Cedric Diggory asked you to go with him on Yull Ball. You weren't really surprised, bc all boys in Hogwarts were head over heels for you. You said yes.

You go back to dormitory and your roomate, Harry Potter, start acting so jealous

"Why did you said yes?!"

"You're not my boyfriend. You can't controle my life. You can't even when your my boyfriend."

You said, coming closer to him. Harry was sweating when you come closer. You angrily punch his chest, yelling at him.
