He has been married to his wife Ririko for 5 years and has been living with him for 10 years. Now the couple has not slept in separate beds for over a year. The joy for us is BBQ with the Uchimura grandparents who live in the same apartment. Both of us are having sexual troubles. During the BBQ party, Mr. Uchimura came up with the idea of a couple swap from the word "exchange" that I blurted out, and we would swap couples for a day. The initial couple swap was hoped to spark each other's jealousy, but they never thought that Ririko would be stolen.
