In a boys' high school, a persistent rumor warns that any student from the lower social ranks who remains alone after class will be forcibly stripped of their virginity. Literature club member Saitō Shūji, who occupies a modest position in the school's rigid hierarchy, one day notices a scar on the wrist of Mikami Tomohiro, the undisputed top of the caste. A silent exchange—a promise to keep the discovery secret—passes between them. Soon after, Shūji stumbles upon Tomohiro in the act of carrying out the very "virgin hunt" the rumor describes. This chance encounter forces the two into a precarious, overlapping world of secrecy and desire. Their relationship deepens through a series of tense, intimate encounters that blur the lines between coercion and genuine connection. Over the course of the story, the pair navigates the pressures of school life, hidden vulnerabilities, and the growing bond between them. The narrative arc follows their journey from that first witnessing of the forbidden act through the emotional and physical complications that arise, culminating in their graduation and the choices that come with leaving high school behind.
