A collection of one shots between you and the man who speaks in hands. Some will be long, some will be short, some will be happy, some will be angsty, some will be fluffy, some will be smutty. I will write for certain AU's, but don't be offended if I ask for an explanation of the AU you request, I don't know them all. I take requests.

Normal days in your huge...lonely....stupid house that was given to you by your mother and father. They gave you everything, but not out of love, just to get you out of the house. You were only 16, you could barely even drive. They bought you this house, bought you a car, a nice one, and gave you your uncles motor cycle. It was nice. Then they left this world. A ring, all you had left to remember your mother, and a necklace, all you had left of your father, and this stupid, stupid house. It was lonely. Now you were 18 and looking for a job. You had good grades, and everything you could ask for. Now all you needed was a special...someone.
