The love story between a male student and his school girlfriend would be beautiful without the appearance of intern teacher Ishihara. Because he is a special student and the worst student in the class, he is often tutored by the lecherous teacher Ishihara every time after school. Gradually, the relationship between the two became more and more distant in terms of status but very close emotionally, so much so that the girlfriend became jealous, envious and had to have an affair with another guy. Knowing this, he was extremely angry and sad. At times like these, she came to comfort him and then love happened between the two. Over time, their love grew deeper and stronger, to the point where they both made secret love affairs right in the classroom and library without the slightest hesitation.
