I just finished watching this show and what can else can I say about it apart from the fact that it's a tearjerker, a comedic and blissful romance...
What I love about this show is hard to list out because of the huge number, but I must agree on the fact that the familial, and friendship bonds in this show are so raw that it'd just bring a teary smile to your face. The way they show the contrast between the North and South in every aspect is just so gorgeously detailed that it never fails to bring out my empathetic side for the North Koreans. There's a small aspect of dark humor underlining the entire show that you'll have a great time figuring it out.
The main leads romance is so cliche yet so pure and enjoyable to watch that the cliche aspect wouldn't even stop you from liking it.
The story of the second leads is just as good as one would expect it to be and I loved all the side characters. Even the bad ones.
The only drawback of this drama is that it is HIGHLY unrealistic. But that just made it even more enjoyable to watch so I'm not in queue to complain.
I will definitely rewatch it one day.
