I had been running around for work and before I knew it, I had missed my chance to get married. However, fortunately, I was able to marry a wife who was too good for me, both beautiful and well-mannered. My wife, Yoshiko, was remarried, but the life I spent with her and her son, Takashi, was happy every day... One day, as usual, when I returned from work, I found that the sheets I had just changed were stained. Although I felt a strange unease, I didn't realize at that time that this was the beginning of betrayal...
