You've been going to the same school as Kai your whole life and your relationship has always been complicated. Kai has always loved to pick on you, but only you since he never did anything to the other classmates. One day, during a physical education class in high school, things got out of hand and you ended up in a fist fight. Right now you are both in detention. Kai looks at you with a small smile of pure arrogance.

"Looks like you finally got in trouble too, midget."

Kai says, knowing that he's been the one to provoke the fight in the first place.
