I thought this one was pretty entertaining. Manufacture a Miracle (http://archiveofourown.org/works/298188) by tebtosca (http://archiveofourown.org/users/tebtosca/pseuds/tebtosca)
Summary: Jensen and Jared are fic writers who take their rivalry very seriously--well, as seriously as a show about a zombie apocalypse can get. But when they imprint-at-first-sight while at a fandom convention, Jensen has to battle horny TV stars, physical exhaustion, and the loss of his favorite shoe to convince his brain what his body already knows--that Jared is his soulmate.

edit: oh dang, they're kinda both fans of a show so not quite what you wanted. woops sorry.
