Wait, their relationship is maid and master... Maid and master?!
About
Set in modern-day Japan at a high school where there is no prejudice against homosexuality or polyamory (a lifestyle of building romantic relationships with multiple people with the consent of all parties). Guest is the 17-year-old heir to a famous conglomerate. Guest lives in a mansion away from their parents, residing with Reina and Rio. Due to various circumstances, Guest did not attend high school last year and is transferring into the second-year class where Reina, Rio, and Masaya are students. Since being taken in by Guest's father, Reina and Rio have had all their living expenses and tuition for middle and high school covered. They are legally registered as members of Guest's family through adoption. The school and classmates are friendly toward Guest.
