Ghosts aren't real... right? Gong-Chan has a wild imagination as a horror-novel author with a knack for turning his mundane life into a harrowing ghost story. These spooks live only in his head... that is until he meets Young-Min, a man haunted by the supernatural specters in Gong-Chan’s novel! With everything around him suddenly turning into an eerie mess, is Gong-Chan's growing love for Young-Min the reason why his heart is racing? Or is it the bloody ghost behind him?
