One day, Koharu, who has lost her parents, witnesses the marriage of a beautiful fox in a black pine forest where she has wandered. However, the bride, who disrespected the human Koharu, became angry and suddenly broke the deal. Koharu hurriedly ran home, but what was waiting for her was a troublesome relative.
It was the fox bridegroom who had been broken up that appeared in front of the relatives who were talking to Koharu about selling herself. The bridegroom, who calls himself Genko Ozaki, proposes to pretend to be Koharu's husband in exchange for help from his relatives.
