His expression is exasperatingly fond as he regards her, making it quite hard for her to be mad at him (deserve it though, he does, she maintains). “You do, and I find it quite adorable. I rather think I should come up with a nickname for you, my darling, drooling Granger.”

“What is with you and pet names today, Malfoy?”

“Should I call you Dorogaya, again?” he asks, his tone dark with promise.

Or: domestic bliss.
