Romance where the ML is considered ‘beneath’ the FL

I’m not sure how else to explain this. Basically the ML has a lower standing in society than the FL. Or he’s poor and she’s rich and there’s angst and stuff because of that. I’m interested in couples that have that dynamic. Can be main couples or secondary couples, as long as they have that dynamic. Modern or costume drama are both fine. The only one I can think of that has this and I’ve seen is Hao Du and the princess from The Long Ballad. I loved their dynamic and I have liked dynamics like this in kdramas and Western shows too.

Thank you in advance!
