hello! I am looking for dramas where rich ML (chaebol) asks FL to become his Mistress because of their status difference or he knows his family will never agree but FL refuses, ML chases her and is obsessed with her. Eventually  they fall in love and have HEA together . Please help recommending something like this. Thanks. 

I mean what could be something for you that would fit this somehow is World of the Married. thoguh you'd only truly understand why it fits in the last episode? So yeah. It is an absolute AMAZING drama but yeah.
and then maybe also Before We Get Married

The classic show with this trope is "Secret Garden". I'm sure you've already seen this, but maybe it's time for a rewatch?

It seems that this trope was trending a decade ago. So there will be many older dramas in my list. 

I second the Secret Garden recommendation, that was the first that came to my mind.

Bridges of Love  but settles for being  (semi spoiler:) her friend  for a while (while still pining for her). Really obsessed hero.

Something about 1 Percent 

The Master's Sun 

The Greatest Love I'm not sure he quite offers her to be his mistress, but he feels like he's too good for her anyway.

My Lovely Sam Soon  Very much like Secret Garden (the couple dynamic)

Dreaming of a Freaking Fairytale I'm not sure about this one because I've not seen it yet. But it seems like it.

The Beauty Inside this one is more egalitarian, as they're both on the same wavelength as to where their relationship stand.

Cruel Romance This one is high angst with (semi spoiler:) many people dying by the end.

Are You the One has a similar theme. ML is already engaged via an arrangement made by his mother, but he has fallen for someone else so he thinks about making her his concubine. But as they talk, he realizes this wouldn't work for her. It's even more messy because she has lost her memories and thinks ML is already her husband. They live as husband and wife already but she doesn't really know his true identity. Nor does he does hers.
