As a lot of other people have stated, the beginning of the drama and the end of the drama sometimes seem like completely different animals. The beginning has us learning about the two sisters and the diametrically opposed viewpoints and struggles they have...and somewhere around the middle it turns into the story of the two male leads and a dark, troubled past in their respective families. It's interesting how this series was billed about a story of two sisters, when to be quite honest Gong Mi (Gong Shim's older, 'prettier' sister) is all but written out of the drama as a whole. I wonder what happened there? Either way, the actors had excellent performances all around, though I admit I would've liked to see more of Gong Mi in the entire drama, even if as the predictable foil 2nd female lead. The music was probably what stood out the most to me in this drama, and the two male leads. That being said, this was fortunately a case of a drama more or less losing its way down the line, but not failing to be entertaining all the same. I still greatly enjoyed this drama and would likely recommend it to someone...though it's not likely to be on my top ten.
