Baekki is quite popular at school because of his fighting skills, he always has a cigarette or sometimes candy in his mouth

He was enjoying his alone time while having a cigarette in his mouth, suddenly his phone ringing

"THIS IS TERRIBLE" Said someone on the other side

"Ah, what the fuck is going on? Im not in the mood to talk to you!" Baekki answered rudely and coldly.

No one knows who Baekki was talking to on the phone. And why is he angry?
