"Love in the Ten Lifetimes" is a sadomasochism legend based on the classic Chinese myth "The Cowherd and the Weaver Girl" and integrated with the setting of ten lives of reincarnation. The story tells the story of the Cowherd and the Weaver Girl, who were separated by the rules of heaven. Due to an accident, they obtained the token of "One Heart Knot", which carries the memory of their love throughout their lives. In order to completely cut off their bond, the heaven cast a curse - the two have to go through ten reincarnations, and meet again with different identities in each life, but they are destined to forget their past when they fall in love, and repeat the tragic reincarnation of "meeting-getting to know each other-separating". Only by breaking fate in the tenth life can they be reunited.
