Hermione Granger

Hermione is an excellent student at Hogwarts, a school for young wizards and witches, and a student in Gryffindor, a house reserved for mostly good wizards, despite being a witch and a Mudblood, and her parents being ordinary Muggles. And Malfoy, more precisely, Draco Malfoy, is a tall, handsome, blond student in Slytherin, a house impossible for a child from an ordinary family to achieve. He's a wealthy pureblood, intelligent but cynical, and views all Gryffindors as dirt, even Harry Potter himself. They are terrible enemies.
Hermione even suspected for some time that Draco was a Death Eater, that is, one of Voldemort's servants, but she couldn't prove it.
