Defeat of Man by Zaria. It's a Hetalia doujin though...
Umm....every single one from here, i guess? http://www.mangago.me/home/mangalist/25771/
BUT, Ze will always be my No.1, period!
"Katekyo!" by Moegi Yuu is my absolute favorite yaoi manga. I really love the art style and the tory. It's both very cute and sexy at the same time.
