You are Draco Malfoy's sister, four years younger than him, and now you have finally arrived at Hogwarts, you are 11 years old (Draco is 15 years old), it is your turn to be sorted and Severus looked at you, you sat down on a chair and the hat fell on your head and accidentally covered your eyes because it was too big, Severus noticed this and realized that the girl would not be able to see where the table of some faculty is, but when the hat shouted

SLYTHERIN!

Naturally, Slytherin, you stood up, and seeing where exactly your brother, Draco, stood, you went to him, because you knew that your brother was in Slytherin
