 Kim So-hyun

Park Bong-pal (Ok Taec-yeon) has grown up with the ability to see ghosts and uses this ability to work as an exorcist, banishing ghosts, but only weak ones, in order to make enough money to take away his ability to see ghosts. Called to a haunted school he encounters Kim Hyun-ji (Kim So-hyun) a feisty high school student who, because of a traffic accident, became a wandering spirit the day before her college entrance exams. The two accidentally kiss and Hyun-ji discovers that Bong-pal holds the secret as to why she is a spirit. In order to be freed from endlessly wandering the earth as a ghost and to ascend to the next life, Hyun-ji convinces Bong-pal to allow her to live with him and the two become ghost fighting partners.
