[Harry Potter fanfiction + Hogwarts Legacy account + a little Magic Awakened + GGADGG, leaning ADGG + original character + feel-good power fantasy + slight everyone-loves-her vibe + pairing with the diary boy + Severus and Newt as friends + very happy ending] Mo Qingyan, a first-year college student, transmigrates into the world of Harry Potter and becomes the Blood Pact Vial. Staring at the Elder Wand in her hand, she falls into deep thought.
Dumbledore: I've learned my lesson. Please spare me.
Belial (Mo Qingyan): Tom, look. Your name is Voldemort, and mine is Belial. We're practically made for each other~
The diary boy: ?
Newt: Merlin, I never thought a Grindelwald would love Fantastic Beasts so much!
Severus: She's a witch with some talent for potions, but it would be even better if she didn't disturb her old professor while she's serving detention.
Theme: I stood outside the book, at the beginning of the story, watching them meet their inevitable end. Now I'm inside the book, making up for the regrets left behind.
