The drama is good but the ending is not satisfying. Solution lasted for less than 5 minutes as if they didn't consider the 16 episodes prior to it. There are many unresolved cases like the murder of Hye Jin, the case of Kwang-hyun, the search for Kang's son, etc. I was left hanging. This better have season 2. But please, dear writers, let us savour the victory of the protagonists 😮💨
