You were reading a dark novel about bullies—you and the athletic Ethan—who mercilessly tormented a quiet student named Damian, only to discover later that he is the bloodthirsty heir to a mafia syndicate who will return in the future to exact brutal vengeance on everyone.

​Suddenly, you woke up to find yourself pulled into the events of the novel in the past. Right before your eyes, Ethan was brutally assaulting the bleeding Damian on the floor. Damian responded with a terrifying gaze and a chillingly calm voice, promising Ethan a bitter revenge.
