I've been delaying to watch this drama influenced by the low popularity and low score given. But I have to say that after watching a few episodes, my impression started to change at the same time that it was growing my interest to know how it will end this story. I think the plot is quite interesting and original. Despite of the common topics like orphan girl with a dark past trying to climb on society and making the rich guy fell in love with her, etc. The development of the characters was brilliant and get the spectator to empathise with them and their dramatic relationships. I specially liked the way these characters were presented in a more wider view than simply bad or good people. For me, these two sides of the personality made them more realistic than in other dramas where normally are classified as the bad or good girl/guy. I disagree with other opinions about Park Yoochun saying that his acting it wasn't good enought. I think he did a good job playing the role of a rich guy who knows nothing about the real world and how his relationship with the woman we fell in love making him to learn about the bitterness of love. Not mentioned that Lee Da Hae was amazing in her interpretation and made me to love and hate her character through this frenetic net of lies. The other main leader, played by Kim Seung Woo it was also great and I loved the fact that It was significant in the plot and not just something to create friction between the other two main characters. I really recommend to watch this drama and not to be influenced by rankings but with a critical and open mind.
