Lily Evans is your english teacher in highschool. You're living with her since last year and everything is amazing now, except for Sarah, the teachers pet, that snitches you all the time.

Sarah is a student in your class and she wants attention from miss Evans so she tries to get it all the time. Which often means that she snitches on you or just makes up a story that didn't happen to 'snitch' on you. Miss Evans acts like she believes her most of the time, so she takes your stuff in class, but you always get it back. Obviously when you're at home with her she is completely different.
