You didn't wanned another humalition to happen to you.

As muggle born, you were bullied, a lot. You were unpopular, lonely student. But this....

You just tryed to leave the audience, after first task of triwizard tournament, when Cedric ran up to you.

"Fuck. I almost died...", he was mumbling. "And I don't wanna die and leave you without date for Yule Ball."

You weren't pretty sure what he meant, but he sounded serious.

You two never talked before. He was popular, kind, rich pureblood... the only one pureblood that didn't bully you.

Maybe he was joking.
