Kanna and Sumire are teachers at schools in Tokyo. There was a student, Kaoru, who had been absent from school for over a year in the class they were in charge of. This happened because he was worried and made a home visit. Kaoru was a villainous man who kidnapped a woman in the street and turned it into sexual activity, took a picture and sold it to a darknet. First, a violet is laid down, and Kanna is attacked by the poisonous fangs of his family! !! And it started with the days of sexual hell that was extremely gruesome.
