"Disorder in clothing is disorder in the heart." Kana-sensei, who always sternly preaches this to her students, was a model teacher recognized by everyone at school. As the class representative, being praised by her was my greatest joy, and to me, Kana-sensei embodied the ideal educator. However, from the day I witnessed the shocking truth hidden behind her serious facade, all common sense was overturned. The moment we passed each other on the stairs after school, what caught my eye was Kana-sensei without underwear. For a second, I thought it was a mistake, but the next day after class, when I followed her, I saw her indulging in exhibitionist behavior. Contrary to her usual strict image, her transformation as she unleashed uncontrollable desires made me gasp. The face of an educator and the hidden other face. The drama woven by this contrast captivates viewers without fail. What seems like an ordinary school life suddenly transforms into a thrilling secret world. Kana-sensei's duality delves into the deep psychology of humans, drawing one in irresistibly. This work goes beyond mere entertainment, encompassing profound themes that approach the essence of humanity.
