This started out really strong but I almost totally lost interest by the end. One of the most intriguing part of the drama for me was the portrayal of North Korea. It was very nuanced and I learned that one of the screenwriters was a defector. Other than the interesting setting, the strength and appeal of the drama lay in the lighthearted and heartwarming day-to-day life of the main couple while in NK, before it was bogged down by all the other plots. Side character Gu Seung-jun stole the show the minute he showed up. Why did they kill him off ? and in such a lame way lol. I really struggled to like the heroine at first. She is very wealthy and her disdain (played to comedic effect) of the NK citizens' much less affluent lifestyle read too much like classism... It was a bit uncomfortable. With that said, the main couple were really cute and sweet and the hero was very good at doing the intense and wistful stare. Overall, very predictable and cliche, but lighthearted and has some heartwarming moments. Great production values and music and great wardrobe for the cast too.
