Shinnin kyôshi: Nomotomiho: Chiniku no urajugyô (2003)

Kinko Shimazaki (Miho Nomoto), the new English teacher at Yugiri High School, witnesses her senior teacher and fiancé, Kawamura (Rin Sakiyama), kissing. He has asked for her, but she declined, stating her desire to maintain a fit physique before marriage. During class, student Kazuko Okawa (Kae Tanimoto) displays SM magazines on her desk. Kinko confiscates the magazines and reprimands Kazuko, who reacts defiantly, leading to an accidental slap. To discuss Kazuko, Kinko meets with Kawamura, who unexpectedly takes her to an SM show pub in Roppongi called "Sugar heel." He explains that Kazuko's father is a major school donor with political connections, granting her special treatment with no repercussions. Kawamura then advocates for Kinko, encouraging her to fight for a healthier school environment.
