The classroom door opened—
And the noise didn't stop.
It shifted.
Voices lowered just enough to notice. A few heads turned, then a few more, like a ripple passing through the room. Some students pretended not to look—but looked anyway.
Because she walked in.
Seo-Yeon.
Not loud. Not dramatic.
Just… present.
She stepped inside with an easy confidence, like she had done this a hundred times and never once needed permission. Sunlight from the corridor followed her in for a second, catching lightly against her hair before fading as the door closed behind her.
And just like that—
The room adjusted.
A boy in the front row sat straighter.
Someone near the window stopped mid-conversation.
A pen dropped somewhere and wasn't picked up.
Geon looked up.
"…hey—"
She didn't respond.
Didn't even look at him.
She walked straight through the rows, past curious eyes and half-whispered comments, her steps steady, focused.
Destination clear.
His desk.
Geon straightened slightly.
Why does this feel like I'm about to get scolded in public?
She stopped in front of him.
Placed the keys down with a soft tap.
"Dumbass," she said casually, "you forgot these in the cafeteria."
A few nearby students glanced over.
Geon immediately lowered his voice.
"…don't call me that in public."
Seo-Yeon finally looked at him.
One quick glance.
Assessment complete.
"Then don't forget basic things in public."
"…that's not how that works."
Ignored.
Her attention shifted.
To the right.
Yoo Ara.
Sitting beside him.
For the first time—
Close.
There was a pause.
Short.
Quiet.
Not awkward.
Not tense.
Just recognition.
Seo-Yeon's expression softened slightly.
"Hi," she said.
Ara blinked, then smiled.
"Hi."
They shook hands.
Simple.
Natural.
Geon watched like something irreversible had just happened.
This feels important. I don't know why. But I don't like it.
"You're the transfer student, right?" Seo-Yeon asked.
Ara nodded.
"Yeah."
"You settled in fast."
Ara gave a small smile.
"People are nice."
Seo-Yeon glanced at Geon.
"…some of them."
Ara followed that glance.
Looked at Geon.
And smiled.
Geon straightened instantly.
"…yeah I mean obviously, we're nice, I'm nice, like generally nice—"
Seo-Yeon cut him off without even looking at him.
"Stop talking."
"…okay."
Silence.
Then—
"…you—uh—like… girls?" Geon said suddenly.
The entire row froze.
Dae-Sung slowly lowered his pen.
"…what did you just say."
Ara blinked.
Seo-Yeon turned her head slowly.
Looked at Geon.
Then—
A small smile.
Not shocked.
Not offended.
Just… entertained.
"…maybe," she said.
Geon froze.
"…WHAT."
Ara turned slightly away, covering her mouth.
Trying not to laugh.
Failing.
Seo-Yeon leaned a little closer.
"Why?" she asked calmly. "You scared?"
"…NO."
"Yes."
"No."
"Yes."
"No."
"Yes."
Geon completely shut down.
Behind them—
A chair creaked as someone leaned back just to watch.
Ara laughed.
Not softly.
Not politely.
Actually laughed.
And for some reason—
That hit harder than anything else.
Seo-Yeon leaned back, shaking her head.
"…relax."
A pause.
"I'm not."
Geon blinked.
"…oh."
"You're funny," Ara said, still smiling.
Geon froze again.
Angel.
Actual angel.
Behind him—
Dae-Sung flipped a page and calmly wrote something.
"New variable: subject displays positive response to humor."
Geon turned slowly.
"…STOP DOCUMENTING MY LIFE."
Without looking up, Dae-Sung replied—
"It is necessary for progress."
Seo-Yeon glanced at him briefly.
"…you're still doing that?"
"Yes."
"…does it work?"
Dae-Sung paused.
"…in theory."
"…fair."
No teasing.
No mocking.
Just… acceptance.
Then—
Another voice.
"You always do this?"
Geon turned.
Han Ji-Eun.
Topper of the school.
Second rank.
Dae-Sung's academic rival.
Sharp eyes.
Straight posture.
Presence that didn't try—but didn't need to.
She stood beside the desk, observing.
Not impressed.
Assessing.
Her gaze moved across them.
Ara.
Seo-Yeon.
Geon.
Dae-Sung.
"…this is your social circle?" she asked.
"…unfortunately," Dae-Sung replied.
Ji-Eun nodded once.
"Explains a lot."
"…YOU'RE BOTH INSUFFERABLE," Geon said.
Ignored.
Ji-Eun looked at Ara.
"You're the transfer student."
Ara nodded.
"Yeah."
Ji-Eun extended her hand.
"Han Ji-Eun."
Ara shook it.
"Yoo Ara."
Ji-Eun observed her briefly.
"…you're adapting quickly."
"I'm trying."
"…good."
Then—
She glanced at Dae-Sung.
"…don't fall behind."
"I won't."
"…you already are."
A beat.
Seo-Yeon smiled slightly.
"This is fun."
Ji-Eun looked at her.
"…you encourage this?"
"Of course."
A small pause.
"It's entertaining."
The bell rang.
Sharp.
Final.
Seo-Yeon checked the time.
"…I have class."
She turned to Ara.
"See you around."
Ara nodded.
"Yeah."
Then—
She looked at Geon.
A small smirk.
"Try not to embarrass yourself more."
Geon sighed.
"…no promises."
She laughed.
Then walked out.
Ji-Eun followed shortly after.
The room settled again.
But Geon didn't.
He sat there.
Still processing.
Then slowly—
He turned toward Ara.
"…so…"
A pause.
"…you don't like girls, right?"
Ara looked at him.
Then smiled.
"…not right now."
Geon blinked.
"…RIGHT NOW??"
She laughed again.
And somehow—
That was worse.
That night—
Geon lay on his bed.
Staring at the ceiling.
Replay.
Replay.
Replay.
Her smile.
Her laugh.
Her voice.
"You're funny."
He covered his face.
"…okay."
A beat.
"…tomorrow."
Silence.
"…I'll confess."
And this time—
He meant it.
