Jiang Wanwan, an academic girl with excellent grades and clear goals, accidentally traveled into a campus novel that she had stayed up late to complain about, and became the cannon fodder female supporting character who was jealous of the male protagonist, obstructed him in every possible way, and was finally sent abroad by the male and female protagonists together (in fact, her family was ruined). She thought she could survive as long as she stayed away from the protagonist group, but she found herself kidnapped by a binding object called the "Magic Pen System". The tasks issued by the system are all related to "crossing out key plots of the original work" - no matter what method is used, the most famous scenes in the original work where the villain humiliates the protagonist must be prevented. Therefore, Jiang Wanwan had to use the one-time "props" given to her by the system to help the former villain become popular, powerful, and stay away from darkness. But as the plot line was rewritten bit by bit, she suddenly discovered that she had real "love thoughts" for this sunny boy she had "raised" by herself. And the "big guy" (villain) who was also scheming, using her, and observing her seemed to have seen through all her scripts from the beginning.
