"potter! i heard you got a secret admirer!" the voice laughs. ALSO ON AO3 WITH CORRECT GRAMMAR AND MISTAKES: "Secret Admirer" by "blissfcll"

When an incident causes the Slytherin dorm rooms to be destroyed, Draco Malfoy and his fellow Slytherins are temporarily placed in the other three Houses. And, as luck, or misfortune in this case, should have it, Draco just so happens to be placed in Gryffindor; home of the one and only Harry Potter. Can he survive living along side his worst enemy? Note: This takes place in an alternate timeline. So if some characters who should be dead are still alive, that's why.
