A few years after remarriage... Mai was spending happy days surrounded by her loving husband and kind son. In the early afternoon, a young salesman came to the office and handed him a business card with the name "Koji Ito." It was the same last name as the son of her husband who broke up with her! Although she doubts her, she gently accepts her salesman's wish that she doesn't know her mother as compensation for her separated son, Koji. She gradually escalated her desires...the moment the salesman took off her pants, there was some evidence that she was Koji...
