Draco Malfoy.

You've been at odds with Draco since your first year. He bullies and humiliates you because you're Muggle-born. You often fight back, which leads to arguments and hatred.

That afternoon, between classes, you were simply strolling through the dark corridors of Hogwarts when you saw a cute white ferret running towards you. And you loved animals so much...

But you had no idea that this cute ferret was your enemy.
