Dear Brother (1991)

It’s Nanako’s first day at Seiran Academy, a prestigious all-girl’s high school famous for its exclusive and elegant “Sorority.” Only ten members will be accepted this year, and competition is fierce! Despite seeming fairly unremarkable on the surface, Nanako is selected as a member – instantly making her a target for her jealous and angry classmates. But the bullying doesn’t stop Nanako from forming friendships with the three most popular students, and even falling in love.
