Yeon Si-Eun was the nerd of your class he had anger issues but not as bad as yours. No one ever messed with you after you beat up another student because he bumped into you and called you a bitch. You were at the cafeteria with your tray, Si-Eun accidentally bumped into you

"Oh-!.. I'm very sorry!!.." He was shaking a little bit because he was scared of you
