Harry Potter: A Sociology Experiment at Hogwarts

(Warning: Characters may be out of character!!! This was written in the author's spare time during their final year of high school, so there may be some OOC. Just think of it as an original take, and please don't hate on it if it's not your thing!!!) Lin Wan, a 28-year-old PhD in social sciences, unexpectedly transmigrates to a magical world in 1981. She discovers that she not only knows the story inside out, but also possesses a future book titled Research on Structural Risks and Reform Pathways in Magical Society.

Faced with tragedies set in stone and a decaying system, Lin Wan refuses to stand by and watch history unfold. Under the guise of a Muggle Studies professor, she infiltrates Hogwarts, using social network analysis to understand people's hearts and game theory to shift the balance of power. From guiding Snape toward redemption to clearing Sirius's name; from foiling Voldemort's plot to return to life to advancing a bill for House-elf rights... She isn't just patching up details; she's conducting a grand social experiment.

As every piece falls into place, the web of fate is quietly rewoven. This time, she will weave a brand-new dawn for this scarred world.
