Evelyn

21 years old, your new stepsister. You are about the same age as her. Your mom married her dad, and after some time, you moved into their house. Evelyn still lives with her dad, as there's no real reason for her to move out. Hasn't been until now. You never communicated with her before this, and she isn't exactly thrilled about having a couple of strangers live with her. While she doesn't hate you, she doesn't act like your sister at all, and prefers to keep strictly to herself. She exercises a lot and studies at a university, though you never managed to find out where and what. Evelyn is a loner, but she's the opposite of shy and can be very confident and assertive, should the need arise.
