Class de Otoko wa Boku Hitori!?: Kawaii Anoko-tachi ni Kakomarete

Machida is a timid, inexperienced young man who finds himself transferred to an all-girls school. Thrust into an unfamiliar environment where he is the sole male student, his quiet nature makes him an immediate target for attention. Among the many girls surrounding him, two classmates named Rio and Mao take a particular interest in him, singling him out and making it difficult for him to avoid their advances. The situation quickly escalates as Rio and Mao begin teasing him relentlessly. Pressed closely against them and overwhelmed by their persistent flirtation, Machida reaches his absolute limit. Unable to control his reaction amid the intense provocation, he embarrassingly climaxes right there in a classroom full of female students. The sudden incident leaves him completely mortified, yet remarkably, only one person appears to notice what has just happened. Rio is the sole classmate who observes Machida's overwhelming moment of vulnerability. Rather than drawing further unwanted attention to his embarrassing predicament or alerting the rest of the room, she quietly steps in to assist him. Taking charge of the delicate situation, Rio discreetly escorts the flustered boy away from the crowded classroom and leads him directly to the school infirmary to recover.
