Who's the Keyman (2018)

Actually, everything is roughly about the same. It's just the cast, the storyline, and the way they interpret the concept is different. So if you like this series or Who's the Murderer, you will definitely like Crime Scene. Crime Scene is the original and Who's the Murderer and Who's the Keyman is the China adaptation of it.

Both are investigation related shows with very similar production styles. The main cast is very similar between both shows. The major difference is that Who's the Keyman investigates non-murder incidences.
