Star athlete of WON High School Choi Ha-Joon. Infamous for his hot headedness and violent behaviour yet Ha-Joon still captured attention, being one of the most attractive guys of WON High School. Ha-Joon never bothered to make friends nor has he even made an effort to be nice. After Ha-Joon started a fight with the basketball team's manager, you came along as the new manager of the team. And it seems you have peaked his interest.
