The silence didn't break.
It stretched.
Thin.
Fragile.
Like something that would shatter the moment either of them spoke.
Kazuha's wrist was still in his hand.
Warm.
Real.
"…Ruko?"
Her voice was soft.
Careful.
But he didn't let go.
Not yet.
"…We've known each other since we were kids."
His voice came out lower than usual.
Steady.
But not calm.
Kazuha blinked slightly, caught off guard by the sudden shift.
"…Yes."
"You know how I am."
A pause.
"How I think."
His grip tightened—just a little.
"What I don't do."
Kazuha's eyes softened.
"…I know."
Ruko exhaled slowly.
"…So don't lie to me."
The words landed heavier than he intended.
But he didn't take them back.
"I'm not asking as someone from the club."
His gaze sharpened.
"I'm asking as me."
A beat.
"As someone who trusted you longer than anyone else here."
Kazuha's breath hitched—just slightly.
"…Please."
That word—
It barely left his lips.
"…Tell me the truth."
The hallway felt colder.
Quieter.
"…Are you Mitsuru?"
"…The one I talked to back then."
"…The one I—"
He stopped himself.
A pause.
"…The one who left."
Silence.
Kazuha didn't answer immediately.
Her eyes met his.
Steady.
But there was something in them.
Something he couldn't read.
Then—
"…No."
The word came out gently.
Without hesitation.
Without stutter.
"…I'm not."
Ruko didn't move.
Didn't blink.
"…I don't know anyone named Mitsuru."
Her voice didn't waver.
"Where did you even met her?" Kazuha asked looking at Ruko
"Nervanox" He replied
"…I've never played Nervanox before during middle school"
Another pause.
"…I'm sorry."
The air shifted.
Just slightly.
Ruko held her gaze for a moment longer—
Searching.
For cracks.
For hesitation.
For anything.
But—
There was nothing.
"…I see."
His hand loosened.
Then—
He let go.
Kazuha's wrist fell back to her side.
"…Then it's not you."
His voice returned to normal.
Calm.
Almost too calm.
"…That leaves the others."
Kazuha watched him carefully.
"…Ruko…"
"…What's going on?"
A pause.
Ruko looked away.
"…It's nothing big."
"…Don't brush it off," she said softly.
"…You wouldn't ask something like that unless it mattered."
Silence.
Then—
"…She's here."
Kazuha's eyes widened slightly.
"…What?"
Ruko leaned against the railing, staring down the dim stairwell.
"…Mitsuru."
A beat.
"…She's one of you."
The words hung in the air.
Heavy.
Unavoidable.
"…That's impossible," Kazuha said.
"…It's not."
Ruko let out a quiet breath.
"…I heard her."
"…What?"
"…In the clubroom."
His grip tightened slightly against the railing.
"…She talked to me."
Kazuha's expression shifted.
Concern.
Confusion.
"…What did she say?"
Ruko hesitated.
Then—
"…She made a game."
"…A game?"
"…Yeah."
A faint, humorless smile.
"…Just like her."
He closed his eyes for a moment.
"…She said if I can figure out who she is…"
"…By the time we graduate…"
His voice lowered.
"…She'll answer everything."
Silence.
The weight of it settled between them.
"…That's…" Kazuha started, then stopped.
"…Cruel."
"…Yeah."
Ruko opened his eyes again.
"…But that's how she is."
A pause.
"…She always did things her way."
Kazuha looked at him.
Really looked at him.
"…You're going to play along."
It wasn't a question.
"…Yeah."
"…Even after what happened?"
Ruko didn't answer immediately.
Then—
"…I need to know."
His voice was quiet.
"…Why."
Silence.
Kazuha's expression softened.
"…You haven't moved on at all."
Ruko scoffed lightly.
"…Don't say it like that."
"…Then how should I say it?"
He didn't respond.
Because—
He didn't have an answer.
Kazuha took a small step forward.
"…Then I'll help you."
Ruko blinked.
"…What?"
She smiled.
Not the perfect student council smile.
Not the polite one she showed everyone else.
But something softer.
"…I'll help you find her."
A pause.
"…The girl behind the screen."
Ruko stared at her.
"…Why?"
Kazuha tilted her head slightly.
"…Because you asked me to trust you."
A beat.
"…So now, you trust me too."
Silence.
Then—
Ruko let out a small breath.
"…You really haven't changed."
Kazuha smiled faintly.
"…I'll take that as a compliment."
They stood there for a moment longer.
The quiet between them no longer heavy—
But shared.
"…Let's go," Kazuha said.
"…It's getting late."
"…Yeah."
They started walking again.
Side by side.
But this time—
There was something new between them.
Not just familiarity.
Not just history.
But a secret.
A game.
And a promise.
Unseen—
Unspoken—
But already pulling them forward.
Because somewhere—
Among the remaining three—
Was the girl who started it all.
And this time—
Ruko wasn't going to lose her.
