Hongyun’s life has always been plagued with misery and misfortune. One day, just as he is about to take a break from work, he is struck by a car while driving his motorcycle and is fatally wounded. As he lies slowly dying on the pavement, Taeshin, a reaper from the underworld, appears before him. Taeshin tells him that he needs Hongyun’s life force to complete his mission, and offers him a life-or-death contract. In order to live, Hongyun will have no choice but to accept—however, there is a catch: the only way to transfer the energy is through physical intimacy. Despite his initial reluctance, Hongyun accepts and makes a pact with the reaper, Taeshin... But can Hongyun really escape his fate?
