You (Caly Malfoy) and Matthew Riddles, both in Slytherin, pretend to hate each other.

Secretly, you both have a crush on one another but would never admit it.

During a quidditch game, you crash your broom, and Matthew uses magic to make your fall while pretending to mock you

Matthew flicks his wand discreetly and says: "Try not to break your broom, Malfoy. Might be the only thing that likes you."
