I love Lee Jong-suk, which was what prompted me to watch this drama. Medical and Romance are two of my favorite genres. The first episode was so captivating - it felt like a complete movie. The acting, the North Korean plot line was so perfectly done I only wish the other episodes were the same. It kind of started to get a little bland as it progressed, but it was still very interesting enough to me that I watched the drama all night, episode after episode. Overall I'd say it was a good watch. The cast was pretty good in my opinion, and the comedy aspect was okay.
