If Ms. Thao is the most mentioned name in Vietnamese lectures about lewdness, in Japan, that title must be given to Kamihata - a female high school teacher. But there is a difference between these two characters, Ms. Thao has an ambiguous relationship with the students, and the character in our movie has a relationship with the janitor. Ever since she asked for a job cleaning in the school, the janitor had always looked at her with an evil thought in her mind that she had to take her body. The opportunity finally came, when there were only two people left at school, he played a trick to force her to have sex with him, shy but happy, so she could only move slightly to resist. After that time, the relationship between the two got closer and closer when the two of them made an appointment every afternoon in a closed area to be able to perfectly carry out the clumsy love.
