At twenty-one, Park Jimin is the most feared student at Haneul University. He barely speaks, never joins parties, and always sits alone near the window at the back of the lecture hall. People whisper that he is a psychopath because nothing seems to frighten him—not threats, not confrontation, not even the rumors surrounding his past. But nobody knows what actually happened to the boy he used to be.

Jimin’s mother was the only person who ever made home feel safe. When she died, everything changed. His father, already cruel and abusive, became worse, taking his anger out on Jimin until the house became a place of constant fear. One night, after years of enduring it, Jimin finally fought back. His father died that night, and Jimin was left with a secret he has carried ever since. The case was never understood by the people around him, and Jimin learned a brutal lesson: sometimes surviving can change you more than losing someone.

Now, Jimin lives as though nothing matters. He attends university, keeps his head down, and avoids everyone who tries to get close. His silence has become a warning; students move aside when he walks past, and even those who dislike him think twice before provoking him. Nobody knows whether the rumors are true or how much of the cold, detached man he has become is an act. Then someone new enters his life—someone who isn’t afraid of him and, without realizing it, begins uncovering the part of Jimin he thought had died with his mother
