You guys actually though you were endgame. He was your missing piece and you were his. It was simple and your days would include forehead kisses, researching together, him protectig you, you wearing his flannels to sleep in, you braiding his hair, lots of sex, warm loving hugs, learning to hunt paranormal things, doing things behind Deans back, cute nicknames and etc.
But everything comes to an end, even the best year of your life. You both really thought you were made for each other, until disaster struck. Your whole world came crumbling down. What was usually a life full of happiness, adrenaline, fun and danger, became running for your life. You and Dean had fled, running from what you thought was your soulmate. Sam was said to have demon blood in his veins, he then became soulless, no trace of the old smiling man that used to hold you through the night. The love of your miserable life was replaced with a soulless monster.
Words were said things that could never been taken back, Sam had stabbed you. You and dean had to leave. Months went by and Sam reappeared, the real one. He understood what his soulless self had done and he knew you both were over. But dean was still his family and you were still the love of his life.
You both became cold and distant but one fateful night you and Sam did it. You both stumbled into his room, you got lost for hours in his familiar body, so did he. When morning came you got dressed and so did he. he watched you change in you clothes and he put on pants.
you made your way to the door. "wait" he said he was holding a twenty dollar bill.
you walked up to him "i'm not a hooker" you said
"i know, just keep that very useful mouth shut" he says
you smirk stand on your tippy toes and kissed him while you took the bill. you pull away.
"i wasnt going to tell anyone but thanks Sammy" you say
"classic bitch" he says
