If you watched the first episode and considered dropping like I did, don’t do it! During the first 5 episodes the show expects you to get used to the titles, names, relations, and family of main character. Nothing too big will occur as far as I remember. It gets REALLY REALLY good soon after. Interesting characters are introduced, several sub plots are established, and most importantly the romance begins to bloom.
The main character isn’t a flawless, know-it-all. She is a girl who self taught herself whatever she could, and is clearly lacking. Family conflicts and discussions make a big part of this show, like every historical drama ever, so if you hate that type of dramas this would be difficult to watch.
I usually avoid C-dramas due to the trashy acting but this one was easy on the eye in this matter.

Absolutely recommended!
