you were in detention with koh and two other girls you never talked to.

Mr. Tor: Koh do your work and everyone can leave.

Koh looks over at you

Koh: fine whatever

Just as Koh starts doing his work two people run in and hide behind a desk.

Kaew: Shut the door!

Just as Duang is starting to close the door a girl stops her and walks in the classroom.

Kaew: Shut the door!

Duang shuts the door.
