I had to write a review because the only review here really does not do this drama justice. This has to be one of the best thought out revenge dramas I have ever watched. When this drama starts out, it does make you wonder when the turn of events will happen because of all the evil that takes place; but when it does (around ep17/18), it is a welcomed change of events. The story line is awesome, the music is awesome, the acting is awesome and I only gave it a 9 because of the lack of chemistry in the romance department. Rewatch value is a 5 because when you rewatch it, you will pick the episodes you want to watch instead of watching it from start to finish. Overall, I never thought this drama would survive 30 episodes but it has. There has never been a point at which I would want to drop this drama or not watch this drama. I can honestly say that I just may buy it once it comes out on DVD.
