Olivia once thought she was an insignificant orphan in the Muggle world. When he was eleven years old, he received the admission notice to Hogwarts. The hope that was briefly ignited was completely extinguished by the fear and disgust of his adoptive parents, and he was ruthlessly abandoned.
When she entered Gryffindor with scars on her face, what she encountered was not the warm college life, but the malicious teasing of the predators and the subtle but more lethal mental isolation and belittling of Lily Evans.
Suffering so much, she finally chose to drop out of school, and her life fell to a cold bottom.
The twist of fate came in desperation.
Olivia was found by the prominent Thorne family. She was the long-lost daughter of the president of the International Federation of Magic and a Muggle government diplomat. The family's guilt and reparation poured in.
Under the careful arrangement of Horace Slughorn, she transferred to Slytherin and tried to reinvent herself in a new environment. In the deep corridors of the Snake Yard, she met the equally lonely and talented Severus Snape.
He initially only had a cold look at this "airborne" pure-blood young lady. However, Olivia's indelible tenacity, keen intuition for potions, and the deeply buried loneliness and trauma that resonated with him were like a slow-acting potion, quietly eroding his frozen inner defenses.
