The happy life with Yu, who attacked many times and got married, changed completely because of his junior, Koichi. During the lunch break at work, Koichi and a woman talked, and he boasted that a married woman was the easiest to drop. In addition, my wife Yu also said that she could afford it, so I was filled with anger and ran my mouth to persuade her. And a few days later, he invited Koichi to his home and left him alone with his wife for three hours. After that time, I rushed home and completely believed the two people who said that nothing had happened.
