A middle-aged man and woman drowning affair that begins in the bathroom - a wet, secret room

It's been three years since I married my husband Kazuyoshi, whom I met at work. Yuri wants to have children soon, but her husband, who is busy with work, is reluctant to have sex at night... One day, Kazuyoshi meets his former boss, Abe, on the roadside. After failing to do business that he started independently, Kazuyoshi hears that he lost his home, and encourages him to stay at home until he calms down. However, the real reason Abe became independent from the company was that Yuri, a woman he had always loved, was married.
