People try to "kill" the MC, and he pretends they're just playing; commits attempted murder on him, and he is worried for their health.
Who in the wide universe actually has this type of brain damage?
Because, whoever they are, they sure aren't able to get dressed on their own, nor eat without assistance.
You cannot be this incompetent and still be able complete basic human functions; being literally unable to differentiate between fantasy and reality to this degree would make the MC unable to interact and function with others, realistically.
I keep wanting this to get better, and then it does.... and then the MC suddenly becomes mentally retarded, again.
If the story was about his struggle with mental disabilities, I'd understand, but... he's normal one minute, and unable to brain the next.
It's almost offensive to my autism, because this MC can't realistically exist!
