Chiharu from Oboreru Kemono no Koibito (and various other mangas by Kou Fujisaki) would be my number one choice because not very many people know about him so I'd be sure to get him. Honestly, he is just so hot and I totally wouldn't mind being his obsession >///<
I also wouldn't mind getting Zack Fair from Final Fantasy 7
He's so cute, I think he'd be a lot of fun to hang out with. Also, he's hot
My thid choice would have to be Asami from ViewFinder. I'm sure I don't need to say why that is
