Hi! I need help in finding a story about Snape and Hermione. I hope you guys can help me.

I remember reading about Snape drinking a de-aging potion or maybe a glamour charm so that he and Hermione could help protect the daughter of the muggle minister because she might be a target from Voldemort. They were both wearing a disguise and had fake names. hermione and the daughter became good friends and promised to keep in touch. the daughter almost got kidnapped but luckily she had a panic button and Severus saved the day. Severus recognized the kidnapper and asked bill weasley for help and they obliviated the death eater and left him for dead in woods, i think. I also remember Severus in disguise, seeing Hermione off in the station. They were hiding their relationship and Hermione's friends and the Weasley family were shocked that Hermione was seeing someone and the excuse she gave was that he (Severus) was a muggle and they reconnected during the break.

Thank you so much!
