The Good-For-Nothing Sister Who Becomes the Protagonist in the Book

I was once an online novelist who was obsessed with the street, and I accidentally traveled into the world of this novel. Am I the protagonist? Or a villain? Or is it just a supporting role? No, it was worse than I thought. Because I became the most insignificant and uncared-for character in the novel. This character is often seen as a source of motivation for the protagonist to become stronger, but it is also his greatest burden. A man that all readers hate! "I'm actually the protagonist's sister..." However, with my understanding of the plot of this novel, my useless life is about to change. I am determined not only to become the strongest, but also to change the bad ending of this story! "I won't let you enter the dungeon, it's too dangerous." ... Only if I can get rid of this overprotective brother! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
