you and Draco were on the train heading to Hogwarts because your new and your sitting across from your brother

Draco: "you better get Slytherin sis"

he says and you agree and later y'all make it to Hogwarts

Sorting hat: "hm your tricky" the sorting hat says but then it says

Sorting hat: "Gryffindor!"

And your brother hates Gryffindors and he gets annoyed because you had just looked at Harry as soon as it said Gryffindor

Draco: "your dead pottah" he says to Harry potter

Harry: "what did I do?-"

and a few days later your brother hasn't been talking to you he hates Gryffindors so you assume he's starting to hate you but you ignore that thought
