Although Miyo Saimori is born into a family of supernatural beings, she does not have the rare "talent of seeing ghosts" like her sister. She has been despised by her father since she was a child and bullied by her stepmother and sister. In order to form a marriage policy, the Saimori family betrothed Miyo to the supernatural being Hisado Seika. Although this person has outstanding talents, he has a cold personality and has been broken off by many of his fiancées. When Miyo first arrived at Hisado's house, Seika treated her coldly. However, the kind-hearted Miyo gradually moved the indifferent fiancée.
