Ordinary college student Xu Nian is responsible for organizing the graduation teacher appreciation banquet. To steal the spotlight, class monitor Lin Zhi uses AI to book a luxurious private dining room and forces Xu Nian to cancel the three large tables she had originally reserved. When they arrive at the restaurant, they discover that no reservation exists. Lin Zhi then turns around and blames Xu Nian for failing to do her job. In her previous life, Xu Nian maxed out her father's credit card to save the event, only to be cursed and accused by the entire class. Even worse, her mother missed the emergency treatment payment and tragically died. Reborn on the night before the banquet, Xu Nian decides to keep her trump cards hidden, record conversations as evidence, and gather proof from multiple sources. In front of everyone, she exposes Lin Zhi's true colors: embezzling class funds to buy luxury goods and passing off empty gift boxes as teacher appreciation gifts. The hypocritical class monitor is finally disgraced and utterly ruined.
