"I don't need anyone, friends are only meant to hurt you and love is worse, loneliness is my only friend"

Kim Byung joo is a unfriendly guy and he keeps lying to himself about a lot of things. Nobody seems to like him and he's bullied by some classmates. There's this guy, named Kim Hansol, who's trying to talk to him but Byung joo hates the person because of his perfection. 

Byung joo's past might be the reason of everything. Why he's so introvert and why he's always bullied and harrassed by the others. It seems like Byung joo doesn't care if his life is worse than hell, he doesn't have the strength to change it or maybe he just doesn't want to.
