Sakura Haru Girls Academy, a school where girls from noble families gather to learn. The protagonist was hired there as a janitor. But that was just his public face. His true role was that of an "actor."

All the students are celebrities. Scandals are strictly forbidden. ──Therefore, the female students sexual desires are greater and more twisted. To portray their "ideal man." That was the duty assigned to the protagonist.

The first student was "Saeki Ichijou." She is a student council president, excelling in both academics and sports, from a prestigious family that has even produced prime ministers, a person destined to stand above others. However, she harbored a sexual fetish she couldn't tell anyone about.

The protagonist takes on a role to satisfy her. As her ideal man... her "Master."
