Part One of Three
In all of his thousands of years, Castiel had never truly loved someone. Dean used to say it was because his standards were too high, but nonetheless, he lived a lonely existence. Until he met Dean Winchester. Dean was heroic, self sacrificing, a hilarious drunk, a protector of his little brother, and very badass, all traits that the angel simply couldn't resist. He knew he wouldn't be able to live without the human. So Cas made a decision that was too obvious to deny: he wanted to marry Dean. He knew that Dean wasn't an old fashioned man, so he couldn't get him a ring. He had to think really hard about it. "what if I get him a new demonslayer knife?" he thought, "no, he and Sam would only argue over whose was best...A vintage Metallica vinyl? Hm. No. Too plain." Castiel was in turmoil for days, weeks, months, trying to think of the perfect proposal All the while, Dean was clueless that any wedding bells were ringing in Castiel's ears. One night, while halfway through drinking a New York liquor store, ignoring the gaping mouth of the owner, Castiel was struck with the best idea he'd ever had, the perfect proposal for his perfect boyfriend. He immediately huffed, "thanks." towards the barkeep, wiped the poor mortal's memory, and vanished.
