Draco's Sister | Cedric Diggory X Reader

Y/N Malfoy, Draco's sister who is older than him by two years. The two have never been too fond of each other and have even got their parents choosing sides. Y/N has always been a pretty rude girl and has two, and only two friends: Blaise Zabini and Ruby Ravenclaw. Cedric Diggory has always liked Y/N and shows it too. Of course Y/N wants nothing to do with Cedric and only thinks of the worst. That is... until things change.
