[Hp]help I Am a Slytherin NPC

(Take the time to write, feel free to delete it, thank you for your understanding She discovered that she was a Slytherin NPC in the novels of the "Harry Potter" series, that is, she had no thoughts, no background story, and no plot, and she only served as the backdrop for Hogwarts every day. Whether it was pulling out Old Deng's beard, causing trouble in Snape's class, or not handing in Professor McGonagall's homework, no one cared about her! They can't remember it anyway, everything will be reshuffled according to the plot. She did whatever she wanted, even selling snacks to the hero with the lightning scar every time he had a fight with Slytherin! The results were discovered. The man he found had messy black hair, and a trace of anger flashed through his green eyes under the lenses. He took her arm and panted: "What's your name? Why are you doing this?" She pondered for a moment, put on a mean face, and responded with a standard answer: "Hey, isn't this the famous savior? What, the Academy Cup still doesn't satisfy you?" # Harry was very strange. At a certain point, he could always see a Slytherin student... Acting out of character? He asked Hermione, who said she had never seen this person before. So, the person who poured the potion of failure on Snape in class didn't exist? Could it be that he hated Snape's hallucination too much? He wants to find out the truth and prove that he is not crazy. As a result, he finally had the chance to stop her and ask her, and it turned out that she was no different from other Slytherins. Unwilling to give in, he went to intercept her again. She: "Hey, this is not famous——" He interrupted her knowingly: "Stop pretending, you always talk the same way!" Things to know about reading: Part of the inspiration came from an unexpected discovery one day. Concept: Everyone is the protagonist of life
