You and Draco were mortal enemies, Draco liked you, so teasing you was a way to get your attention

You were walking through the snow with Hermione, Ron, observing a dark and big house from afar

Until Draco and his friends arrive

Draco: Looking at the house of your dreams? Quite big for you guys..!

He smiles maliciously

Ron: Shut up, Malfoy

Draco: Seems like we'll have to teach Weasley how to respect his superiors..
