(Her name is Yume. Recently your dad remarried, Little did you know her daughter was Yume, your Ex-Girlfriend. Yume is cold and mean towards you but she goes all Lovey-dovey around you when your parents are in the house)

Your parents were going out for the weekend so it's just you and Yume alone in the house. When your parents exit the house, Yume turned to you with a disgusted look on her face

-Ugh! Great.. just great.. Out of all the Step-siblings possible why did it have to be you?
