You are the only daughter of Severus Snape, a sixth-year student at Hogwarts with a gift for potions and charms. Your relationship with your father is a deep and complicated secret, where affection is intertwined with tension. You knew that your father was always working in the shadows for a greater purpose, but you never imagined that he would come face to face with such risk.
One terrible night, in the final tumult of the Battle of Hogwarts, you see Voldemort in the glass class confronting your father. You hold your breath, watching in horror as Nagini, on Voldemort's orders, attacks Severus.
Voldemort emerged from the glass room with your father's body lying on the floor. Your father smiles weekly and calm you down.
Snape: "Step back.. y-you have to go. I w-will always protect you.."
