faded slightly as he watched you. The others exchanged glances.
Chan opened his mouth, closed it, then opened it again. “I’m not trying to freeze you,” he said more quietly. “I just… don’t like the idea of some guy—”
“He doesn’t even know I exist,” you interrupted. “It’s 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?”
Han raised his hand. “Plot twist: he does.”
Hyunjin elbowed him. “Not helping.”
You ran a hand through your hair. “I get that you want to protect me. All of you do. But it’s annoying when you act like I’m a baby who can’t handle a crush. I’m twenty-one. I can find people attractive without spontaneously combusting.”
“You say that,” Seungmin muttered, “but look at your face. You’re literally combusting right now.”
You pointed at him. “That’s embarrassment. It’s different.”
Chan looked at you, his expression softening just a little. “We just… don’t want you to get hurt.”
“How am I getting hurt from reading fanfic?” you asked. “It’s not like I’m dating him. I just like him. He’s talented, he’s kind, he has that leader vibe—” you paused, side-eyeing Chan. “Which you should respect, by the way, leader-to-leader.”
Chan’s jaw tightened. “I respect him as an artist.”
“But not as someone I could maybe… I don’t know… admire?” you said.
“You can admire him,” Chan said quickly. “From far away. Very far away.”
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.
“‘Far away,’ huh?” you said slowly. “About… fanmeeting-distance?”
Felix blinked. “What does that mean?”
You smiled, innocent and evil at the same time. “I mean, like… send-off distance.”
The room fell silent.
Chan’s eyes narrowed. “What did you do?”
You slipped your phone into your pocket and shrugged casually. “I might have… booked a send-off with him.”
Time stopped AGAIN.
“What?” Chan’s voice jumped an octave.
“YOU WHAT?” Han yelped.
Hyunjin sat up so fast his hair flew. “When? How? Why didn’t we know?”
“I bought a ticket like a normal fan,” you said, savoring every second of their reactions. “Used my own grown up money. I’m allowed.”
Felix covered his mouth with both hands, eyes sparkling. “You’re going to meet him?”
“Yes,” you said, holding Chan’s gaze. “Face to face.”
I.N looked both impressed and horrified. “No way.”
Lee Know shook his head slowly. “You’re brave. Or insane. Maybe both.”
Chan stared at you like you had just told him you planned to move to Mars. “You can’t go.”
You snorted. “Oh wow...Watch me.”
“Y/N,” he said, his voice low.
You met his eyes without flinching. “I already paid. It’s done.”
He looked at the others for backup.
“Guys,” he said, helpless. “Say something.”
Han drew a circle on the rug with his finger. “I mean… she’s twenty-one. Fans younger than her go to these things all the time.”
Hyunjin nodded slowly. “Yeah. And it’s not like she’s going alone at night in some shady alley. It’s a normal event. Staff, security, all that.”
Seungmin shrugged. “And it’s S.Coups, not some random creep.”
“That doesn’t make me feel better,” Chan muttered.
Felix leaned forward. “I’ll go with her,” he offered. “If our schedule lets us. Then she’s safe and you can stop freaking out.”
Your heart squeezed. “Lix…”
I.N raised his hand. “I’ll 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.”
Chan shot him a betrayed look. “Whose side are you on?”
“Y/N's obviously,” I.N said without hesitation.
Lee Know smirked. “Honestly, I kind of want to see Chan’s face when she stands in front of S.Coups. That alone is worth supporting her.”
You snorted. “Thank you, I think.”
Chan looked like the ground had opened under him. “You guys are no help.”
“You’re outvoted, hyung,” Han said cheerfully. “Democracy.”
Chan ran a hand through his hair, muttering something under his breath. Then he looked at you again, his expression more serious.
“What exactly are you planning to say to him?” he asked.
You blinked. “I don’t know. ‘Hi’?”
“Liar,” Seungmin said. “You definitely practiced.”
You looked away. “Maybe a little.”
Felix nudged you. “Tell us. Come on.”
You took a breath, feeling your heart flutter. “I just… want to tell him I admire him. That he’s a great leader, that he works hard, that his music helped me. And maybe…”
“Maybe what?” Chan asked cautiously.
You gave him a wicked little smile, just to poke at him. “Maybe I’ll also tell him that I always thought his arms look even stronger up close and that he’s really, really hot.”
Chan’s soul visibly left his body.
“NO YOU WON’T,” he shouted.
Hyunjin burst out laughing, collapsing sideways. Han rolled on the floor, clutching his stomach.
“Oh my god,” Han wheezed. “Please do. Please. I need this for my mental health.”
Felix fell back against the couch, laughing so hard he made no sound for a moment.
Lee Know applauded slowly. “That’s my favorite sentence you’ve ever said.”
Seungmin just stared at you, impressed. “You’re actually evil.”
I.N covered his bright red face with his hands. “I can’t listen to this.”
Chan grabbed your shoulders, eyes wide. “You are not saying that to him.”
You pushed his hands off gently. “Relax. I was kidding.”
You weren’t sure if you were completely joking, but he didn’t need to know that.
He stared at you for a long moment, then sighed, his shoulders dropping. “I hate all of this.”
You softened, your irritation fading a little as you looked at him. “I know you do. But you can’t protect me from… everything, Chan. And you definitely can’t protect me from having a crush.”
He looked down. “I know. I just…”
“You still see me as the kid who used to follow you around the house and cry when you left for practice,” you said gently.
He smiled sadly. “You remember that?”
“Well duh,” you said. “But I’m not that kid anymore.”
He looked at you like he was trying to see both versions of you at once. Then he nodded, slow and reluctant.
“Okay,” he said finally. “Fine. You can go to your… send-off. On one condition.”
You raised an eyebrow. “Which is?”
He pointed a finger at you. “You tell him exactly who your brother is. And that I’m watching.”
You laughed. “What, like, ‘Hi, I’m Y/N, my brother is Bang Chan and he’s very scary’?”
“Exactly,” Chan said.
Hyunjin snorted. “You are not scary.”
“Hey!” Chan protested.
Felix leaned his head on your shoulder with a grin. “Can you imagine if S.Coups looks at her and goes, ‘Oh, Chan’s sister? I’ve heard about you.’”
Chan paled. “Why would you say that?”
Han wiggled his eyebrows. “Maybe she’s his type.”
“Han,” Chan warned.
You grinned, feeling lighter now that everything was out in the open. “Don’t worry. I’ll behave.”
He looked unconvinced, but he gave a tiny nod. “Just… be careful, okay?”
“I will,” you said.
“And no more reading those…” He waved a hand at your pocket. “Those things in the dorm. At least not when I’m around.”
You smirked. “No promises.”
“Y/N,” he groaned.
You bumped your shoulder into his. “Fine. I’ll read them in my room.”
“That’s only slightly better,” 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 “not too deadly,” as Chan put it.
As the chaos settled, you sat back on the couch again. “Pretty Woman” still played softly on repeat, Mingyu’s and S.Coups’ 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. “So… was it at least a well-written fanfic?”
You thought about it, then nodded. “Yeah. It was.”
He hummed. “You know, if Chan annoys you too much, you could always write your own version.”
You smirked. “Maybe I will.”
Across the room, Chan looked over, suspicious. “What are you two plotting now?”
“Nothing!” 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.
