One day, her husband, an office worker who works hard late into the night, came home with his boss, Managing Director Kudo. When I heard about it, I heard that he was going on a local business trip to a branch office outside the prefecture starting next week, and for some reason, Managing Director Kudo had asked his subordinate's wife, Kaho, to accompany him on that business trip. The wife was confused, but when her husband asked her to do it to evaluate his promotion, she reluctantly agreed. Then, the next week, at a hot spring inn in the mountains, her boss asked her to entertain him in an obscene manner.
