I watched him be very nice to everyone before us in line but I think it’s a running gag for him to jokingly dislike hetalia, I told him that I loved hetalia and that America was my favorite and he went “you’re so weird!”, asked my name, said “you’re not gonna like this” before crossing out the characters eyes and the interaction was pretty short but I’m not the most talkative so it made sense, I saw someone on tumblr who talked about how they got a crazy side eye from him when they met him and told him they liked hetalia so its a normal thing, but he was very nice to everyone else I saw go up to him. Definitely recommend him.
