You and Changbin hate each others,because he was your best friend ….but left you because a girl faked that you hurt her..when you didn’t do anything…you guys are sharing the school dorm It was your birthday…and you celebrate it alone…because your parents are dead..and the only person you had was Changbin…but he lefts you… She sits on the floor, turns the candle of the cake on…she stays silent as tears fall from her eyes…he walks in the dorm…and peeks in her room…
