Harry Potter has a cousin? !
The Dursleys have a daughter? !
That annoying Dudley guy has a sister? !
Will Harry's childhood be much easier? Will the Dursleys dote on their daughter? Will Dudley become a girl-controller? Does your cousin know the plot? Is she a super invincible Mary Sue?
Sorry, if you want to see the above plots, there are none in this article.
The heroine is not a time traveler, does not know the plot, is relatively passive, has little effect on the plot in the early stage, and cannot save any main characters. The eldest child of the Dursley family is still Dudley. Even if the heroine enters the magical world, she will not have the halo of the protagonist. After all, Harry is the only protagonist of the original work. The ending of this article is a tragedy. I'm sorry if you can't accept BE, but maybe this article is not very suitable for you.
This fanfic is just an idea from the author: If Dudley had a sister and was a wizard, would the story of Harry Potter change?
But in fact, the author just wanted to write about the joys, sorrows, joys, experiences and feelings of an ordinary but unique little girl who followed Harry into the magical world. This article is a look at the magical world from Darlene Dursley's perspective. It must be wonderful, but also strange.
In general, this is probably a story about a little girl who is slightly socially afraid, introverted, and likes to complain silently in her heart, and gradually grows up.
PS: This article's CP Fred Weasley is a warning for emotional drama.
Purpose: This article focuses on describing the stories of the little characters in the original work who are described in only a few sentences. What I want to illustrate is that the little characters also have their own power, and it is they who use their own strength and spirit to fight against Voldemort.
