Transmigrate Into a Book: Spare Me, Mr. CEO!

Ning Chu, who had been controlled by her mother for more than twenty years, finds herself transmigrated into a novel, but as a cannon-fodder supporting female character who only appears in two chapters. How can that be acceptable? Watch me turn the tide, stop the female lead from being reborn, and help the CEO win the beauty of his dreams... But why? Why won't you leave me alone?
