The Story is soooooo good.... for a revenge drama the story might sound a cliche of revenge due to betrayal blah blah blah that might make it so predictable and uninteresting to watch... But the twists on the story makes it so exciting to watch that you just keep on going just to know what will happen next... From the beginning to end this drama gripped me...For me there was no slow pace in this drama, there was no moment for me that I was tempted to fast forward the show because it was boring.. The story alone interested me enough to finish it from beginning to end in no time. The characters were well played by the actors and actresses that portrayed them... (Disregarding the fact that Joong ki is an eye candy XP ) The Cast has given proper feeling to the characters... I hated some characters when it situation calls for that person to be hated, sympathized if it was needed and things like that.... There are even times that you might even shout out to the characters just because you are carried away by their performance (ok maybe you won't but I did XP) The Music is great too... It matches well with the scenes that it sometimes makes me cry.... All in all this is one of what I can say is a must watch for everyone and you won't have trouble rewatching it cause it is simply an amazing drama.. I watched it twice before proceeding to another drama and sometimes I rewatch my favorite episode just to reminisce on the story :-)
