Wife Mao lives with her husband's father, Takashi, at his family home. To save money for their own house, she spends her days alone with Takashi while her husband is away working. Though initially hesitant, Mao diligently tends to Takashi's needs. Over time, Takashi harbors hidden desires for her, eventually giving in and reaching out to touch her body. One night, as the house falls silent, Takashi creeps into Mao's bedroom, clings to her pale skin, and takes her for himself.
