Let me start of by saying this drama is not meant for everyone. It's a modern suspense/thriller drama, with a supernatural element making it refreshingly different. My favorite part of the drama was the gorgeous cinematography paired along with the music. It gave the show some visually stunning scenes. The plot, however, is the drama's biggest flaw. It is super confusing, especially in the beginning because you don't know the girl's origin story. The main character is a mysterious lone wolf, who seems set on helping people along her journey. The more you follow her along, the more gets revealed. You have to watch the drama for at least 5-6 episodes to give it a chance. While a romance subplot does exist, there is little emphasis on it. It wasn't a problem for me, but I can see how many people would have an issue with this. The main reason to watch this drama is for the cinematography, supernatural elements, and for the badass female lead who kicks butt!
