This is the first time Minami has visited her husband's home, where her husband was born and raised. But it seems that her in-laws are arguing, and they don't talk to or care about each other. But Satoshi said it's probably because his father often drinks, so Minami it. The next morning, her father-in-law said he was sick, so Minami stayed home to take care of him while Satoshi went to meet his childhood friends. Minami's father-in-law offered her a jelly dessert, and while she was eating, she felt extremely sleepy. When she woke up, she realized that she was being sexually assaulted by her father-in-law and had reached climax without realizing it. Because he had recorded the video of their sexual activity, Minami had to comply with his desires. Her mother-in-law found out about but couldn't do anything because she was also having an affair herself!!!
