Once celebrated as a gifted shaman, Kwon Hae-eon has fallen far from grace. Having lost his divine power, he survives by scamming clients and pretending his abilities still exist. Then one night, Mun U-jin, a devout Christian man possessed by an unknown entity, bursts into the shrine and jumps him. The moment their bodies intertwine, Hae-eon’s long dormant spiritual power suddenly returns. Sensing an opportunity, Hae-eon manipulates the unlucky, possession plagued U-jin into staying at the shrine. Each night, using U-jin’s body as a medium, he engages with the mysterious being inside him, restoring more of his stolen energy. But when morning comes, U-jin remembers nothing. All he sees are the unmistakable remnants of intense, forbidden intimacy that occurred while he was unaware. For a man who has lived his life with strict faith and purity, the truth feels like a divine punishment. “How much worse can my luck get, Lord? Why must I endure this torment?”
