The hardest part wasn't pretending you weren't in love with Seonghyeon.
It was pretending you weren't allowed to show it.
Every schedule became an exercise in restraint. Cameras followed Cortis from the moment you stepped out of the dorm until the staff finally called it a night. Fans analyzed every glance, every smile, every accidental touch frame by frame. As the youngest memberâand the only girlâyou were already under a microscope. One wrong move, one lingering look, and rumors would spread before you even got back into the van.
So the two of you became experts at acting.
He ruffled your hair on variety shows because that's what an older member would do.You shoved his shoulder when he teased you because that's what the maknae would do.
Everyone laughed.
No one realized the only reason you pushed him away was because you desperately wanted to do the opposite.
"Can someone help her with her microphone?" The stylist's voice echoed through the dressing room. Before anyone else could react, Seonghyeon's head lifted instinctively.
"I'llâ"
He stopped himself.
The silence only lasted a second, but you noticed it.
One of the other members stood instead.
"I got it."
Seonghyeon leaned back against the wall, jaw tightening ever so slightly.
Your eyes met across the room.
His expression remained perfectly neutral.
Only you noticed the apology hidden there.
I forgot.
You smiled almost imperceptibly.
It's okay.
Halfway through rehearsal, the choreographer announced another run-through.
Everyone groaned.
You dropped onto the practice room floor beside the mirror, exhausted, reaching for your water bottle. Before your fingers could close around it, another bottle slid silently toward you.
You looked up.
Seonghyeon was already walking away.
He hadn't looked at you.
He hadn't said your name.
To everyone else, it could have been meant for anyone.
Still...
The bottle cap had already been loosened.
Just the way he always did for you.
That tiny gesture lingered in your mind for the rest of practice.
It shouldn't have mattered.
It was just a water bottle.
But hidden relationships weren't built on grand declarations.
They survived because of moments like that.
The extra hoodie left outside your bedroom door when he knew you'd be cold.
The way he quietly switched meals with you whenever the catering forgot you couldn't eat something spicy before performances. The barely noticeable tap against your wrist whenever he walked pastâa secret way of saying I'm here.
Nobody noticed.
Nobody except you.
The tension only got worse during live broadcasts. Fans constantly asked if any of the members had ideal types.
Dating.
Marriage.
Relationships.
You hated those questions.
The host laughed.
"So, Seonghyeon! What kind of person catches your attention?" The room erupted with teasing. You focused very hard on fixing the sleeve of your jacket.
"Someone..." he began carefully, "who works hard even when nobody notices."
Your heartbeat slowed.
"...Someone who always takes care of other people before themselves."
The members nodded thoughtfully.
"Aww."
"That's sweet."
You kept your eyes down.
Because you knew.
He wasn't describing some imaginary future girlfriend.
He was describing you.
After the broadcast ended, everyone climbed into the elevator together.
It was cramped.
Too many managers.
Too many staff.
Too many people.
By complete accidentâor maybe terrible luckâyou ended up standing directly in front of Seonghyeon.
Your backs nearly touched.
You could feel his warmth without either of you moving.
Someone shoved into the elevator at the last second.
The sudden movement threw you backward. A hand caught your waist before you lost your balance.
Firm.
Steady.
Gone just as quickly.
Nobody reacted.
The doors opened.
Everyone walked out. But your pulse never recovered.
That night, your phone buzzed while you were lying in bed.
Hyun â¤ď¸
Rooftop?
You stared at the message for almost a full minute. The company had recently reminded everyone not to wander around the dorm after midnight.
Managers had been making random checks.
Meeting him was risky.
You typed anyway.
Five minutes.
The rooftop was quiet except for the distant sounds of traffic below. He was already waiting, hoodie pulled over his head against the cool breeze.
"You came."
"I always do."
His smile was small.
Almost relieved.
For a few seconds, neither of you moved.
That was becoming your habit lately.
Standing close enough to touch.
Never actually doing it.
Because after spending entire days pretending strangers meant more to each other than lovers did...
Even privacy felt unfamiliar.
"I hated today," he admitted quietly. You looked at him.
"Because of rehearsal?"
He shook his head.
"I wanted to help with your mic."
You smiled sadly.
"I know."
"I almost did."
"I know."
"I had to watch someone else fix it instead."
His laugh was hollow.
"It's ridiculous."
"It isn't."
"It is."
He rubbed the back of his neck, looking out over the city lights.
"I keep forgetting that I can't just..." He gestured helplessly toward you.
"...take care of you."
The confession settled between you.
Heavy.
Honest.
You took one careful step closer.
Then another.
Until barely a foot separated you.
"You do take care of me."
His eyes met yours.
"You leave snacks in my bag."
"You notice when I skip meals."
"You stay awake until I text that I'm back safely."
A tiny smile tugged at his lips.
"You noticed."
"I notice everything you do."
The words escaped before you could stop them.
Silence followed.
The kind that made your heart race.
"So do I," he whispered.
One more step.
That was all it would take.
You watched his eyes flicker briefly to your lips before returning to your gaze.
He swallowed.
You did too.
Neither of you moved.
Not because you didn't want to.
Because you wanted to too much.
"Princess..." The nickname was barely audible.
Just hearing it after an entire day of formal names and careful distance made your chest ache.
"Hm?"
"I've been wanting to hold your hand since breakfast."
You laughed softly, though your eyes stung unexpectedly.
"That's all?"
"No."
His voice was quiet.
"I've wanted to kiss you since you smiled at me during rehearsal."
Your breath caught.
"You looked so tired," he continued, "and all I could think about was pulling you aside for five minutes so I could remind you to take care of yourself."
"You always remind me."
"Not enough."
Without thinking, your fingers brushed against his.
It wasn't dramatic.
Just the lightest touch.
His hand immediately turned, threading your fingers together as though he'd been waiting all day for permission.
The simple contact felt almost overwhelming.
Warm.
Safe.
Real.
He let out a slow breath.
"I missed this."
"So did I."
His thumb traced lazy circles over the back of your hand, and for a moment, the world beyond the rooftop disappeared.
No cameras.
No managers.
No expectations.
Just the two of you.
Then... The rooftop door clicked.
Both of you froze.
Voices echoed from the stairwell.
Managers.
Your hands separated instantly.
You both stepped apart, hearts pounding.
The door handle turned.
For one agonizing second, neither of you breathed.
"...Huh."
A manager peeked outside, looked around the empty rooftop entrance, and frowned.
"Thought I heard someone."
Footsteps.
Then the door closed again.
The silence that followed was deafening.
You didn't realize you'd been holding your breath until Seonghyeon quietly laughed beside you.
"That was way too close."
You nodded, your heartbeat still racing.
"It was."
He looked at you for a long moment before smilingâa smile reserved only for you, hidden from every camera and every fan.
"Come on, princess."
"What?"
"If we stay out here any longer..."
He offered you the smallest, almost invisible brush of his pinky against yours as you walked toward the door.
"...I'm not going to want to keep pretending anymore."
