It is my favourite historic drama. It has a very strong/historical story and background, the plot is very intertwinted (very positive note). Nothing has been left behind or untold. I loved the 20 episodes lenght it gives you all of the explanations.
The costumes and colors of the drama are magnificient, beautiful and very accurate.
The dialogues are very deep and touching.
The OST is one of my favourite and is perfect for the script.
The actors are ALL 10 stars, touching perfection.
I love every minute of this romantica-historic drama and gives you a very full spectrum of real life emotions; it touches every kind of relationship: family, lovers, secret lovers, friendship, loyalty, traditions, cultures.

P.S. I’ve rewatched 3 times already.
Loved it.
