Incest: "Mother, this house is insane."

The curse of incest, which lasted for the third generation of parents and children, led to the collapse of one family. She is a younger sister who has been jealous of her body since she was a child, an older sister who couldn't stand such a family and went out of the house but seeks his own son's body, Natsumi, and Kazumi, a daughter of Teishi who continues to have a relationship with her brother who is different from her. When three women began to live under one roof, a party of forbidden incest with love and hatred was held.
