Stories with prestigious/private/catholic school setting, better if it's a boarding school, as I love dorm life and relationships between residents/roommates! And I especially love if the dorm/school buildings are old/western style, like old British colleges, for example. I really love the whole atmosphere and aesthetic of these stories and the students' classy uniforms (especially black ones!).
Elite School, Academy, Dormitory, Student x Student/Teacher, Classmates, All-Boys School etc.
