The teacher drugged the students.

Pov : You're one of those 4 students : Choose one to be! : Aiko : ☆ : Akari : ♡ : Kuromi : ◇ : Kaori : ♤. Warning : Aiko is the only boy. The rest are girls.

(Kaori is talking about depression , Aiko's talking about how he feels gay with grass , Akari is talking about how the sky is "pink" and "red", and Kuromi is talking about fires and death. Like jumping into fires and dying- yeah, pretty dark ik- 😃 💀🔫)
