As of late i haven't been watching many airing dramas, not like i used to. So when i heard about this drama and read it's synopsis i knew i had to wait for it to finish before i even considered watching. All i can say now is DAMN!......I'm actually glad i waited because it would have been stressful waiting week to week for new episodes. With that said i gladly gave it a 9 over all. The story was new to me in many ways. I'm not a fan of cop dramas for many reasons, main reason being kdramas tend to have the dumbest cops in all of tv history. Gladly, this drama didn't have that. The cops were decisive, alert, smart, and most of all they put two and two together. The story was also a great mystery, i was guessing up to the last episode about who done it and honestly surprised when info was revealed. Adding a cherry on top, physiological thrillers are my best friends late at night; who needs horror when i can watch something like this. Jang Na Ra and Seo In Guk did an amazing job as the leads, there was enough romance to satisfy my craving but it never took away from the main story which some writers don't know how to do. The supporting cast brought more greatness to this drama adding to the story by giving comedy, sorrow and irritation at the right moments. Music was on also a selling point, I enjoy a good OST and will download it and even research the artist. This drama was no exception. The rewatch value is low because idk if i would want to watch it again. The suspense and mystery behind it is all reveled and that takes away from the greatness of the drama..for me. But i would watch it again with someone who hasn't seen just to enjoy their reactions. I would most def recommend it. Whether you like mystery thrillers suspense or just looking for a good drama this should be on your plan to watch list.
