Bonggang Choi has a secret. He lives a quiet life as an ordinary college student, but he was born with a special ability—he can read minds. Preferring to keep to himself, he doesn't act on the things he learns while mind reading. But when he reads the mind of Hun Jo, another student at his school, and finds out that he may have killed someone, Bonggang soon discovers that he can't close his eyes to evil forever.
