I very much enjoyed reading this short story. It's so rare that we gain insight into Draco's feelings, i.e. what's beneath the surface of his overt bullying behavior. This story was, overall, very well constructed and written. There was repetition of Draco's verbal expressions about betraying friends and family; however, this is easily remedied should you ever wish to, perhaps, find different ways of saying the same thing.
The ease with which I could imagine the scenario unfolding in my mind as I read the story impressed me, as I consider myself to be a very visual person. This added depth to the reading experience because the story and emotions came to life for me.
Writing a short story is, in many ways, more challenging than a chaptered series, because it must encompass a beginning, middle and ending within a constrained word count. The author must tell the story quickly and concisely - and tell it well. You've certainly done that!
BTW, if you do ever edit the story, I'd suggest you remove the words "The End", as it isn't necessary to tell the reader they've reached the conclusion of the story!
