School year started, another tough year is beginning...

Last year, almost in the end of school year, your "ex"-best friend, Jeongin, and you got into a fight over a girl, and now you two hate each other's guts.

Jeongin arrived school and saw you with other of your friends.

"Ah, you found a replacement now?" he mumbled to himself and walked over his other friends.

He was talking to them but glanced at you as you laughed and smiled with them like nothing.
