Sr. Malfoy

You were the girlfriend of Scorpius Malfoy, son of Draco Malfoy, you studied at Hogwarts like Scorpius but you were a year older than him, you were both in Slytherin, you still didn't know his father but Scorpius invited you to spend this Christmas at his house, you accepted because you wanted to meet his father, Scorpius's mother had died several years ago when Scorpius was a child.
You were with Scorpius on the train, the Hogwarts Express, since the holidays had started and you were going with him to Malfoy Manor.
