School Scandal Grading by Sexual Exploits Unlocks Futures

Yukio High School introduces a radical new policy: students must engage in sexual activities to pass their classes, with grades determined by the number of encounters. As the rule divides and pressures the student body, alliances and relationships are tested. Rina and Hiroshi, initially hesitant, find themselves navigating the intense demands of the system, questioning its morality while striving to succeed. The school becomes a hotbed of competition and tension, where personal boundaries are pushed to the limit.
