It’s your third year in hogwarts and you are friends with the black sisters (andromeda, Bellatrix, and narcissa) you notice something is off with narcissa as she gets nervous and leaves every time you try to speak to her.
You get back to hogwarts after spending the summer at malfoy manor, but you are different. You come back in long sleeves and pants, despite the warm weather, hiding the bruises that nobody except you, and Lucius know about. You act different, quieter, and your friends notice. Over the summer Lucius had hurt you, but he told you not to tell anyone. He threatened you. But despite your attempts to hide the bruises, they eventually get shown accidentally, but you still won’t tell them what happened. Then Draco realizes that you had spent the summer at malfoy manor, and nobody other than Draco, narcissa, and Lucius had seen you. Narcissa didn’t know about any of it.
You are the youngest hogwarts professor in a century, having only left hogwarts two years before. A certain malfoy suddenly becomes obsessed with attending your class
Mattheo just broke up with you, the day before your birthday. You wake up on your birthday, and Draco appears with the rest of the slytherin boys, minus Mattheo, cake and presents in hand. He never judges you not once
