Though this drama could easily have been scored an overall 10, I chose a 9 simply because of the ending. It's not a bad ending, though I personally didn't like it, but it's ambiguous as hell and I HATE that. It leaves you wondering what really happened... and after such a great emotional drama roller coaster, don't do that to the viewer! Summary: The story and acting are top notch, and the acting so much so that you fall into the characters without realizing you've done so. I'm lucky that I started watching it after all episodes aired and could do a 16 hour marathon or I might have had a heart attack. The ability for the story and actors to blend so well that you feel punched in the gut at times, cry like a baby, and smile through the tears is amazing. Few dramas achieve that this well. For most of the drama, the first 13 or 14 episodes, there is nothing incomplete and it just flows right along. I'm not sure exactly what it is, but about ep 14, it feels a bit off, but it still moves you. The OST is fantastic and matched the moods perfectly. As for the cast, Jo In Sung and Song Hye Kyo had some of the best on-screen chemistry I've seen in a while. Song Hye Kyo played the tortured blind heiress like she grew up that way and you felt like you really were watching Jo In Sung grow from street thug to respectable human right in front of your eyes. There were other really great actors/actresses in this cast, but these two just captivated me. All in all, this movie was put on my top 5 favorite list for a reason. It has it's flaws, the ending being the biggest in my opinion, but jerked my heart strings like a professional guitar player.
