This drama had some great actresses and the story line was nothing but a drama-fest. I couldn't believe how ruthless Na Young was but, she really started to grow on me around episode 10 and i found myself rooting for her. I know - that's awful but, she should have given some of her guts to her sister. I don't think she was in on scene where she wasn't crying!!!
There must be a season 2 to this drama because, if not, the ending was the worse I ever saw. Too many issues were left open and not resolved. That is the one thing I like about Korean dramas; they have a definable beginning, middle and end. This one left too many questions and was not satisfying. That's why it only receive 3 stars...
