I love, first and foremost, a really good storyline. If a lead couple has amazing and sizzling chemistry, sometimes they can over come the plot to make it highly watchable, but those dramas are rare. This is a very richly textured drama from episode 1 to episode 49 and I've enjoyed every minute.
Because it's not a perfect 10, there are minute flaws and the one I'd like to point out is the lack of love scenes between the main couple. They are very, very good actors in their characters but, for some odd reason, have very little passionate scenes. At one point, a pair of parrots simulates their climatic kiss moment and I found this truly bizarre.
Other than this one small detail, this is a phenomenal story, acted with finesse by all and a production that allowed me, as the viewer, to be immersed. Definitely worth every episode of time (minus the parrots).
