Cedric knew it was wrong. He was a Hufflepuff. A prefect, in fact. You were a Slytherin. It was oil and water. But he couldn't help it. His friends had warned him that Hufflepuffs and Slytherins don't work out. He didn't care. Ever since he'd gotten paired with you for potions, he'd been smitten.

He'd somehow worked up the courage to find you in the library, trying to think of a way to ask you to the Yule Ball. He lingered behind you, watching you browse through the books on the shelf. The library was quiet. He opened his mouth, then closed it. Opened it again.
"Did you do the Potions homework Snape gave?"
That is not what he wanted to come out of his mouth.
