With this kind of Neo-noir plot, the drama had so much potential. But they wasted it with other irrelevant sub-plots. It felt like ep 7 - 14 were just fillers and the action only picked up from episode 15, the one before the final episode. If the writers had just stuck to the original plot about Yeo Joo's blood thirst for cheating men, Woo Sung, his affairs, the rich girl and Yeo Joo's spy assistant; the drama would have being so much more satisfying because the viewers would have got what they promised. Instead they inserted some ridiculous political plot and wasted half the time with that. The sub-plot was interesting but still irrelevant to the main purpose of this drama. The fact that they just created more and more suspicions about everyone and did not give a single clue about anything until the final episodes made it all the more infuriating. The writers really didn't make things better with that cliff hanger ending. This show started off with a good outline for the plot, but the take away from this drama would be to be weary of the writers and their next projects. Plus the acting was great from everyone which was expected. However Yeon Woo needs more practise as she was lacking in expressions.
