Eren is a 16 year old boy who has an abusive father and a mother who is way too forgiving about it. When Eren is casted away from his home, he wanders the streets, until a sleek black cat pulls up beside him a den changes his life. Can the man with black hair and gray eyes offer him the Safe Haven he's always dreamt about? Or will Eren fall into his own mind?

I don't own Attack on Titan, or characters, just the plot :)
