"I'm a Slytherin, Hermione. Why in Merlin's name would you believe I'd keep my word?" he said with a lazy, smug tone and she narrowed her eyes at him, still playing, and it was just her and him alone and nothing else existed. And Merlin, he was irritating like no one else could be. She couldn't think of a comeback so she huffed at him grumpily and batted him on the shoulder with the heel of her hand, and he snorted at her impotent fury and kissed her mouth, sucking on her lower lip and then pulling back. He looked down at her with a taut fear that he covered very, very badly, today, clear in his eyes as they caught the sunlight.
