Pretty much everyone was watching it when it aired, but I was quite worried that I might disappoint myself if I have too high expectations. Nope, that didn't happen. I loved it so much that I had to binge watch this in only 3 days.
The storyline itself is quite complicated in subject matter, but they handled it very well. The characters were well developed, and every moments, even the small events were precious to me. The chemistry between the main couple was definitely no joke. The only thing I'm subtly sad about is that person who goes far far away that they can't return (spoiler but didn't name it lol). Still, in my heart, they have a happy ending too, that they met and live happily ever after.

P.S 1: Ri Jung Hyuk set my expectation from man unreasonably high
P.S 2: I hope for reunification real soon.
