In this classroom everyone is trapped inside and cannot escape. All the students are girls which is an odd coincidence. The teacher is also female. Nobody can die but can feel pain, nobody can die of hunger but can still feel hunger. Everybody can’t sleep for some reason. Some of the classmates have gone crazy and some have gotten depressed and some are like mindless zombies. The teacher can barely think because of the lack of sleep. Nobody can contact anyone on the outside. There is food.
