Baek Dohwa had been having the same dream since childhood— a dream where she shared her body with a faceless man in a world of darkness. Due to these dream-bound unions, she lost everything and was even forced to take her own life. On her way to die, she was attacked by yokai (monsters), but a young yokai saved her from the brink of death. Moved by the gesture, Dohwa brought the dying creature to her home, gave him the name Goyo, and cared for him with deep affection. However, after drinking her blood, the young yokai suddenly matured into an adult and began to lust after her. Meanwhile, Wolcheon Geum Harang—the man from her dreams who had secretly been watching over her in this life— also starts moving toward the place where Dohwa and Goyo now reside. Entangled in the karma of a past life, Dohwa is caught between two mysterious men. But what is the true reason behind their obsession with her…?
