Once there was a guy who was quite middle-aged but had not yet married and didn't even have a girlfriend. Meanwhile, his parents were very eager for him to get married and expressed their dissatisfaction with their son. Fearing that his parents would be upset and worried, he lied that he had a girlfriend and would bring her home to meet them this weekend. He pulled his hair and thought of a way: he would go to his best friend's house and ask his friend's wife, Natsume Saiharu, to pretend to be his girlfriend. A proposal that sounded really crazy, but out of friendship, the guy agreed, and Natsume was also very willing. That night, they made love to each other as if they were really husband and wife after the introduction dinner.
