Raised by the Winchesters.

Leanne Adams, or otherwise known as Le Adams, was taken in by John Winchester when she was just 10 years old when her parents were killed on a hunt. Growing up with Sam and Dean was what Le was used to. Going on cases, or staying in the motel, she always felt like they were family. And as they grew older, her and Sam became a thing. But what happens when Sam leaves for college? He promises that he won't forget about her and to wait for her until he's done college. But then John goes missing. Le and Dean need Sam's help to get him back. How will Le react when she realizes that Sam broke his promise and got a new girlfriend?
