I loved it until they starTed doing my girl Choi Yoo Jin wrong but aside from my biased misgivings about this drama it was really good. Plot: a runaway mercenary' a girl whos mother was murdered and has been held captive since a young age' the girls father running for president and his wife the cold hearted master mind. Mercenary caught at the wrong place at the wrong time and is then later teams up with the wife to take down a common enemy. Buy then yhe Mercenary and girl fall in love with each other and desiderate to join efforts to take down the wife. Story of mistrust' betrayal ' cunning schemes paired with awesome fight scenes and heartfelt relationships. Not to mention a good bit a comic relief. Apparently the story was changed since the audience wasn't having the desired response to the characters (no sure how true this is but I do see it being very possible) The ending was very bittersweet for me and I am happy about maybe 75 percent of what happened in the last two episodes but I'm biased to my fave character Yoo Jin.
