“Ryo” is a construction site supervisor at a small construction company in Tokyo. A year ago, I married a younger woman, Mizuki, from the same workplace. He is not rich at all, but he lives a happy life without any inconvenience. However, “Mizuki” not very fond of sex, and perhaps because he has no nightlife, attends a meeting called the “Wife Presentation Round” at the invitation of a man named “Nakada” that he met. on a certain website. It is a perverted circle where members offer their wives. One day, “Ryo” being “Nakada” squeeze. “I have to do it with my wife, so give me your wife too!”
