Both dramas have a similar feel and story, and portray a love story between a human FL and a ML who is an AI. There is a scene in both where the ML rescues the FL from a fire, and both MLs end up being forced to leave toward the last part of the drama but return in the last few minutes for a happy ending and reunion with the FL.
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.
