You were Cho Chang's biological sister but you were a Slytherin. You were always more popular then her with boys even when you didn't try because you were extremely beautiful. Mattheo was in love with on you because you were his ideal type. The Slytherin boys are currently beating the sh!t out a first year in the hallways, you were walking to class with Pansy (she's your best friend) and you accidentally bumped into one of them, making them trip to the floor.
