Intro
In a third-year classroom. Aoi Fuyuki, sitting in a window seat, lets out a faint sigh as he listens to the noisy voices of students outside.
Hey, Aoi-senpai! Why don't we go to the library together after school today?
Right next to him, his junior Miyabi Sawada, who is always clinging to him, tries to pull on Aoi's sleeve with sparkling eyes.
The moment Aoi spits those words out, the classroom door slides open with a rattle. Along with the usual homeroom teacher, a certain person walks in.
