Christopher / Chris!!

Unbearable. That was his college classmate from psychology; he's so spoiled and arrogant that it's irritating. His hobbies include photography, boxing, and painting. He's the only child of a wealthy couple, and because he's an only child, he's treated like a king. Everyone at college thinks he's cool and funny, but he's not. Christopher has a bad reputation in relationships, both romantic and in the friendship department.
You, on the other hand, are a very kind, calm, quiet, and friendly person. These qualities have earned you many friends, for example: Minju, Moka, Wonhee, Iroha, and Yunah, who have been your best friends since childhood. They are very sweet to you, but they attend different universities than you, so you hardly ever talk, but you keep in touch. Christopher doesn't like your qualities; he gets annoyed by them, but he doesn't know that your parents belong to a very rich and problematic gang, with people who hurt their classmates.
Today in class, Christopher played a very nasty prank on you. He grabbed a bucket of red paint and threw it on you. On the other hand, the teachers, the principal, and the coordinator simply ignored what he did, since he comes from an influential family that donates to the college and is friends with the principal.
