This is a M.U.S.T W.A.T.C.H!
If you have doubts about this drama because you don't like harem fights, then you should continue to read my review because I'm also not very fond of those.

I'm a big fan of historical dramas but I don't like the useless fight of dumb palace women and usually historical dramas have a lot of that.
Well, guess what! This drama is centered on the fight inside the harem but[ BUUUUT ] it is completly another thing. The characters and behaviors actually make sense and the female lead isn't the typical kind and silly girl that needs someone to rescue her. SHE IS THE REAL DEAL! I love how cool, brave, loyal and smart she is. I swear I've never seen such a good character in a drama.
The story is amazing, the characters are not typical. Each character actually has reason, there aren't evil and good characters, there are only complex characters.
Usually when I watch a drama with harem fights, it feels as if a lot of characters are so unreal, so thoughtless and they are focused on one thing, like a bot in a game. In this drama, the characters feel real. Of course there are also few characters with less importance who aren't as complex as the others but even those are realistic.

Now then. What I loved the most in this drama are the characters. I really loved some of them and I bet everyone who watches this will love at least 1 or 2.
The plot is really really good and the story doesn't leave you frustrated in any moment. I think the story is flawless and with the help of the amazing characters, it takes this drama to my top 3 dramas.
The music was also good and I would actually rewatch it after some time!

11/10!
