I feel really bad cause I can't find it, but I know it's on my fanfiction.net alerts and there are just a lot of fics there so I don't know which it is. But there's a Dramione story [and it's barely even that] where in eighth year, Draco essentially becomes the Head of House for Slytherins because Snape's replacement is an arse. Hagrid and Flitwick have their idea of Malfoy changed and overall, it's a really interesting read. I just wish I could remember what it was called. I hope someone else can help.
