Heaven and Demon

High school teacher Aoki has always avoided the school infirmary, harboring an unexplained aversion to its resident doctor, Mr. Tengoku. However, his resolve is tested when he is compelled to visit the clinic to discuss a student who frequently skips class. During their very first encounter, Tengoku effortlessly sees through Aoki’s carefully constructed facade as an exemplary educator and greets him with a knowing, enigmatic smile. The doctor casually reveals that he has been observing Aoki ever since the teacher was assigned to the school, hinting at a deeper, unsettling interest. As they discuss the truant student, Tengoku sharply points out Aoki’s underlying naivety before suddenly kissing him. Overwhelmed by embarrassment, the timid teacher finds himself unable to resist or pull away in the moment. This unexpected intimacy acts as a catalyst, triggering long-buried childhood memories and forcing Aoki to confront the authentic self he has spent years hiding behind his professional mask. As the walls of his carefully maintained persona begin to crumble, Aoki is left to navigate a disorienting emotional landscape shaped by Tengoku's piercing insight. For a man so accustomed to playing the perfect role, the ultimate question remains: will this awakening lead him to heaven or plunge him into hell?
