By the time they reached the classroom, the lesson had already started.
The hallway outside was quiet, a sharp contrast to the noise they had just left behind. Caelum slid the door open carefully, trying not to draw attention.
It didn't work.
A few students looked up anyway.
The teacher paused for a brief second, then simply gestured for them to enter.
"Take your seats."
Caelum nodded and walked in without saying anything. Amoriel followed right behind him.
The room felt calmer than before lunch.
Less chatter.
More focus.
He sat down and exhaled quietly, trying to settle his thoughts back into something normal.
Beside him, Amoriel sat with the same composed expression as always, her posture straight, her attention already shifting toward the lesson.
For a moment, everything felt steady.
Then Caelum noticed.
Lyra was already in her seat.
Behind him.
Her book was open, pen moving across the page as if she had been there the entire time. No hesitation. No glance in his direction.
Just quiet concentration.
Caelum turned slightly.
"You got back fast."
Lyra didn't stop writing.
"I didn't leave for long."
Her voice was even.
No edge.
No teasing.
Just simple.
"You left before we did," he said.
"Yeah."
A short pause.
"Got tired of the noise."
That made sense.
She had always been like that.
Caelum nodded once and faced forward again.
"Fair enough."
Amoriel looked back at her.
"You were not present when we returned."
Lyra's pen slowed just a little.
"I came back during the first part of the lesson," she replied. "You were busy."
Caelum didn't need to ask what she meant.
Lunch.
Amoriel nodded.
"I understand."
Lyra didn't respond.
The teacher continued explaining something at the front of the class, chalk moving steadily across the board. The rest of the students followed along, the room settling into a quiet rhythm again.
Caelum tried to focus.
He really did.
But something kept pulling at his attention.
Not in front of him.
Behind.
The absence of small things.
No quiet comments.
No random questions.
No light taps on his chair to get his attention.
Just the faint, steady sound of writing.
He shifted slightly in his seat, then stilled again.
Beside him, Amoriel leaned closer, her voice low enough not to carry.
"Caelum."
He didn't look at her.
"What."
She paused briefly.
"In the cafeteria."
He closed his eyes for a second.
"Do we have to continue that conversation now."
"I am refining my understanding."
"…Of course you are."
A small silence followed.
Then she asked,
"Was your reaction influenced by embarrassment?"
He opened one eye slightly.
"…Yes."
"I see."
She didn't continue immediately.
Instead, she seemed to think about it.
"Then the emotional response was not solely tied to affection."
"Correct."
That was the end of it.
No strange conclusions.
No loud statements.
Just a quiet exchange.
Behind him, Lyra's pen stopped for a moment.
Then resumed.
Caelum leaned back slightly, staring at the front of the room.
Something about this felt harder to deal with than Amoriel's questions.
At least those were straightforward.
This—
This was just… off.
Amoriel looked past him again, her gaze resting briefly on Lyra.
"She is quieter than before."
Caelum let out a small breath.
"She's focusing."
"That is not the only difference."
He didn't turn around.
"You're overthinking it."
Amoriel considered his answer.
Then nodded once.
"If you say so."
The lesson continued.
Time passed slowly, but not uncomfortably.
Just enough to make the small changes more noticeable.
When the teacher asked a question, Lyra answered like usual.
Clear.
Accurate.
Composed.
Nothing wrong.
And yet—
When she sat back down, she didn't say anything else.
No follow-up.
No glance forward.
Just silence again.
Caelum rested his elbow on the desk, his gaze fixed ahead.
"…Weird," he muttered under his breath.
Amoriel heard him.
"You have used that word twice."
"Because it fits."
She tilted her head slightly.
"Do you want to understand it?"
He didn't answer right away.
Then,
"…Not really."
Amoriel studied him for a moment.
Then simply nodded.
"I see."
The rest of the class passed without anything major happening.
But when the bell finally rang, the quiet didn't disappear.
It lingered.
Subtle.
Unresolved.
And somehow—
More noticeable than any noise.
