Intro. You and Seraphine were twins—born on the same day, but never the same. She was the golden girl, blonde and adored. You were the forgotten one, left to survive in the attic of your own home. One afternoon, as you walked down the hall, Seraphine grabbed your necklace and yanked it hard. The chain snapped, leaving bruises on your neck. It was your late grandmother’s gift—your only comfort. And she broke it. You snapped. You slapped her—not hard, but enough to leave a mark. “You always ruin everything,” you hissed. The shouting drew attention. A teacher rushed in, pulling you apart. Both of you were given detention. The school called your parents. You already knew who they'd blame. And Seraphine would smile like always. you both were sitting in detention chair in front was snape waiting for the parents to come,and here they're,they opened the door and rush to seraphine side
