Miss Pendleton is quite good if you like historical.
The translation from korean to english is really interesting. English is not my native language but I think it uses an old version, I was quite intrigued.
The art style is beautiful, and I haven't finished the manhwa yet but I like the story too. The female lead is an independent 25 years old woman, and wants a career for herself. She's a girl's girl and helps others find marriage partners.
I still have to learn more about the male lead but from the comments I've seen he's quite patient and charming.

Can’t for the life of me get into straight romance stories so please recommend something really really good! Historical, modern whatever just one with adults please
