The love story between a high school boy and his girlfriend would be beautiful if it weren't for the presence of the intern teacher, Ibuki Kanon.
Because he is a special student and the worst in class, he often has to stay after school for tutoring sessions with the lewd teacher, Ibuki Kanon. Gradually, their relationship became distant in terms of status but very intimate emotionally to the point where the girlfriend felt jealousy and had to cheat on him with another guy.
Upon discovering this, he was incredibly angry and sad, and during such times, she would come to encourage and comfort him, which led to love blossoming between them. Over time, their love grew deeper and more intense, to the point where they engaged in secret sexual encounters right in the classroom and library without any embarrassment.
