Crime, drug dealers, politicians, cops, corrupt cops, backstabbing, lying, trickery and gangsters - you can guess why this is called 'Cruel/Heartless City' right? ;) It's dark and mysterious and sometimes your mind will shout "yeah right!" "No way!"at some things the people will say or do... It was a good drama, I wouldn't say it was the best I've seen but it's definitely worth watching ;D Cast: Jung Shi Hyun "doctor's son" (Jung Kyung Ho) a mystery man, during the first few episodes I was wondering how I could possibly like this "drug king" b/c if he is bad I have to hate him right? Well, that all changed by episode 4 - I was like oh DAEBAK now I CAN like him ;D His character was dark, cold, kind, loving, as honest as he could be, he was my favorite out of everyone <3 Han Soo Min (Nam Gyu Ri) is a newbie cop who goes undercover to try and catch &quot;doctor's son&quot; but ends up falling in love with him instead - their romance was sweet <3 Ji Hyung Min (Lee Jae Yoon) a pretty good detective I'd say, I liked him but I also got mad at him a lot b/c of him being so determined to catch "doctor's son" b/c of his own misunderstanding. Kim Hyun Soo "Soo" (Yoon Hyun Min) the "best friend" & "right-hand man" of "doctor's son" - I enjoyed watching "almost" (lol) every scene he was in ;) Lee Jin Sook (Kim Yoo Mi) I didn't really care about her that much, she was "whatever" to me, she played her role well but I was a bit grossed out by her so called "love" for someone whom she practically raised since he was a kid... O.o Music: "Hurt" by Kim Yong Jin (Bohemian) - Now I first heard this song WAY before I decided to watch this drama - so I already knew this song by heart. But it is my favorite song for this drama - I love it and played it several times before & after finishing this ;) Re-watch Value: 7.5/10 - It's a good drama that I might re-watch for Jung Kyung Ho's role (I loved his dark eyes & persona in this drama).
