Nine Puzzles

They have the same overall premise, such as-
1. One of the MCs being a suspected killer in a previous cold/unsolved case from a decade or two ago
2. One MC believing that the other is the killer, while struggling to prove it
3. Teaming up between the suspected killer detective and the one that suspects them
4. Old case resurfacing

In both dramas a child witnesses the murder of a family member that is a police man and joins the police force to find out what truly happened to their family member. They investigate the crime and discover that their colleagues may know more than what they first appeared to know. Both dramas play around with every character being grey and not clear if they are good or bad. Both have very similar results for the culprit.

Both dramas revolve around a police woman that ends up investigating a case that appears to be connected to the murder of a family member. In both dramas there seems to be a cover up of going on and she herself is at one point questioned in regards to her own involvement. Both dramas revolve around an ambiguous group of people where one can never be sure if they are now good or bad.

I highly recommend you to watch this drama. ???????????????
