summary: Jared was passionate about the work he did with the animal shelter. Between that and living with Sandy, life was satisfactory. Until the cold night that the filthy, homeless man hidden in an oversized hoodie was dumped at the shelter and Jared couldn't just turn him out. Even if the man roared and called himself 'Beast.' Because under the hood, Jared was sure he caught a glimpse of a prince in those green eyes.

antisocial!Jensen Sound Perception (http://rocketslash.livejournal.com/?skip=10) by rocketslash
summary: Jared’s life has never been complicated. He flies by the seat of his pants and makes the best of whatever he gets. Jensen lives a reclusive and controlled life. Not by choice, but borne out of necessity. When their worlds collide, it isn’t pretty but somehow they make it work. When Jensen’s past catches up with him, nothing is certain anymore. With the odds stacked against them, can they find their way back to one another or did they even know who each other really was to begin with?

this is more weird!misha, closed off/antisocial!jared, and weird circumstances. Drifting Through Doorways (http://archiveofourown.org/works/850488/chapters/1625888)
summary: One year ago, Jared lost his husband in an act of senseless violence. Stricken with grief, Jared has withdrawn from society and become reclusive, his only human interaction coming from his foster brother Chad, his florist friend Misha, and the occasional grocery store cashier – that is, when Chad can convince him to leave his apartment. If that wasn’t bad enough, now he’s being haunted by the ghost of his deceased husband, and Misha is the only one who seems to believe him – even if Misha's theories and superstitions make him a little, well, eccentric. Jensen, on the other hand, is finally free of his own unhealthy relationship. Too bad being one half of the couple known as Jen-Jen drove him completely bat-shit crazy. And he is, if the disembodied voice that only he can hear and strange dreams are any indication. After all, Jensen is ninety-nine percent sure he’s not a ghost (despite what the voice claims), and he’s never been married to anyone named Jared, either. This is a story about unlikely connections, second chances at love, and giving in and letting yourself be just a little bit crazy.

I had to split it off because of the word count limit. =(

Anyways I hope there are a few recs you'll enjoy here.

Edit: Here's another.
Jensen and Jared are both kind of mean and stuck up here. Bratty Little Bastards: Autumn (http://archiveofourown.org/works/914322/chapters/1772560)
summary: Jensen Ackles hates coming in second. Jared Padalecki can’t stand being overlooked. So when the same guy makes them look like chumps by taking over the varsity lacrosse team and ranking first in the junior class at the private, elite Eldridge Academy, overachieving computer genius Jensen and popular athlete Jared decide to put aside their differences. Kind of.

Talk Hard (http://sandymg.livejournal.com/31061.html) by sandymg
verse summary: Jared is a struggling grad student working a phone sex line to get by. Jensen is a recluse genius doing top-secret decryption for the Defense Department. Sometimes it's not about the words, but the silence between them.
