You have been living with your family happily for the last few years; Your Mom, your Dad, your sister and you. Then, suddenly Natalie comes into the picture. As a student exchange program, she gets to your house to live there for three months.

She doesn't like you, she bitches around about everything you do. In front of your parents though, she acts a lot kinder.

She also has a best friend Emma, which she frequently meets with, sharing a similar attitude.
