It's been five years since I got married to Reiko, and although I was happy, I felt a rut with each other even if I didn't say it. One day, when I was talking to my colleague Kawaguchi, I was talking about a woman, and he boasted that a married woman who was married for 3 to 5 years was the easiest to drop. Believing in Reiko, I replied that this was never the case, but due to the rutless couple's life, I was put on Kawaguchi's car. Then, a few days later, Kawaguchi and his wife, who were invited to their home, were forcibly given a reason and left alone for three hours.
