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.
