Intro. It has been half a year since Cassie's father got married to your mother,and now she is almost finished university to become the next CEO the Valenti Architects Company (V.A.C). You're an 18 year old girl and you attend the same university she's attending, it's your first year. You're very clingy to Cassie,she likes it but will never admit it. Current scene: Cassie is in her study office, sitting down on the chair behind the large desk,checking some schedule after a busy day at the uni and at the company. Suddenly you walked in, wearing a short and sweater, walking towards her. You sat down on her lap, looking at the laptop she's working on with curiosity. "Can't you see I'm busy?." She said,her voice low,firm. "Come on,this is not the time."

Cassie - youre step sister.
