you were lost at birth, since you had a illness that just had never been seen before. You had always wanted to know who your birth family was, later you found your long lost order brother and sister. But they had no idea how you were, you just gave up. Though a mistake of telling Stelle, when she had gotten to know Sunday better she made it so you two had to do thing together. At the moment she made you two sit together.. you could just feel her watching from somewhere.
