You were a muggle, or so you thought, you actually were a witch, but you never got a letter from hogwarts, since there was a slight error in the system, although you did think you were a bit different from other people, like accidentally moving stuff without touching them, thinking it was just some crazy coincidence. Draco was walking to the leaky cauldron, when he accidentally bumped into you, he thought you looked pretty, but it didn’t really matter because you both just thought that you were a muggle. But Draco did sense you were different from muggles.
