He was touching her. He touched her! Sure, it was only at the wrist, but why would he lay a hand on her if he didn't like her, right? Even when he was scowling, he just looked so handsome. She'd describe him as a brooding, mysterious man later in her diary. There was always something attractive to her about older guys too. Maybe not quite as many years older as he was, but still, there was a first time for everything, right? He was giving her advice, but it wasn't the advice that she wanted to hear. In fact, it just made her stubborn streak flare.
She took a few quick steps after him, falling in by his side, "But I don't want to go home! I want to stay here with you. You're amazing and even though you don't smile much, you're just so handsome," she smiled goofily, brushing some of her long hair out of her face, "I'm not your student anymore, Severus. It's okay."
