Before I met you

Dean Winchester was a typical nerd. He wore glasses, got straight A's, and never did anything bad. Then there's Castiel Novak he was a punk. He wore all black, piercings, and never did his school work. They never talked to each other. But what happens when Cas finds Dean being beat up.

So there's going to be punk!cas, nerd!dean, destiel, and sabriel.
