Secretly super rich?

Any drama where the story goes: boy meets girl, girl and her family finds class and status really important while the guy values love, so he tries to win the girls heart while pretending he's not rich, or something similar. 

Or maybe something else where the guy is a complete philantropist who makes a lot of money but is still sort of poor because he continusly gives it away or whatever.

Well I'm looking for something like that, thanks.

Office Girls, rich guy hides his identity because of a contract with his father and works in his own business as a low level employee and gradually falls for the poor girl ( who lives in the same building and also is a coworker ) with all the typical good traits . Girl does not know his identity, keeps helping him and falls for the poor version of him.
