HP*******

In her previous life, Frila was a college student who had a "good luck" while trying to save a special child. In this life, she was born when the blood alliance between Grindelwald and Dumbledore broke down. What changes can she bring to their love? How can the system erase most people's regrets? What impact will she have when she comes to Slytherin? (Lightning protection: private design, fast progress, ordinary writing, no outline, write wherever you think, the protagonist has no cp, if you don't dismantle GGAD, Ariana will be resurrected, this is my first book, there may be many unreasonable things, I will try my best to correct it)
