It's great . Full of Action Pain Thrill Politics Romance . Every bit of emotions u can get from it . Must watched. Ji Chang Wook has done his role just awesomely. The turn of the stories are also great. Ending is nice too . For starter it's very addictive . U can't wait for next episodes. The music or all the tracks are very nice they r suitable to the drama . It's the best one for me as far I have watched. The fighting scenes are also great . The connection between past and present is done very well here . Yooah is just awesome in her role too.
