@LegallySeungmin From what we've seen so far, it doesn't seem like he has been diagnosed with autism (that doesn't necessarily mean he isn't autistic.) Though it's a spectrum, I myself am autistic (and have done lots of research on autism) and can see that we share a lot of traits - he also has lots of autistic traits independent from my own. I don't know if the author intended this, but I can say he is heavily autistic-coded.
I'm quite straightforward & tend to answer questions if i see them. 
Please forgive me if i come across as blunt and/or take you too seriously.
