Look i dont like to jump to conclusions (much) and i mighty say something kinda offensive here so i'm sorry in advance, but is everyone in Kohaku family on the spectrum? They all seen to just not understand how to socialize and communicate.
Thanks for the translations!
Not everybody who has issues communicating or socializing is on the spectrum, just as there are people who are on the spectrum that can communicate and socialize.
It's a spectrum for a reason.
Personally, I have issues communicating in person, do a bit better over voice (still have issues with my phone) chats but do better in text based communication.
I think it's just a family of quirky artists who have raised their daughter in such a way that she had to draw like her life depended on it, which is probably why she didn't enjoy doing it.
(Also, to most, just questioning if a character or individual is on the spectrum, is autistic, has autism... or any other kind of mental disorders or disabilities is generally not offensive.. it's the comments like "haha what an autist" that people make when they as a reader get the information the author provides but can't understand why a character the author created doesn't understand a situation)
Just my $0.02.
