This kind of drama with thrillers, suspense, violence & action is what I watch most. I used to watch the Mexican & Colombian Narco-Series, which had many episodes & seasons. This is the first K-Drama I've watched that includes violence. I enjoyed it a lot.

Nobody is a Saint here. If you're a saint, this job isn't for you.

Park Joon Mo is a police officer. He is arrogant, has a lot of attitude & also cunning. His fighting between right & wrong. His hurt face whenever Jung Ki Chul mentions his wife & insults him. Ji Chang Wook was awesome in this drama, he killed it with his performance.

Jung Ki Chul is a drug dealer. He is smart, not like other gangsters who are always temperamental and don't use their brains. He calculatively takes his next steps. It's a pity that his this kind of move faded in the end. Wi Ha Joon did a phenomenal job. Loved his acting. First time watching him & he left a good impression.

Jung Ki Chul & his friend's brotherhood, loyalty ended because of power-hunger & money. I didn't like how his friends used to address him as 'Sir' when they were all partners. I think this is the biggest reason why their friendship turned out like that in the end.

Yoo Eui Jung is an elite officer who is related to both of them. She doesn't have much of a scene time. I mean her betrayal affected Jung Ki Chul the most. But without her, the story would've been the same.

Loved Lee Hae Ryeon. I didn’t know it was BiBi. Her acting is good.

Loved Park Joon Mo & Lee Hae Ryeon. Their kissing scene uff. She ate him.

Love Jung Ki Chul walks with his gang. So classy & stylish.

The fight they had in the narrow alley with other gang members is also my favorite scene.

Discomfort between Park Joon Mo & Yoo Eui Jung after seeing each other with someone else.

To the length of madness, Park Joon Mo went in episode 9. It was crazy but also awesome.

Lee Hae Ryeon & her bodyguard relationship & what he did for her at last.

I wish Park Joon Mo & Yoo Eui Jung had talked to each other about all of this in the end, then it would've been better. I mean they won't go back to being what they were, but at least talking would've helped even if it was about a breakup.

Loved the execution of fighting scenes.

If you're okay with violence & narcotic stuff, then give it a try. You may like it.
