Oushun Jogakuen no Danyuu

At an elite academy for daughters of wealthy families, a man is hired as a janitor but secretly serves as a male performer to satisfy the students’ suppressed desires. His first assignment pairs him with the proud student council president, Ichijo, who publicly demeans him yet becomes submissive during their master-slave roleplay. Their encounter serves as both psychological release for her and part of his paid duty to prevent scandals. Afterward, the two return to their separate daily lives, while the staff hint that another student will soon require his services.
