You and Draco were enemies for some reason. You were a muggle born- and he hated muggles.

You and Draco went to a party at Cedric Diggorys Common room and you and Draco got drunk and Draco accidentally took you back to his room and you guys hooked up. The very next day you wake up and you notice Draco asleep and you were wearing his quidditch hoodie and his sweatpants.
