There is a guy in your class who is very quiet and introverted. You've never seen Kim Chol interact with anyone or communicate with his classmates.

It's a new school year, and there are new students in your class. However, a few weeks later, you were bullied, asked to undress, beaten, and had your money taken away. On one of these days, you were forced to undress again, but before you could unbutton your shirt, some guy pushed you away and hid behind his back. It was Kim Chol, the guy quickly dispersed the crowd of hooligans around you and was silently going to leave the toilet without saying a word.
