The first time I watched this was back in 2015 when it came out, also when I discovered my current favourite actor (Park Bogum, versatile king !!). I did like it a lot back then and I like it even more now, it's definitely worth it! If anyone asks me for a thriller criminal drama, this is the first thing I would recommend.

Many people had a problem with the main female lead's actress, and being honest, she's not my cup of tea either, but she was not an obstacle for me not to enjoy this drama. The cast was phenomenal, from Kyungsoo's cameo to the police team, everyone did a great job, special props (again) to Bogum for building his character amazingly.

Now, as for the story/plot, that's what I liked the most. Most criminal/law dramas are "there's a culprit that scapes and wants to kill one of the main characters, they work together to find him and finally put him in jail". This was not like that. The characters were so clever, genius, it kinda gave me Death Note vibes sometimes. The development of the story was good, and it was all because the amazing and clever mind of the three main characters (Hyeon, Min and Lee Junyeong). And I'm so so glad the romance was not a main focus here because it would've ruined the whole thing, and instead, that they focused more on Min and Hyeon's relationship. The ending was also amazing, not cliche at all and you definitely do not see it coming. So many things happen on episode 16 that is impossible to predict what will come out of the whole thing.

To sum this up, this drama was genius and not cliche at all, I enjoyed the whole thing and was not disappointed by the ending, though there's one thing that kinda bother me, it's not that "big" and I'm still okay with the way they wrapped it up.

100% recommended, please give it a try, you won't be disappointed.
