I really don't understand why people don't like it. The story is really good, a little complicated at first but after you try a bit more you start liking it a lot, and it doesn't take that long to understand. All actors were perfect they did a very very good job, the couple was really good and they did a great job. The production was amazing one of the best I have ever seen and the songs were really good. Honestly try watching this drama, and one little thing that you must understand is that you have 2 worlds. 1 is the korea that we know and the other world is were you still have a king but in the modern year, using their old costume on specif times.
