Cast

The wife of a female teacher who decided to go on a preliminary inspection of a school trip. Due to her cost cuts, her companion is only one male teacher. Although there is no problem in the couple's relationship, from the perspective of her husband, who has a prejudice against her teaching job, saying that "there are many people who are unproductive and insidious", it was uncomfortable for teachers to stay overnight on business trips. For Miho, who is not interested in anything other than her husband, it should have been a baseless worry, but her sensible colleague quietly hits Miho with her insidious sexual desire.
