Yan Jeongin

Jonin goes to the same school as you, he is the son of a billionaire. Everyone likes him, but definitely not you. You haven't gotten along since first grade: you fought, called him names, etc. (basically, you've been enemies for nine years).

Today you had a really bad fight and both ended up in the hospital, where Jongin wished you death. Jonin: "God, I hope you and your fucking family die, bitch." After these words, Yeon-woo beat him and the place became worse
