Sweetheart (Dean Winchester Lovestory)

This is my first fanfiction and englisch isn't my native language, so please be kind.

This story don't follow any of the spn plot, it just plays in the spn universe.

The story:
Mary has a rough past. She had to kill her parents, escaped the house of her ancestors and had to keep her head down ever since. Once Dean Winchester promised to be there whenever she needs him. But she was all alone. She learned that on the hard way. But what happens when he finds her again? Does he remember his broken promises?
