This series is truly breathtaking and keeps you in the edge throughout the whole run.

Every actor in this series have delivered in the most impeccable manner and no one falls short in delivering. Yet, a special shout-out to the two main actors (Shin Ha Kyun and Yeo Jin Goo) must be given for their baeksang worthy performance. The bromance are intricately developed and I like how their relationship develop throughout the series.

I truly love this series because there are no unnecessary romance or any unnecessary theme, and the darkness in the story is carried out without being cheap or silly.

It drags during the first episode but after that it has been nothing but a gift that keeps on giving. I will definitely rewatch this series, and as much as I'm wishing for another sequel, the series has given us a truly satisfying ending.
