I like the characters in this drama and the plot of the story but it was to long. As the younger sister gets in trouble and is suppose to have martial art skill that we see very little of it. The older sister is more reserved and refine and tries to keep in control the younger sister. The writer tried to throw some curves that to me only upset does who where watching the story. The evil aunt that could get better assassins and even her maid was a great assassin but the emperor could do nothing. The aunt that can get away with all the bad things and then leave it to her son who was a good person but turn bad because of jealousy. No! to far fetch for me. The obsess maid that was in love with her son, did all the dirty work and did not care that she was treated badly, To far fetch. The romance is cute but sad with all the couples. The ending left me very upset. After you made us watch 40 episodes and we were enjoying the Emperor and the women (Older Sister) he love finally be together you ended with them separating. What, hoping for a second season? The actors did a good performance and most of the story is enjoyable, but be ready for disappointment.
