So I'm not a fan of non-Autistic people cast in the role of an Autistic person. Imitation of gestures or manners of speech are seriously not fun to watch. Even worse is when an actor who formerly played the part of an Autistic person is using the same mannerism in another role to just createan odd personality. That's cruel.
Also, the dialect is so over-acted that it hurts my ears, and Korean is just my ninth language.
I know I must sound rude , but I think this story was concocted to utilise Park Eun Bin's Attorney Woo fame.
