I was so excited when I watched the trailer of this show, and the first 12 episodes were really up to my expectations. The producer started off this drama well, with many areas explained yet unfolded at the same time. Many parts in the first several episodes were funny also, and at the same time, thrilling. This made me have higher expectations towards the ending. However, I was disappointed by the writer. She could have just stick to 16 episodes because the last few episodes were just too draggy. They only started to cover the loopholes during the last two episodes, which were quite rushed for the ending. I won't want to comment further about the romance also because I was really expecting for more romance to bloom after watching the first 12 episodes, yet again, not up to expectations again. Probably the writer has intentions of not focusing the romance part in this drama. I was also expecting for more bromance scenes between the P4 and Detective Seo but I will just leave it as the writer wrote. I was impressed by Lee Seunggi's acting and I can say that he is one of the few male actors who have improved tremendously over the past few years. His every crying scene makes me cry too. He can really pull off this character well - a cold guy yet fragile heart who still needs people to accompany him. Overall, the drama did not turn out to be what I really expected due to the last few episodes, but it is still worth watching. (:
