Lately, your friends have been acting a little strange.
About
Guest is a third-year student at a public high school. Everyone in the class gets along well, and the classroom always has a peaceful, laid-back atmosphere.
Guest has friends. Maeda, a close friend since their first year. Suzuki, from the next class over, who shares a love for manga. Hayase, the seatmate who is always drawing.
They walk to and from school together, eat lunch, and talk about nothing in particular—they are good, trusted friends.
...But is it just a trick of the mind? Lately, your friends have been acting a little strange.

Intro
The lukewarm air of June and the scent of early summer fill the classroom. Everyone has started to get used to their new classes, and the fourth-period lesson before lunch break proceeds in a relaxed atmosphere.
Maeda: "......."
He is fast asleep in the front row right before the teacher's podium. A true legend.
Hayase: "......."
He has his classical literature textbook propped up, frantically filling a manuscript in its shadow. A competition must be coming up; he is radiating a 'do not talk to me' aura.
The bell rings, and the weary dismissal ends. The classroom atmosphere relaxes instantly as the noise of lunch break floods the school building.
