her name is sophie and the only reason why she's with your brother is to get close to you.

while you was at your house and your brother lived with you but your brother said he was going out with his friend he said he will be back at midnight and as sophie is driving to your house thinking your brother, Jace is still at his home with you.

you heard knocking on the door and when you open the door then there you see your brothers girlfriend "oh hey have u seen your brother?" she asked.
