KDrama where main female lead is rich?

Does heiress even happen in KDramas? lol

Anyways, looking for any modern-time Kdrama where the MAIN female lead is rich or at least have tons of money. Often they are portrayed as middle-class working women, and most of the time - poor. 

I ask for modern time because historical dramas have queens/princesses so they're "rich" in those xD

A Man's Story (and it depends how you define "lead", but one is from a wealthy family and the other starts poor but becomes rich)
Yong Pal

Awesome!
Thanks for the recommendations guys :D

I will check out that Thai Drama, been looking to get into those anyway.

Thanks, that looks like it's worth checking out!

High society
Couple or trouble
My fair Lady
You who came from another star
Queen of the game
Innocent man

@antonin that drama was disappointing, High society i mean. UEE and sungjoon had zero chemsistry ???? thus i went and loved the 2nd lead more. I loved UEE in hrr other dramas, mainly marriage contract, ojjakyo brothers, fool's love. 

anyway in addition to those suggested, I wanna mention:
1. Lovers in Prague - she was not a chaebol but she was the daughter of the president, so that counts.
2. Happiness (I Am Bliss) - this is a long family drama, and the 2 daughters were chaebol. And they had romance stories to 2 poor guys.
3. The k2
4. East of eden
5. birth of a rich man
6. i love Lee Taeri
5. cloud Staircase
8. Mr. Duke
9. Dr. Kang
10. 49 days

long lost princess and hallyu stars,
Stars Lover and A Love to kill
My princess

Thank you for the suggestions!
