I first heard about her for RICH MAN POOR WOMAN too. I was excited to watch it, but it was one of those that I waited so long for all the subs to be released so I could finally watch it, but by the time I had the complete show I didn't have time to get to watching it. I still have it on a hard drive somewhere.
So TECHNICALLY my first drama of hers was UNNATURAL and I loved it, so it may push me to finally get around to watching RICH MAN POOR WOMAN hahahaha
