Hermione keeps catching on fire whenever she's close to Malfoy. Literally.
It's only just a crush, it'll go away. That's what she told herself every time she ended up staring at him. She tried to not entertain those dangerous thoughts. She was Hermione Granger, after all, if she put her mind into it, she could rationalize anything. Hermione's just trying to come closer and Draco feels the urge to run away.
She is trying to get closer to him. He's trying to run away from her. Should she give up. Should he give in.
