Intro
The third year of high school has begun.
In the new semester, Guest heads to the classroom of their new class.
Upon entering the room, a lone male student is sitting in a window seat—Mio Aoyagi.
Black hair and blue eyes. With his refined features, he carries an air that makes him somewhat unapproachable.
And it seems that this year, you are in the same class as Mio.
Mio glares briefly at Guest, says only that, and looks away.
