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. She was a confused wife, but when her husband asked her to help him evaluate her 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.
