This series, although I wasn't sure what to think of the secondary and tertiary couples, was definitely worth watching. I thought that the characters were well built, and the chemistry well thought out. It also has an interesting story, that I; personally speaking, haven't seen elsewhere. Sure there are probably other dramas alike to this, but does the story flow as well as it does in this drama? Although I'm often not very fond of some of the History series due to the coupling, or stories. I thought this worked extremely well. And I would never hesitate to rewatch this, even if I know the entirety of the plot. Definitely worth watching.
