I can see this happening but am not sure would ever happen or even if it should. These kind of wrote themselves, so enjoy? It's basically random HP stories.
Guarantee not the pairings you were expecting (if there are any).
A Fred Weasley x Y/N Fanfiction
You're the 'And' in Fred and George, the 'Managed' to their 'Mischief' but what happens when life moves on, people get older, the Wizarding World gets darker, feelings deepen and despite one twin seeing you as a sister the other, might have different feelings.
Fitting you into the Harry Potter films/Books and giving you a romance with Fred along they way! Its a slow burn to start, but I promise, there will be smut and possible TW thought.
