"Upside-down"

A girl from NYC just found out that she a wizard and she needs to attend Hogwarts to learn how to control her overflowing power and so her world is turned upside-down in. She's new and confused but she makes friend quite quickly and her adventures begin. She's a very patient person but this one is just keeps annoying her to the next level so she doesn't back down either and so the rivaly begins. Will it end with a fierce love or a life time rivaly?
