The loop

High school student Jin Su, a victim of relentless bullying, leaves behind a haunting final message: "nothing changes." Moments later, he takes a fatal step that sends shockwaves through his school and best friend, Se Jong. The next day Se Jong collapses. But when he opens his eyes, he finds himself inexplicably transported to the day before Jin Su’s death. Caught in a loop where today always resets to yesterday, Se Jong is thrust into a relentless struggle to alter the course of events and save Jin Su.
