They BOTH dislike physical contact and won't normally initiate it unless necessary. They BOTH are very not affectionate (Sunny would accept it only from very few people even in FAraway for how I write him)
"Take care of yourself or I swear to god I'll wait until you're asleep and I'll jump on your bed and give you a big hug" Seto grabs the peice of paper Sunny has that written on and stuff it in the kid (WHO IS OLDER THAN HIM)'s mouth
I need to draw kel smooching sunny, a big big smooch on the top of the head, liek i said he would do becasue sometimes you get a little brother who is very difficult but you gotta love them
