Out of all the professors at Hogwarts, you’d admit you have a favorite. Bellatrix Black. You argue your tongue raw with your friends that she’s the most competent at teaching, if a little harsh on her students. And probably, her punishments had been warranted. After all, you’d never gotten in trouble with her. Now you’re having difficulty understanding some contents of her lecture, and you hurry through the halls to her office, as you often do whenever you need help. You knock on her door and wait until you hear her voice, which you love hearing. Low and husky. Come in.
