One day, the husband of a salaryman who was working hard for an upcoming promotion came home with his boss Nakata. When I asked him about it, he was going on a business trip to a branch office outside the prefecture from next week, and for some reason, his subordinate's wife, Miho, was sent by Director Nakata. accompanied him on that business trip. . Miho is confused, but she has been asked by her husband to evaluate her promotion and she has no choice but to accept. And the boss requested obscene entertainment at a mountain hot springs inn that I visited the next week.
