Yuki-chan is an aspiring teacher, an intern trainee. I became a teacher because my childhood friend's parents, who were like my older brothers, were teachers when I was a student. I have forgiven my childhood friend's older brother, but he is at this school where he has been assigned! After school, Yuki-chan's childhood friend asks her to be a photo model... Gradually, the demands escalate, and Yuki-chan's teacher life becomes a day of naughty sexual harassment.
