This drama was so promising, great cast and great acting! They had set it up very well, with the plot and the characters, their goals and plot twists. But more than half way things started repeating and going in circles. The worst of all is the ending, a complete let down. They swapped the characters, trying to give the bad guys some sense of good or justice, when I can't see how they deserve any. But that's not even that bad, drama's do that all the time. The worst part was that one of the main characters didn't even appear in the last episodes! That and the character changes completely made the ending disappointing. I was expecting for something at least half decent. So my review is, this drama started off really well, and I do recommend the first half, but half way through it becomes not worth it.
