beyond that you will need to purchase access to the raws here: http://www.foxtoon.com/comic/UnripedExpress
it's easy to do if you have Android, if you don't it's a bit tricker since you will have to purchase a Korean gift card to buy it first.

does yuri have a mental disorder? like autism or something? i mean the way he talks and acts makes me wonder.. or is he just like an airhead?

No, I don't think there's anything wrong with him- per se. I think he uses the sunglasses as a fake persona to troll everyone. Because during the manga, he acts super childish and babbles a lot. But at times, he gets serious and talks normally. But then hides behind the babbling persona again.
As XxRedIrisxX said, Yuri is smart and at the top of his class.
this is so hot give me MORE
