I'm not sure if this drama was written with the thought of a second season or not, but it for sure should get one.

The greatest thing about this drama is how small the cast is and how natural and well built are the interactions between everyone. We only have three characters in the special missing person team: Soo Hyeon, Dae Yeong and Seo Jun and it makes perfect sense. Special team that has to be mobile while they take cases from many different places, why would there be more people? With high profile cases like the ones they dealt with, they would simply work with local police if they needed back up.

I truly enjoyed the set up. The dynamics between the characters were good - every one of them had a distinctive but realistic personality and they all played off of each other well. I also want to praise Seon Jun’s character. They could have easily made her hacker and nothing more. The girl has a brain of her own though. She does not just wait to “google” whatever the detectives ask her, she does the investigation too and helps solve cases.

Sadly, in my opinion, there were some mistakes made in the planning. The first case the group has taken was so amazing, interesting and attention grabbing, all the rest felt a bit flat. From Kang Ha Neul’s performance, to the “saw” like setting of the crime scenes, up to the mind games and plot twists - everything was perfect. All the rest though...they were still good, but nowhere near as good as the first one.

The writers also strongly hinted at a big mystery around Soo Hyeon, but as the drama progressed, we got barely any new information about it, and the attention to it was brought back only around episode 7. It was never properly explained nor concluded. You could say this plot hole was deeper than the Mariana Trench. It would be far better if we got some small hints here and there. I felt like the writers forgot about the subplot they themselves introduced.
Concerning that plot line, the writers could have played a bit more into the forming relationship and trust issues between Soo Hyeon and Dae Yeong. The culmination of the “bonding” was not as impactful as it could have been and how they dealt with the aftermath was quite poor.

Even with some of the flaws I saw in the drama, I still would say it’s a show worth checking out. The overall plot was well paced, the cases seemed realistic (for the Korean crime shows), most of them had nicely planned plot twists, some more, some less predictable. The production value was fine, some typical crime show mistakes like looking for clues in a room with really dark sunglasses on (sure he saw a lot with them on), but not big enough to make anyone frustrated, annoyed and angry.

That ending though… it was something else.
