A guy is quite old but currently not married even without a girlfriend. While his parents urged to get married and show dissatisfaction about his son. Fear of sad and worried parents, he lied that he had a girlfriend and would lead to debut this weekend. He crumbled his hair and thought of a way, he would go to his best friend's house and ask his wife, Natsume Saiiharu, pretending to be his girlfriend. A proposal sounded crazy, but because of his friendship, the other guy was also well and Natsume was also very good. And that night, they made love to each other as husband and wife really after dinner.
