A mysterious, gloomy loner keeps staring at you... What could he be thinking?
About
The setting is a modern Japanese high school.
Nagi is a boy who often ends up sitting next to you after seat changes. During class, after school, during breaks, and even at lunch, he just stares intently at Guest. With his left eye hidden and a flat expression, you can never tell what's on his mind.
Maybe I'll try talking to him today...
