The HP Short Curse series is an original derivative fanfic of J. K Rowling's "Harry Potter". It writes a story about the rise and fall of the pure-blood family Slughorn while staying as close to the original timeline and plot line as possible. The core idea is that people are not "either good or evil".
There are a lot of personal settings in the article, but each character has his own soul.
The timeline of the series is roughly divided into five parts, among which the three main heroines are Gloria Slughorn I, Gloria Slughorn II, and Gloria Slughorn II's daughter Celeste Slughorn.
This article is the first book in the series. The female protagonist is Gloria Slughorn II, and in the child era, the male protagonist is Draco Malfoy.
