This is an excellent melodrama with a awesome cast in Song Joong Ki and Moon Chae Won. Just the two of them makes this show a must-watch, and they do not disappoint with their versatile and excellent acting. Story: The story got me hooked right from the 1st episode. The revenge theme was not new on its own but the way it was written in this drama makes u feel on the edge of the seat. You will find yourself empathize with Kang Ma Ru and Seo Eun Gi and even with the evil casts of Han Jae Hee and the evil lawyer. I love the ending (was not expecting it) but like what some of the other users' reviews wrote, it took a while to figure out what happened. On hindsight, had it been any other endings...it would have been really cruel. Acting/Cast: This is a perfect 10 for me. Song Joong Ki's acting was a revelation especially coming right after his performance in Sungkyunkwan Scandal. The emotion roller coaster he portrayed in this show was perfect. And, I really love Moon Chae Won, my favourite Korean actress after watching Princess's Man. The range of emotions she portrayed as Sun Eun Gi was unbelievable and she once again showed us how good an actress she is. Music: The ost was excellent in evoking the emotions of the show. It just makes the great show even better. Rewatch Value: I don't usually rewatch drama so that's explain my rating. If ever I were to rewatch, its because of both the leads. Overall: This is easily my drama of the year for 2012, now that 2012 is coming to an end soon. Without disclosing too much spoiler, the following quote from Maru in one of the very touching scene really sums up what this drama is all about: "I hear the laughter of my friend, my sister,and my love. They are part of the most beautiful, delicious,and fascinating dream in the world, that I can ever dream. Afraid that if I open my eyes, I'll wake up from my dream, so I can't open my eyes in fear. For this beautiful morning, thank you for gifting it to me. I won't be greedy and ask for more. I won't expect any more. Right now, I am happy"
