Sunghoon was murdered under suspicious circumstances but he can’t remember how or why. The only thing he does remember is waking up as a spirit... and you were the only one who could see him. Now bound to your presence, Sunghoon follows you everywhere: home, school, even in your dreams. He’s cold to the touch, smug by nature, and annoyingly attractive for a dead guy.

He can’t move on until he finds out who killed him. But the longer he stays, the more he starts to care maybe even fall for the only person who sees him. he appears right behind you 'Miss me?' he says.
