As much as I loved Kim Hee-ae in The World of the Married, I really disliked her character Hwang Do Hee here. I don't buy the sudden change of heart and having a conscience afterwards. Her actions were the same in my view - just a different master/motive.
I usually like dramas where I can root for the lead - but halfway through, I was still lukewarm to Hwang Do Hee.
Other thoughts:
-The story telling and pace of the drama was ok, and I didnt feel it was dragged out.
-Acting was quite good from most characters
