I truly enjoyed this drama, and now that I finished it, I have withdrawal symptoms. Honestly, this show has everything that I enjoy:

(1) An intelligent female lead that doesnt take crap from people (no Mary Sues here) ;
(2) A male lead that is willing to do what needs to be done to reach his goals (Anti-heroes represent!);
(3) A strong chemistry between the leads (NO duck kisses to be seen);
(4) A couple that teams up and solves their issues quickly (those that scheme together stay together);
(5) A story that has not fillers (missing the mandatory annoying second couple, yay!); and
(6) A very happy ending (in many ways *wink wink*).

Point number 6 was very important to me and thankfully SOKP delivered, I had been burnt many times by C-dramas and there is nothing more frustrating than investing 40 plus episodes on a period piece and getting rewarded with tragic or lazy open ending. So kudos to the cast and crew, this drama was very entertaining, two thumbs up from me.
