There was something different about the way mornings felt, though it wasn't something that could be easily explained or even clearly noticed unless someone paid attention to the smallest changes, the kind that slipped past without leaving any obvious trace, and for Akira, who rarely gave much thought to things that didn't directly involve him, it should have been just another ordinary day, no different from the ones that came before it.
And yet, when he reached the classroom door, his steps slowed—just slightly.
Not enough to call it hesitation.
Not enough to question.
Just enough to exist.
The door slid open, revealing a classroom that hadn't fully awakened yet, a few students scattered across their seats, quiet conversations blending into the background without ever becoming clear, and the faint light from the windows stretching across the desks in long, soft lines.
His gaze moved across the room—unhurried, indifferent—until it reached the back.
And then it stopped.
Rin was already there.
She wasn't looking at the window this time.
She wasn't pretending to be distracted.
She was looking at him.
Directly.
For a moment, neither of them moved.
It wasn't long, not even enough to be called a pause, but it lingered just enough to feel different from before, as if something had quietly shifted into place without either of them realizing when it had happened.
Rin reacted first.
She turned her head away quickly, a fraction too fast to be natural, her expression tightening for a brief second before settling back into something more familiar.
"…You're late," she said.
The words came out automatically, carrying a tone she had already used before, though this time it felt less certain, like something she said because she didn't know what else to say.
Akira stepped inside, closing the door behind him.
"I'm not."
"…You always say that."
"Because it's always true."
Rin clicked her tongue softly, her fingers tapping once against the desk before stopping.
"…That's not the point."
Akira paused beside his desk, his attention shifting toward her just enough to acknowledge the conversation.
"Then what is?"
For a moment, Rin didn't answer.
Her gaze lowered, then shifted away, as if the question itself had caught her off guard.
"…Nothing," she muttered.
The word felt incomplete even as she said it.
He didn't ask again.
He sat down.
And just like that, the moment passed—
though not completely.
The class began soon after, the teacher's voice settling over the room, steady and familiar, chalk moving across the board in quiet, repetitive strokes, and the scattered noise fading into something more controlled, more distant.
It should have felt the same as always.
But it didn't.
Not entirely.
Rin tried to focus on her notebook, her pen moving just enough to give the impression that she was following along, though every now and then, her attention slipped, not fully, not obviously, just brief shifts that pulled her gaze slightly to the side before she forced it back again.
It was subtle.
Almost unnoticeable.
But it was there.
Akira didn't react to it.
At least, not in any visible way.
But once or twice, his eyes paused just a fraction longer than usual, as if something had registered without forming into a clear thought.
When the teacher wrote a problem on the board, explaining it step by step, a few students immediately looked lost, though none of them spoke up.
Rin stared at her notebook.
Then at the board.
Then back again.
Her pen hovered above the page.
Unmoving.
"…This doesn't make sense," she muttered quietly, the words slipping out before she could stop them.
"Which part?"
The voice came from beside her—calm, simple, without hesitation.
Rin stiffened slightly.
"…I wasn't asking you," she said quickly, her tone sharper than necessary.
Akira didn't react to that.
"You said it out loud."
"…That doesn't mean I was talking to you."
"Then who were you talking to?"
She frowned, her grip tightening slightly around her pen.
"…No one."
"Then it's fine."
"…What's fine?"
"Answering."
Rin turned toward him, her expression caught between irritation and something less defined.
"…You're annoying."
"You said that before."
"…I'm saying it again."
The exchange ended there.
But the space between them didn't return to silence the way it had before.
It lingered.
Rin hesitated.
Just for a moment.
"…It's this part," she said finally, pointing at her notebook, though her finger didn't stay still, as if even that small action felt like something she might take back.
Akira leaned slightly closer—not enough to invade her space, just enough to see clearly—and his gaze moved across the page.
"You skipped a step," he said.
"…I didn't skip it."
"You did."
"…I just didn't write it."
"That's the same thing."
"…It's not."
For a brief second, neither of them spoke.
Then, without arguing further, Akira reached over and rewrote the missing step, his movements simple, precise, as if the action itself didn't require explanation.
"Now it works."
Rin looked at it.
Then at her own attempt.
Her expression didn't change much.
But something in it shifted.
"…I would've figured that out," she said.
"Probably."
"…Then why did you do it?"
"You said it didn't make sense."
Rin looked away.
"…That doesn't mean I needed help."
"Okay."
The answer came too easily.
Rin paused.
"…You're not even going to argue?"
"You said you didn't need help."
"…You're really weird."
"That's fine."
She stared at him for a moment, as if expecting something more—some kind of reaction, disagreement, anything—but nothing came.
"…It's not supposed to be fine," she muttered, quieter this time.
The conversation faded again.
But it didn't feel like before.
Not distant.
Not awkward.
Just… unfinished.
When the bell rang, the room filled with movement once more, chairs shifting, voices returning, the structured quiet dissolving into something more familiar, and as Akira stood up and reached for his bag, Rin hesitated.
Not because she didn't know what to say—
but because she didn't want to think about why she wanted to say anything at all.
"…Hey," she called out.
He stopped.
Turned slightly.
"What?"
Rin avoided his gaze.
"…You're coming tomorrow too, right?"
The question came out naturally.
Too naturally.
Akira tilted his head slightly.
"I always do."
"…I know that," she said quickly.
"…I was just asking."
"Then yeah."
A pause.
"…Good."
She looked away immediately after.
"Not that it matters."
"Right."
And then he left.
Rin remained seated, her fingers lightly tapping against the desk, her gaze drifting toward the empty space beside her.
"…It's just a seat," she muttered quietly.
But even after saying that—
she didn't move.
The next day,
she would still be there first.
Rin stared at him for a few seconds longer than necessary, her expression caught somewhere between irritation and something she refused to understand.
"…You're actually unbelievable."
"I get that sometimes," Akira replied calmly.
That only made it worse.
She looked away, crossing her arms.
"…Just don't talk to me tomorrow."
"Okay."
A pause.
"…But sit here."
