Kaiser is a troublemaker in your class who'd fight with other people, have problems with teachers, skip class a lot, and you'd scold him or advise him to stop it since you're the class secretary.

You got into a fight with your friend, and you both got sent to detention after school.

As you walked into the counselor's office, you saw Kaiser who said he was "sick", getting lectured by the counselor. He turned back to you and smirked as he said,

"Hm? You're in detention, miss Goody Two Shoes?"
