This is one of the best movies I've seen lately. I never expected I would laugh this much watching a movie with such a dark theme. I can agree that the plot has been used before when it comes to police university students getting tangled up in a criminal case. But I think the movie shows some character development when you see Ki-joon go from being unsure about wanting to become a police officer to find pride in helping people and appreciate the work that the police do for the people and for the victims.

As I mentioned before, the movie has a dark theme. What I mean by that is how the crimes surround the subject of human trafficking. It shows how cruel people can be towards others, selling their friends to make money, selling their organs without their consent and making them victims to crime. As cruel as it seems, this is the reality, this is actually something that happens to this day. So I think the movie is doing a great job raising awareness of the subject.

Apart fom that, it also shows what runaway children needs to go through. Many of them are victims to domestic abuse or has experienced bad things in their household. Running away from it doesn't mean it makes it easier for them. They have to stand on their own feet, finding a place to sleep, bringing food to the table and suffer from the fear of being sent back to the cruel place they ran away from.

On the other hand, it was great seeing Park Seo Joon and Kang Ha Neul being like brothers in this movie. They fought together, suffered together and succeeded together. They did a great job showing the character's youthful craziness, their life struggles and their dedication to improve, not for themselves, but for others.

I had a fun time watching it and I recommend you to see it yourself. It is a great movie to watch with your friends.
