The first thing that popped into my head was the classic shojo story Rose Of Versailles, which conveniently has a 2025 movie remake on Netflix

This story is from a manga from the 70s, there’s the 1979-80 anime TV show, a 1987 animated movie.

I’ve never watched it myself, but it’s one of the most famous bishojo stories out there, so there should be something good about it.
