I have seen several KDramas and to this date, this is now my #1 tv series...edging my erstwhile favorites Crash Landing On You and Vagabond. This show has everything from Romance, Action, Suspense, Treachery, Humor and Tragedy. It's a Tear-jerker too from episode 2 up to the end of episode 20...You would need a lot of tissue or better a towel since there's a lot of crying for 19 episodes. The OSTs are so emotional and touching that whenever I hear IF I and I BELIEVE in a scene, my tears begin to fall..The show has the Greatest Love Story and the best last episode and ending..It's the first time I've seen all the cast but I immediately fell in love with them all, such a good chemistry and acting by the whole ensemble..You feel as if you are swayed and a part of the royal court....some of them you love, some you hate and a combination of both....but if I will surely protect my "HIS" Majesty the Crown Prince Lee Hwi...EUN-BIN PARK became one of my instant favorites and hearthrob.... she's so charming...I hope there will be another good show like this. LOVE IT..
