Ah.I love that show.I have watched hundred of kdramas and if I have to choose number one then I will rank this as my no one.mind blowing,natural acting of kim soo hyun ,and also the actor who played young king,sorry to forgot his name ,I have watched him in hotel de Luna and eat ,lovek,kill ,makes this show a tremendous success. Kim soo ,you are a master of crying.you have PhD in expression and emotions.I bet ,every viewer will cry a lot with him.I am not spoiling but just for emotional viewers that show had a happy ending.
