This drama is different from most regular dramas. It takes place in a different region than popular dramas and plunges us into the world of drugs and crime.

Story:
The story is pretty well written and the action and event sequences are thrilling. Sometimes an explanatory scene is missing for certain things but it remains a detail. The plot, the course of events, everything is well balanced.
The first two episodes, which serve as an introduction, would have deserved more clarity (apparently several scenes from the beginning of the drama have been cut) but remain correct in their introduction of the characters and the universe of the story.
The story really starts at the end of Episode 2 and from there it's a roller coaster ride. We live, like the heroine, the immersion in a sad, hard, cruel and dangerous world.

Characters:
The FL who, at first may seem like a hothead, will quickly find her way into our hearts with her ability to blend in with the surroundings, her resourcefulness and her badass attitude. She is different from the usual FLs. She knows how to fight, knows how to use her mind, has a lot of nerve. She also has a lot of empathy, strength of mind, and can be cute and innocent in certain situations.
ML meanwhile is more mysterious. It is difficult to truly understand who he is since most of his thoughts are not accessible to us at first. However, we are captivated by his charisma, the sensitive heart we feel under the mask he has created and, at the same time, just like the FL, we fear him and his intentions.

It's a drama that wants to portray life undercover and what it means to investigate. Therefore, the focus is on the FL. We also follow her whole team. It is the story of these police officers, of their courage, of their difficulty in arresting criminals that is told.
The bad guys are also important because the FL works with them and you have to feel all the danger that it represents to work in this environment.
The drama achieves the feat of humanizing the people living in this environment. There are the rotten ones, of course. We often have little empathy for them. But there are also those whom poverty and lack of perspective has thrown into this world. I applaud the writers for portraying human misery and the fact that we have to destroy drug trafficking for these people too, so that they have a chance.

Recommendation:
I highly recommend this drama to those who like action, police, crime and mafia stories. This drama is definitely worth it. If you like to try another kind of drama, go watch it! Its unique proposition in dramaland, its focus on a badass and resourceful FL and its subject made it a drama to be seen.
On the other hand, not everyone will appreciate this story given the subject and the way it is treated so don't waste your time if you don't like police drama or crime drama.

OST:
The OST is really good. It is not use at each episode like in most dramas but sublimates the scenes in which the songs are used. I have had chills and tears more than once thanks to the OST.

Conclusion:
It's one of the best dramas I've seen. From start to finish, I was glued to my screen. The story is interesting and the characters are well written and endearing. There is everything: action, investigation, romance, social painting.


What I liked the most:
- A strong and resourceful heroine who improves over time.
- A charismatic and enigmatic male character.
- An intense immersion in the world of crime.

What I liked the least:
- A lack of clarity during the introduction of the main characters.
- The dubbing of the voices, due to censorship and a rewriting of certain dialogues, is sometimes not perfectly synchronized in the beginning.
- Some somewhat confusing editing choices.
