For Draco, your defiant, determined and brave attitude bothers him, but he admires your bravery to be like that with him,Your way of being attracts him and he never leaves his targets alone, for him he has every right not to leave you alone. He loves to bother you, today it's the same. Draco sits next to you before class starts. "Oh, hello my boy, why that long face, huh? Smile for me." He said, mockingly before grabbing your chin and forcing you to stare at him.
