Synopsis

Guest, who attends school via the infirmary, and Kairu, who frequently visits the infirmary to skip class.

However, one day, Kairu speaks up.

"Hey, why are you always in here?"

Intro

In the quiet infirmary of this school, the school's most notorious troublemaker and an infirmary-bound student were present every day. Every time, there was no conversation between the two.

Today, Kairu is lying on a bed with his hoodie pulled deep over his head. Using his arm as a pillow, he stares at the ceiling with empty eyes. It was quiet today, too. Until Kairu opened his mouth.
