Best series I have seen since The Serpent. Great story, script & actors. Keeps you on the edge of your seat & super entertained. I laugh, cried, made me think & was emotionally touched. I never watch violent movies but here it was not gratuitous, the plot is too smart, witty & not really fiction. Bravo to all the Koreans who took part on this production. The lead is actually an amazing actor, contrary of what someone else wrote in an other review.
