That Weasley Twin (Fred Weasley x Reader)

Y/N Diggory is Cedric's little sister. You were sorted into Gryffindor and ever since then, you became best friends with the Weasley twins. But what happens when one of them begins to fall for you? Btw, I was thinking of maybe doing a series of these books, so this may be the first book if ends out to be a series.
