My wife Mineko heads to her husband's parents' house with her son instead of her husband who hurts his back and can't move. Mineko wasn't worried at all because her son was supposed to go with her to the destination. The son was a stepchild of her husband, and the two were not related by blood. On the other hand, my son, who has always looked at Mineko as a woman rather than as a mother, couldn't hold back his excitement when he found out that his father couldn't accompany him. I changed my plans to stay at my parents' house and decided to spend the night at a nearby inn. Seeing this as a perfect opportunity, his son tries to persuade Mineko while they are out drinking.
