The next morning felt quieter than usual.
Not because anything had changed on the outside.
Everything was exactly the same.
The same street. The same corner. The same early morning stillness that lingered in the air before the day properly began.
Ji-hoon was already there.
Seo-yoon slowed slightly as she approached him, her steps more careful than usual. For a moment, she wondered if he would look at her the way he always did, like nothing had shifted.
He did.
"You're on time," he said.
"So are you."
A small pause followed.
Then they started walking.
Side by side.
Like always.
But it didn't feel like always.
Seo-yoon glanced at him once, then looked ahead again.
"Did you go home late yesterday?" she asked.
"No."
"You weren't at the usual time."
"I had something to do."
His answer came easily.
Too easily.
Seo-yoon nodded, even though it didn't quite settle the thought in her mind.
They walked a few more steps in silence.
"I finished the project," she added after a moment.
"Already?"
"We worked quickly."
Ji-hoon nodded once. "That's good."
That was all.
No questions about who did what.
No follow-up.
Just a simple acknowledgment.
Seo-yoon tightened her grip slightly on her bag strap.
"You don't want to know anything else?" she asked.
Ji-hoon glanced at her briefly. "You said it's done."
"That's not what I meant."
"Then what did you mean?"
Seo-yoon hesitated.
She wasn't sure how to answer that.
What did she mean?
That he should ask more?
That he should care more?
That he should react?
"I just thought you'd ask," she said quietly.
Ji-hoon looked ahead again. "It's your project."
The words were simple.
But they felt distant.
Seo-yoon swallowed the response that rose in her throat.
"Right."
They kept walking.
The rest of the way passed without much conversation.
At school, Min-chae noticed it immediately.
"You two are worse today," she said, dropping into the seat in front of them.
Seo-yoon sighed softly. "We're not worse."
"You are."
Ji-hoon opened his notebook. "We're fine."
Min-chae looked between them, unconvinced. "If this is 'fine,' I don't want to see 'bad.'"
Seo-yoon didn't respond.
She didn't have the energy to argue.
Classes began, but the tension didn't fade.
It stayed.
In the way Seo-yoon found herself thinking before speaking.
In the way Ji-hoon didn't look at her unless he had to.
In the way everything felt just slightly out of place.
At some point, the teacher assigned a short activity.
"Work in pairs," she said.
The words were simple.
But for a brief moment, Seo-yoon hesitated.
Before she could turn, Ji-hoon spoke.
"I'll work with Min-chae."
Seo-yoon froze.
Min-chae blinked. "What?"
Ji-hoon had already moved his chair slightly, not waiting for a response.
Seo-yoon stared at the empty space beside her.
It had always been him.
Always.
Before she could think too much about it, someone spoke.
"Do you want to pair up?"
Seo-yoon looked up.
Hyun-woo.
She nodded slowly. "Okay."
They worked together without any issues.
Hyun-woo explained things clearly, his tone easy, his presence comfortable in a different way.
Seo-yoon responded, focused on the task in front of her.
It should have felt normal.
And yet
Her attention drifted.
Not toward the front.
Not toward her work.
But slightly to the side.
Ji-hoon was talking to Min-chae.
Actually talking.
More than he had talked to her in the past two days.
Min-chae laughed at something he said.
He didn't smile much.
But he didn't look distant either.
Seo-yoon looked away quickly.
Her chest felt tight.
For no reason.
No reason at all.
When the activity ended, everyone returned to their seats.
Ji-hoon moved back beside her.
Like nothing had happened.
Like it was just another moment.
Seo-yoon didn't say anything.
Neither did he.
The rest of the day passed like that.
Quiet.
Careful.
Unfinished.
After school, Seo-yoon packed her bag slowly again.
This time, she didn't wait.
She stood up first.
"I'm leaving," she said.
Ji-hoon looked up. "Okay."
No offer to walk together.
No "wait."
Just that.
Seo-yoon nodded once and walked out.
Her steps were faster than usual.
She didn't slow down.
Didn't look back.
She told herself it didn't matter.
That this was normal.
That people didn't always have to walk together.
That nothing had changed.
But it didn't feel like nothing.
It felt like something had been quietly placed between them.
A line.
Not visible.
Not spoken.
But there.
And neither of them was crossing it.
Outside, the air felt warmer again, the sky clear and bright in a way that didn't match how she felt.
Seo-yoon walked past the gate, past the corner, past the place where he always waited.
This time, she didn't stop.
Behind her, the school grew quieter with distance.
Ahead of her, the road stretched out, unfamiliar in a way it had never been before.
Because for the first time
She was walking it alone.
And somewhere between one step and the next
She realized
She didn't know how to go back to the way things were
Even if she wanted to...
