This is typically the type of story you used to find in old Hong Kong crime movies with men and brothers fighting each other in a story of cops, crime syndicate, mafias, and undercover operations. It was usually very romanticized, violent, and dark and in the ends, the outcome left no one unhurt. This drama totally follows this path.

1/ STORY
The story is rather simple. A cop accepts to do an undercover operation for a very personal reason. This leads him into a world of gangsters where bad guys also have their values and laws which make them not so bad and good guys are not always so good but have deviant behaviors and make questionable choices. He navigates in this and meets a local boss, and they develop an understanding and a friendly bond throughout time. The problem is that two women enters the scene, and they will make the two men question themselves, who they are and who and what they want and love. The result in the end is a terrible outcome for everyone.

2/ WHAT I LIKED
- The bonding between the two male leads and the bromance despite an uneasy personal situation in connection with the FL.
- The individual character development of the ML and of the SML. As I said, they are very romanticized but there is a clear beginning, a transition and an ending that is well told.
- The action and violence. I would have liked a little more of them.
- The ML and SFL. Their interplay was endearing. Cop guy and gangster girl trying to handle each other.


3 /WHAT I DID NOT LIKE
- The schemes were not so well made. I questioned some events that looked a little bit too simple or unrealistic.
- A little too much of "Who has the bigger balls". But I guess that's inevitable in a gangster's vs cops story.
- The last 3 eps were a bit underwhelming with some plot holes and far-fetched events that make them look rushed and inconsistent.

4/ CHARACTER - ACTORS
- Joo Mo: a simple and dutiful guy who becomes a gangster to bust a drug ring but he makes encounters that change him, his values and vision of thing and make him question his job. I liked the character and JCW was good portraying him.
- Ki Chul: simple guy with big dreams but a romantic who will question himself and try to change things for the best or the worst? Endearing despite his bad actions. WHJ was convincing too.
- Eui Jung: Some say she is useless in the drama. On the contrary. What she does or do not do triggers most of the tragic events. She is the main cause of everything. Im Se Mi. Second time I see here after True Beauty. Totally different. Good acting.
- Lee Hae Ryeon: the crazy and fun character who reveals herself not as hardened as expected. Superb job from the actress.
- Hwang Min Gu: The brute cop. Too much screen time for him and his antics. But his demise was fun.
Not a lot of noticeable characters beside these.

5/ OST: I enjoyed it bit nothing memorable.

6/ REWATCH VALUE: Probably rewatchable but a little too dark.

7/OVERALL
It is darker and sadder and more violent that expected. The schemes and counter schemes kind of drag the plot at times but overall, it is a good story. I would say the mafia and crime thing is not the most impressing or the most important. It is the personal situation and development of each of the main characters. From their point of view, it is a tragedy. A well told one. I totally recommend this drama. 9/10 . I do not give 10 because of the few telling flaws of the last eps but It is a good drama.
