The wife of a female teacher who decided to go on a preview of her school trip. Due to cost reduction, only one male faculty member will accompany you. There is no problem with the couple, but from the perspective of the husband who has a prejudice against the teaching profession that "there are many unproductive and insidious people," it was unpleasant for teachers to travel overnight. It must have been a melancholy for Miho, who is not interested in anything other than her husband, but a sensible colleague gently hits Miho with her insidious lust.
