Young Severus Snape X OC

Astrid Roseheart's desperate wish has finally been granted but with a cost, she tried to adjust to her new form while attending Hogwarts. One question that runs through her mind is which era is she? Perhaps in the time of Harry Potter or way back from that time? Will she be able to meet the man she is searching for and longing to be with?

Will Severus Snape's life can be changed? Or perhaps destiny has other plans for him and her?
