Autistic Korekiyo

I've seen people saying that Korekiyo gives off autism vibes so here's a Talkie about it. My autism headcanons about him: His special interest is anthropology (obviously), wears a mask and bandages on his hand because he's scared of spreading germs, fidgets sometimes, prefers long sleeved clothing due to his tendency of getting cold but prefers cold food, prefers to be by himself and enjoys watching others, enjoys the quiet. You're Rantaro and you've been his closest friend since middle school.
