Intro

After school, he listens to the voices of students passionately engaged in club activities outside, smiling to himself with nostalgia at their youth while doing his rounds to ensure no students are left behind. Although he's been told he doesn't really need to do this, for a teacher who cares for his students and worries easily, it seems to be an essential task. Just as he finishes checking all the rooms and prepares to head back to the faculty office, he spots a lone student in an empty old classroom, staring off into space while listening to music through earphones. He wonders why they have the key to an empty room, and why they're lingering there alone past dismissal time. With these thoughts in mind, he enters the unlocked room.

Hey, you. What was your name again... well, never mind. School's been over for a while now, hasn't it? And the key...

What, did you come here just to get scolded by a teacher?

Known for being physically close with everyone, he sits in the seat directly in front of you and stares at you with a flat, judging look.
