Aoba is definitely not above teasing, but tends to lead with it more than anything: the moment people start teasing back, it's hard to reply in kind. Not that he minds being on the receiving end at all... Even the best of friends should be able to tease each other, right? Then obviously it should be fine to take it from virtual strangers, too. It's pretty easy to tell the difference between teasing and actual insulting, after all.

"We exist just fine. Or at least I do. I don't know that I believe you exist, with all the door-eating in your sleep." Huff, huff. He feels a little too defeated to forego some kind of defense altogether.

Still... "Nice to meet you, too, Yunlan." He's honestly tempted to call the man 'that asshole' now, but he just doesn't have it in him to be so deliberately rude to a nice person. "I'm Aoba - Seragaki Aoba, but just Aoba is fine."
