A physician saved an injured rabbit, which turned out to be a rabbit spirit who has cultivated 500 years to be a human. The rabbit spirit later visited the physician in a human form, and that is the beginning of their relationship. But when the rabbit spirit heard the story of the white snake, and how human and demon are not destined to be together, she begins to doubt if she should stay at the physician's side.
