A certain guy is quite old but is currently unmarried and doesn't even have a girlfriend. While his parents strongly urged marriage and expressed dissatisfaction with their son. Afraid that his parents would be sad and worried, he lied that he had a girlfriend and would take her out this weekend. He ruffled his hair and then thought of a way, he would go to his best friend's house and ask his wife Natsume Saiharu to pretend to be his girlfriend. A proposal that sounded crazy, but because of friendship, the other guy agreed and Natsume was also very willing. And that night, they made love like real husband and wife after their debut dinner.
