If you like Shakespeare or medieval fantasy this is a great manga to read. Requiem of the Rose King is based off of (or at least heavily inspired by) the story of the Wars of the Roses. The characters are interesting, the story is sad but compelling and the art is top notch. Richard especially is interesting because intersex representation has little to nothing at all and I'm glad it's put on to a character that really grows throughout the series. Some would call it BL but it's a lot more then that. It's hard to put down the book and each val ends on the best spots (and when I say best I mean worst because I really want to know what happens next). My only big complaint is that the story can get extremely confusing at times and the age gap between Richard and //spoiler// is pretty big and it can get kind of uncomfortable. There are also some panels where you do not want people looking over your shoulder. But besides that it's an amazing read and Def would recommend.
TLDR: great manga with beautiful art but be ready for heartbreak
