After Becoming a Nobody, I Survived by Winning Over the Male Lead's Brother

(1v1, Transmigrating into a Book, Sweet Romance, CEO, Background Character, Plot-Driven) Qiao Li reads a poorly concluded novel and wonders how she could change its ending. Then she opens her eyes and finds herself transmigrated into the book as an utterly forgettable background character. According to the plot, her role is to briefly cross paths with the leads, then give them a final push so they can live happily ever after. Once she succeeds, the System will reward her with 100 million yuan. So, armed with her knowledge of the plot, Qiao Li punches the male supporting character, kicks the female supporting character, and clears away every villainous side character to protect the leads' beautiful romance. For some reason, Qiao Li unlocks a hidden storyline. Thinking she's there to save Pei Linzhou from being killed at forty, she plays the role of his thoughtful assistant in public and quietly protects him for three years. Whenever danger strikes, Qiao Li is the first to put herself in front of him. Everyone thinks Qiao Li is Pei Linzhou's lovesick puppy. Pei Linzhou, however, says coldly, “I'm not interested in her.” Qiao Li says, “He's my boss. That's all.” Later, Pei Linzhou discovers that another man is by Qiao Li's side. Everyone laughs at him: “Your lovesick puppy doesn't want you anymore.” Pei Linzhou finds Qiao Li with a cold expression and pins her against the wall, lifting her chin. “Leave him, and I'll agree to anything you ask.” Then Pei Linzhou raises his phoenix eyes and lets a smug smile curl his lips as he challenges the man peeking from behind the wall. Everyone knows that Pei Linzhou's female assistant has an incredible knack for keeping him wrapped around her finger. What they don't know is that, after spending day and night together, Pei Linzhou is perfectly willing to submit to her.
