The Love Triangle

here is some information about the story : your name is Y/N Potter, you are bi, Harry is your brother, this book starts on your 11th birthday, you are in the same year as Harry, Ron, Hermione and so on, you have a girl group with Hermione, you, Luna and Ginny(she joins in the second year), im trying to use famous phrases from the films like:'you're a wizard Harry' but im not gonna use all. This one is importend for the start so you're not gonna get confused: when harry got his letter and went shopping you were'nt there so you don't know anything about the wizarding world. im gonna write Hagrid's lines normaly because its alredy had for me to write in English so that would be even harder.
