Ryo is a site supervisor at a small construction company in Tokyo. A year ago, he married a younger woman, Mizuki, who works in the same office. He is by no means wealthy, but he lives a happy life without any inconvenience. However, "Mizuki" doesn't like sex very much, and perhaps because she doesn't have a nightlife, "Ryo" is invited by a man named "Nakata" whom she met on a certain website to participate in a meeting called "Wife Submission Circle". . It was a perverted circle where members offered their wives. One day, "Ryo" is pressed by "Nakata". "Since I had a fight with my wife, give me your wife too!"
