Jiang Tang accidentally transmigrates into a campus novel written by her best friend, becoming the gold-digging ex-girlfriend of the male lead, just as the story has set her up to be. She is also bound to a book-transmigration system. Originally, she intends to maintain her gold-digger persona, rack up expenses on the male lead's credit card, and leave once she meets the requirements to collect a nine-digit breakup settlement. However, Shen Xiunian, a physics genius, breaks away from his original cold and aloof characterization, treating her with extraordinary tenderness and affection while remembering every little thing about her. Through their many dates and moments together, Jiang Tang gradually develops genuine feelings and becomes immersed in their beautiful romance. But who could have guessed that the system calculates mission completion based on the number of dates? Once she completes the mission, Jiang Tang is forced to face an unexpected breakup.
