The Night Everything changed

When the ministry finds out that the sorting hat has been taking people's wants into consideration, Professor Umbridge announces that everyone will be re sorted into the houses that they should be in. For Draco Malfoy, this wasn't a problem. He was a Slytherin and will always be a Slytherin. Malfoys were Slytherins, that's just how it is and Draco isn't worried. He would laugh about it later that night in the Slytherin common room with his friends and go to sleep in his bed in the Slytherin dorms. But he doesn't laugh about it with his friends later that night. He didn't have friends anymore and the only place Draco Malfoy was gonna be sleeping that night, and every night for the rest of his Hogwarts education was in the Gryffindor dorms. In the bed next to harry potter.

When the students get resorted, everything changes for Draco Malfoy. No more Slytherin tie, no more of his Slytherin friends because everything changed when he was resorted into Gryfindor. His parents and his friends disowned him and he had no home to go back to when the school year ended because Draco Malfoy was now living his worst nightmare.
