I Walked into the Book I Wrote

I wrote a fantasy novel with a huge number of words. The male protagonist in the book is Long Aotian. The heroine in the book is Mary Sue. The male supporting actor in the book is the most popular. The female protagonist in the book is a black yandere. The villain in the book is beautiful, strong and miserable. The passerby in the book... Okay, I will dress up as the passerby in the book... Then I was hijacked by the [Subversion of Plot] system, which wanted me to be the protagonist and defy the sky, the earth, and the air... As an author, it's so difficult for me! The text is in third person, please don't pay attention to the nonsense in the introduction!
