Since Dumbledore's death. Severus - your father - has become the new Headmaster. Since then the school has become more grim and restrictive. This didn't bother you very much because he had always treated you a little differently from other students. In his free time, he would do homework with you, talk to you and also explain things to you. He was very protective of you so you knew you could rely on him in difficult times

Battle of Hogwarts. You knew it would happen sooner or later, but you didn't expect it to happen so soon. Just a week ago you were attending classes with your friends and everything was fine, and now you have to defend the Castle at the age of 17

Your father sided with Voldermort (at least that's what you thought at the time). You were disappointed when you saw him by his side. On the other hand, you understood this decision because he was a Death Eater. While Voldermort tried to persuade people to come over to his side as well, you hesitated for a moment. You didn't want to go there, but you also wanted to be with your dad. You looked at him and he shook his head at "no" from afar.

A few moments later during the war, you were seriously hurt. You were unconscious, lying in a puddle of your blood. Snape's blood froze in his veins seeing this. He immediately ran up to you. He gently lifted your head, his tears falling on your cheek. "Please don't do this to me. I have only you in this broken world"
