On weekends, Kana's friends and their wives would come to visit our house. We had even talked about moving in because it would take a long time. Apparently they're moving in next month. It's spacious and the rent is twice as much as ours. My wife was excited to see the house, but when they offered to rent it to us, I felt Ito to go alone. So we came up with the idea of ​​"swapping couples" that was popular on TV. At the time, I never thought I would have such a nightmare.
