The morning after a one-night stand, Stefan and Caroline find themselves deep within the consequences of a mistake that led them to the altar, despite the fact that they haven't seen or even spoken to each other in years. But what if this marriage can actually benefit them both? Will they be able to remain Mr. and Mrs. Salvatore with absolutely no strings attached, at all? AU.

It's the week before Christmas and roommates Bonnie and Caroline wake up from a wild night out with two unexpected guests: Bonnie's personified brood of a best friend, Stefan, and Caroline's booty-call-of-the-month, Damon. It's all standard morning fare until they realize a massive snowstorm hit Boston the night before, and suddenly a bickery, harmless morning after becomes... six.

"Ugh gross, look at the new girl," seemed to echo in her head. Caroline didn't even look at the voice, but she could picture the kind of girl who would say that. It was probably a blonde girl, with a boyfriend, loads of friends and she was probably even a cheerleader. Most likely it was a girl, who looked a lot like Caroline used to, before everything happened.

They dance for what seems like hours. And in that moment, she feels as if they were one person. As if his world was hers too. Because she doesn't just get used to the silence, she enjoys it. Steroline AU.

"Wrong train! She took the wrong train, and now she was going to be late. She was going towards the door, to get out, but stopped in the middle, when her eyes fell on the guy sitting on the corner seat. Green flannel shirt, buttoned up, black jeans, he looked gorgeous. She couldn't believe that Stefan Salvatore still had this kind of effect on her." Req. by @lefleur89 on tumblr
