I was going back and forth for a while, trying to decide what rate would be appropriate for this drama. Then I finally settled on an 8.5. Let me first start out talking about the story. This is a story that starts out all too familiar; a common story that involves a rich guy and a poor girl falling in love, evil mothers and switching identities. However,. I love that they added supernatural elements to the plot to change this typical story into something more. And there are some family secrets and plot holes that are not revealed for a very long time. The acting was great! I didn't really expect much at first. But, I think Lee Hong Ki's acting had improved greatly. What impressed me was not Lee Hong Ki in this drama though, It was the female lead who was able to pull off two completely different personalities so well for two different characters. The whole time during the show, not once did I feel like it was the same actress. Furthermore, I can feel the emotion from these characters as they endure anger and sadness. Props to everyone who created this great cast! The music did not highly impress me enough to where I can really say much about it, but there were nice traditional sounds during the scenes of the past. As much as I liked this drama and was pretty much hooked through to the very end, it is one of those shows that I may not watch again for a while. It wasn't my favorite drama, but it was very very good and is a must watch if you haven't already seen it. I would definitely want to watch this again some day in the future!
