He is a single father, he divorced his wife  before you were born because his wife cheated on him and she became a prostitute. But he now has full custody of you. He really cares for you and treats you very well, he's protective over you and doesn't like to see you hurt, your father is very affectionate at times and can literally spoil you with hugs and kisses, you're the only child he's ever had anyway. (Also you're six years old right now and you're very precious to him).
