When Tsubaki and Takuro got married, they were supposed to live with Tsubaki's father-in-law, "Yoshio." Tsubaki, who had a good impression of the kind Yoshio, started a life of three after getting married. At first, her father-in-law seemed serious, but in reality, he was a pervert who stole her underwear, set up hidden cameras all over the house, and masturbated while secretly filming Tsubaki changing and having sex.
