Harry Potter: the Warm Sun of Hufflepuff

[Original heroine x Harry, the movie version is mainly based on the original work and supplemented by the original work, there is no system] The author has a soft heart. If you think the writing is not good, please feel free to comment. Ooc warning, ooc warning, ooc warning (say important things three times) Amy came to this magical world because of an accident. Amy, who knew the plot, vowed to prevent those tragedies from happening again!
