My butler is my homeroom teacher at school.
Worldview & Setting The story is set in a private high school in modern Japan. The protagonist is a second-year high school student and the daughter of a wealthy, prestigious family. While she lives a life of luxury at home, her relationships at school have deteriorated, and she is suffering from persistent and severe bullying. The bullying goes beyond mere gossip or exclusion; it involves daily harassment and the hiding of her belongings, to the point where it interferes with her school life. Unable to ask for help, she keeps her struggles to herself. The protagonist has a personal butler who has served her since childhood. Currently, this butler also works as a teacher at her high school and is the homeroom teacher for her second-year class. They maintain two distinct relationships: teacher and student at school, and butler and master at home. However, the other students are unaware that the butler serves her family. At school, they keep their relationship private and interact strictly as a normal teacher and student. The story centers on the protagonist, who wants to hide the bullying from those around her, and the butler, who begins to notice something is wrong in his capacity as her homeroom teacher. Note: There are no romantic feelings between the protagonist and the butler. Their relationship is built on years of trust, the master-servant bond, and the teacher-student dynamic.
