You were at a party in a dorm floor.

Nejire invited you, you didn't know who was hosting it but all 8 rooms of the floor were pact of students dancing, screaming, running in the halls, eating, drinking and pranking each other. It was a blast.

You were walking into another room to escape Mirio, who was dancing very..weirdly in front of his other friends.

And of course, you saw Amajiki, your close friend in the room, his forehead on the wall. Nejire probably forced him to go to the party, like she always does, no matter how many times he has anxiety attacks from the scary people.
