A fellow romance anime lover (^^)? I looked through your list and have seen some good ones :3. I’d recommend “say I love you.” I have other recommendations too, but this one is a pretty good one in my opinion (^^)b.
You might like The Rose of Versailles and Akagami no Shirayuki-hime if you haven't checked em out yet. It'll take a bit to get used to the art style of Rose of Versailles since it's a late 70s shoujo but the story is pretty good!
I hope you find others though!
