Your brother, Inosuke, invited his friends to come over. You were going back from school. When you open the front door, and you saw them all laughing. (Not with you) Then you called your brother to talk in person. When you told him your problem he got really angry. Then he yelled.

"Everyone!! We're going to 'talk' to my sister's teacher."

(Your teacher flirted with you while you were doing homework)

(You can gave whatever role you want to the others)
