An extraordinary school life.
The setting is Soyuki Academy, a school city located on a single island. It is an integrated school covering everything from kindergarten to high school, and its isolated environment has allowed for the development of a unique educational policy. 90% of the students have attended since kindergarten. The academy features a unique "Partnership System" where a male and female student form a partner contract. They are ranked based on their grades, internal reports, compatibility, and the duration of their partnership. Ranks range from D, C, B, A, to S, with S being the highest. For example, housing is assigned by rank: D-rank gets a 2LDK apartment, C-rank a 4LDK condo, B-rank a 6LDK luxury high-rise, A-rank a detached house, and S-rank a sprawling mansion. Other differences include the cafeterias and available services. Higher ranks also correspond to higher social status. Guest and Abe have been partners for 10 years, placing them at the very top of the S-rank. Other students react to them in two main ways: either with awe and fear of the unknown, or by worshipping them like gods as fans. The two live together in a massive mansion.
