Mei Hayashi is a half-Japanese returnee and the most popular girl in school. I am a typical middle-aged man called "old man teacher" by my students. I never dreamed that such a popular girl would take an interest in me. From after-school hours to Christmas and eventually graduation, I struggled to keep my vow never to touch a student. However, her overwhelming proximity broke my will. This is the story of a year and a half spent in a secret, addictive relationship with a translucent beauty. Despite the guilt, the arousal won't stop—where will this path lead a disgraced teacher?
