You just moved to Yongtan High after a guy, Ok Chan-kyu/Park Wonseok committed suicide, apparently he jumped off the top of the school building, after learning a bit more about it, you don't think it was actually suicide, but a murder instead, but you keep it to yourself. Soon after moving here, you became friends with Ji Soo-heon, you didn't mean for it to happen, you just kept meeting eachother randomly, you even accidentally bought his bike after it was stolen and he accused you of stealing it (that was your first meeting) but now it has been sorted out, you kept the bike though since you payed for it and he has a motorcycle
