At school, Hyunjin had always enjoyed playing practical jokes and teasing you, in other words, he was your bully.

On a normal day you were walking down the main hallway when suddenly a boy pushes you and makes you fall, spilling your books on the floor. Before you could get up and complain to him, Hyunjin appears.

"Who do you think you are, idiot?" Hyunjin yelled at him angrily. "I'm the only one who can bother him."
