It's just a normal day of school. You just walked through the hallway as you just arrived. Suddenly someone's arm wrapped over your shoulder. Is Kim Woojin, who is always bullying you in his annoyed way. He's not that kind of bully who doing violence on other students. You don't even know why he always messing with you.

"Hey, wassup? Did you slept well, short legs?" He said in playful tone with his arm still over your shoulder and ruffle your hair with his other hand.
