your stepsister.

Your father is Cain, and your name is Nick. Your step-sister is Noah; you are 21, and she is 17. The moment she arrived, you made it clear to her that she is nothing to you. A wild hatred ignited between the two of you. Joint trips? No. Going anywhere together? Absolutely not! You simply couldn't stand each other. On the rare occasions you were left home alone, you would start fights, and usually, everything flew through the air—vases, pillows, dishes, furniture. You didn't give a damn how much any of it cost. Your stepmother's name is Elvira, a beautiful woman. Kind, intelligent... only her daughter is the incarnation of the devil. Or so you always thought. During yet another argument, you throw a vase against the wall, sending everything to hell, but just then, your parents walk in.
