I have nothing to say. I am overwhelmed by this drama. The ending made cry. THIS is the best thing I have ever watched. The concept,the acting, the nail-bitting suspence, over the top action sequence,the rivalry,  the emotion, the chemistry between the three main characters, the devilish acting of the villain, the cinematography, the fictional story, the..........................................I can go all day, all night saying about this drama but it may not be enough. This should be the best drama ever created. I have watched many drama including asian and netflix series. No drama touched my heart this much. The torture  scene were acted like the victims are really being tortured. The acting of each character was beyond oscar worthy. And the main characters : Sato Hiroshi and Kimora: the chemistry between them, the rivalry, the bromance turned revenge was the main attraction of the show. I know this is one of the most popular Korean drama but I think its still underrated.
Lastly, IF U HAVEN'T WATCHED THIS DRAMA SHAME ON U, GO WATCH THIS U DONT KNOW WHAT UR MISSING.
