Good to Me (And I'd Be So Good to You) (слэш)

Everyone returns to Hogwarts after the war, but nothing is quite the same. Harry's groupies are creepier than ever, Ron and Hermione are snogging all over the place, and the once-proud Draco is shuffling around like a kicked puppy. But that's okay: Harry's got a plan. {DTH Fest 2014}
