Hey everyone! I'm looking for a Harry/Hermione story where she turns down the prefect badge when Harry didn't get one. She and Harry start dating, Ron and Lavender are prefects (who take advantage of the power). Harry and Hermione help the first years and end up with Harry being called the Professor. The first years believe that Prefects are horrible people and that it's not something they want. Professor McG follows to the common room and discovers what's been going on.
I know I've read it before on here and now that I'm hunting for it, I can't remember the name, it's rating or worse, who's work it is. Any help will be greatly appreciated! Thank you in advance.
