first of all lets start with the ost, "love is at war" is pretty awsome. next is doc......wow daebak i just fell in love with him. havent seen him anywhere else but i would like to get to know him better. his personality fit his face and character, he was perfect role for that. the rest of the cast was great too they all did their parts well. the romance was to die for i rewinded several times coz this man dint smile yet he just bedded her with flying colors. my other favorite character was safari. he was just a busan boy with bad rep. i felt for him by the very end and liked him. the show reminded me of city hunter esp at the shootouts and the end scene. the reason that it dint get a 10 is coz of the story line with the director min. i mean how many freaking undercover cops were there..it just became overrated and lost marks. it was too much. its a great show with alot of cliffhangers so be prepared for the ride.
