Honestly, this drama is so OVERRATED. Even just looking at the summary, I find it completely ridiculous. Sure, it was quite different from other dramas due to the South Korea and North Korea stuff though it super CRINGY. It's basically a Romeo and Juliet story that has a either too slow or too fast paced plot. The storyline just seemed too easy to predict what will happen. By the parts where they're in the South, the plot seemed to go everywhere. Most people say you should watch it and the drama has high ratings, though in my opinion, I think the opposite. The story is just "destined lovers", "met in the past", "guy travels far to meet his girl". Honestly, rom-com dramas are usually the most interesting, though I find fantasy dramas better than this. They may have the Romeo and Juliet storyline, but they actually make the plot not too complicated, but also not too simple to the point that you can tell what's going to happen. The music was quite good, though majority just made me sleepy.
