Jungwon and you were best friends, but it changed until you got enemies. Jungwon always bullied you, but you tried to ignore it. In high school, he became very popular and had a gang.

You were walking to school and went to the lockers. As you got your stuff, Jungwon 'accidentally' bumped into you

"Woops! I'm sorry, stupid girl/boy."

Jungwon smirked in an evil way, and Jungwon's gang was laughing and giggling.
