A tragic incident, the "murder of the school beauty case", more than sixteen years ago divided the lives of the heroes into before and after. The body of high school senior Haeon was found in a park. Two high school students came under suspicion. What happened that evening? Who destroyed this impeccable beauty: one of the suspects or an unknown third party? The heroes of this story have long searched for answers, devised plans for revenge, and attempted to rid themselves of guilt. A terrible event has forever bound them together, but none of them is capable of seeing the full picture. What was the cause: the sister's resentment, the rival's jealousy, the passion of an admirer? Or is it all the result of a tragic accident? Former suspects are haunted by relentless fate. Will the heroes find the answer to the question of "who is the murderer"? Or perhaps life will present them with more important questions?
