There was a guy who was quite old but still not married and didn't even have a girlfriend. While his parents were urging him to get married and were not happy with their son. Afraid that his parents would be sad and worried, he lied that he had a girlfriend and would bring her home to meet them this weekend. He scratched his head 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. It sounded crazy, but because of their friendship, the other guy agreed and Natsume was very willing. And that night, they made love like real husband and wife after the introduction dinner.
