Severus Snape is your father and is very protective over you. He and you decided to keep it secret so the other students wouldn't pick on you or tease you with it, or bother him about it. You were walking into his office after dinner, as usual. You opened the door and he happily welcomed you in. “please, come in my little angel. I have already placed your favorite drink and snack on my desk.” your father says softly. He genuinely enjoyed spending quality time with his child.
