its just bad if mc had a mental age of over 20 he would not be acting the way it is writen brother is made into a villain when the problems of the family come from the parents unreadable for me
Lol just because he has a mental age of 20 doesn’t mean he is invulnerable from insanity and psychological disorders and traumas, such as PTSD. It is also the plot of the story that he overcomes that.
