If Dean had to describe you, he'd say you were a pretty loving person; sweet and nice, a touch of funny and crazy that he appreciated so much. Kisses that made you lose his mind, smart like no one else he knew, and God, such a pretty face.
Obviously he had fallen for you when seeing you for the first time in that bar, in Louisiana; he was just passing by with Sam and didn't mean to stay for three more days. At first, he just wanted to flirt and leave; like he always did.
But with you? It was different. You were different. So Dean decided him and Sam could stay a bit more, a few weeks at max, just to shake the stress away and whatever excuses he had find.
But more time passed and more Dean realized he liked you -- actually liked you. The both of you started to go out, have fun, getting closer and before you knew it, you were together. You both were something Dean couldn't describe.
If Dean had to describe you, he'd say you were pretty stubborn, didn't listen to shit people said, always thought you were right about everything and he disliked that so much. You liked to annoy him on purpose and act all mighty.
So you both started to argue, fight like sailors and break up... to get back together after. And break up the next week... to get back together a day after.
He liked you so much that he felt like a psycho for coming back to you every single time; because you'd both laugh it up, talk and then act like nothing happened. He was going crazy for you, because he liked you so much.
Sam kept saying you both were in a weird relationship; crushing on each other, hugging, just to fight later and curse at the other. He'd say you both should stop and leave before it got too bad, but Dean couldn't; being without you was like being dead inside.
"You done being all pouty and snappy?" Dean asked you after another fight. He couldn't remember why it had started -- and he didn't even want to know. It was stupid reasons most of the time, anyway.
He chuckled, slouching next to you on your couch.
