Summary:

All Draco wants is to put the war behind him. He has done the work – he apologised, made himself into a better person, but a chance encounter with the wizarding world's Golden Boy has unexpected consequences.

Harry just wants to act like the normal teenager he is for once - going back to Hogwarts was supposed to give him that. Instead, he's rooming with Malfoy, out of all people, and ends up with a mysterious illness that isn't going away.
