The setting and atmosphere of two dramas are alike. Both contains action scenes and involved large company frauds. In "Healer", the male lead hides his real identity and pretend as someone to get the job done. In "Are You Human Too", a robot pretends to be the chaebol who is in a comatose to save his inheritance. Both use likely high technology equipment / gadgets in their mission.
At first sight,those 2 don't have much in common.But,the doppelganger/robot clone is evident in both.When watching Crowned Clown,I get a similar feeling I got from Are You Human Too.Both shows have a "bad" and a good character played by the same person,complicated family history,people helping the good character adjust and genuinely caring for the "bad" character too.The attempt to survive in different settings due to identity switching in order to protect someone is also part of both dramas.
