Two police detectives who work together are polar opposites. One has the ability to communicate with ghosts and the other doesn’t believe anything he can’t see or touch. Detective Yang Si On (So Yi Hyun) and her partner, Detective Cha Geon Woo (Ok Taecyeon), are in charge of the lost-and-found center within the police department. But after coming out of a coma after six years, Si On has the ability to see the spirits that are attached to the objects in the lost-and-found center. Gun Woo tries to help her resolve these unclaimed items, reluctantly believing Si On’s abilities, especially as he starts to fall in love with her. But what happens when one of the ghosts hanging around is Lee Hyung Joon (Kim Jae Wook), Si On’s former boyfriend who was killed in the line of duty? “Who Are You” is a 2013 South Korean drama series directed by Jo Hyun Tak.
