The Foil Character in a Period Novel

[New Republic of China-era novel: The Female Side Character Is Determined to Serve Her Country, updating now] Right after taking the recruitment exam, Lin Hong learns that she is a cannon-fodder side character in a novel, a foil meant to highlight the female lead who transmigrated. The female lead is Cheng Xi, her neighbor, who is about to be sent to the countryside. Even though Lin Hong is already a factory worker while the female lead is going to the countryside, Lin Hong knows from reading the plot that... A little over two years later, the college entrance exam will resume. The female lead will get into university, while Lin Hong will still be working on the factory floor. Five years later, the female lead will marry the wealthy male lead after he is exonerated, while Lin Hong will still be working on the factory floor. Ten years later, the female lead will succeed as an entrepreneur, while Lin Hong won’t even be able to keep working on the factory floor. She’ll be laid off, go to the Special Economic Zone to look for work, and apply to the female lead’s factory! Lin Hong, now aware of the plot: Isn’t a transmigrator’s golden finger knowing future trends and who the male lead is? Now that I know what’s coming too, I’ll be the foil who highlights her by doing the opposite, and makes her jealous! Warnings: The male and female leads aren’t good people in the conventional sense. Theme: The people’s aspiration for a better life never changes
