Here's some of my faves:
- My Happy Marriage (shoujo romance, basically a Cinderella retelling in the Meiji era with supernatural abilities, it's really sweet- the main character goes through horrible abuse but finally experiences love and happiness with the love interest)
- Sugar Apple Fairy Tale (shoujo romance, fantasy setting dealing with fantasy racism/slavery)
- Yakuza Fiance (seinen romance, yakuza princess & prince being set up by their families for a potential arranged marriage, good action and comedy)
- Heaven Official's Blessing (actually a donghua aka Chinese anime, it's an adaptation of a danmei novel series. BL romance with cool supernatural action & adventure)
- Beastars (edgy zootopia. but it's cool as fuck)
- Puella Magi Madoka Magica (needs no introduction, it's just that good)
