Drama recommendations with a rich woman and poor man

Can any one recommend me a drama where the female lead is rich or comes from a rich family while the male is poor. They are plenty of dramas that have the opposite, I thought this might be more interesting  to watch. Also, k-dramas only. 

Thanks!

Secret Love Affair

Money Flower- well the ML isn't exactly poor but kinda depends on other people... kinda lol

1+ High Society & Yong Pal

Others that almost match up:

Prosecutor Princess - Rich FL & poor SML (her initial interest)

Heartstrings - I think FL was from a wealthier than average household. The description on MDL says "born into a prestigious family". Idr anything about the ML

My Little Princess (C-Drama) - Rich FL & poor/average ML with a rich SML

The Lover - in one of the couples the female is not rich but in a better financial situation than her jobless bf whom she takes care of

Ms. Perfect - has a rich SFL

And What Happens to My Family? has a side couple of a male character who's a doctor but comes from humble beginnings & a female character who's the daughter of the chairman/CEO of a hospital

 Czakhareina:

I think for both cases of noona romance, the younger male were actually secret Chaebol heir  ut something made themdecide to live a very humble life rather than the life of luxury: Witch's romance park seojoon was actually taking up medicine under his father hospital then quit, while Dalja Spring's LeeMinki was actually a lawyer but wants to be a chef. 

Oops, you're right. My mistake. Sorry. 

(Although maybe you should put this information as a spoiler ... well, I suggest)

Thank you so much to all! I’ve only watched innocent man so far, which I loved. I’ll definitely check out some of the others.
