Nobuko's loneliness had reached a critical point. After the birth of her only son, Takashi, her light-hearted husband became more and more disinterested in the work of the couple, and she fell into a sexless state for a long time. Nobuko can't stand it and is violently disturbed by masturbation. Takashi, who happens to be passing by, sees Nobuko's lewd and lonely appearance and begins to worry about wanting to help her mother somehow. "I wonder if I can comfort her mother..." Nobuko, who touched her Takashi's kindness, intersects even though she thinks it's not good. Nobuko was completely fascinated by Takashi's matchlessness... She couldn't leave Takashi even for a moment.
