Only drama that i am giving this 9.5/10 rating out of all i have seen

Ha Ji Won and Ji chang wook acting was best thing in whole drama
struggle that shown by ha ji won to choose King over the emperor not because she loves him but because she can't be with empress, cause she blame him for her fathers death, how empress Ki give up her love for her fathers revenge and started to love king over Ji chang wook
those who says king was her first love
think about it who she was true to herself it was ji chang wook character
with king she has to behave like a lady but with ji chang wook she can be herself, And the love ji chang wook shows for empress ki was so incredible
how empress ki accept her feelings towards Emperor at end,
at end she admit to love the man that was reason for her fathers death and was one who killed her ex lover with his own hand, she still loves him knowing all that was great
it is only drama where you can believe her genuine feelings for both of man she love both of them. and most impressive was that it was hard to say if she love one more then other because she shows her love for both of them...was genuine
