I was busy with work and missed the wedding time, but luckily I married a beautiful and talented wife, who is too good for me. His wife, Rieko, has remarried, but she and her daughter Taka are still happy every day. One day, as usual, when I got home from work, the sheets I had just changed were dirty. I felt a strange unease, but I didn't realize that this was the beginning of my betrayal...
