After Traveling Through the Book with My Best Friend, I Rewrote the Ending of Cannon Fodder

My best friend and I both assumed the role of cannon fodder in a Mary Sue heartthrob novel, and it took three years for us to finally wake up. She is Bai Yueguang's stand-in, and was eventually pulled in to protect the heroine from disaster. I was an assistant to one of the male protagonists. I was fired for being disrespectful to the female protagonist and ended up living on the street with a broken leg. When Bai Yueguan returns to China and the plot is about to begin, we finally pick up.
