Xu Yan originally had good intentions in preparing healthy lunches for her colleagues, but because of a single meal, she was criticized, schemed against, and even slandered for taking their money to improve her own life. She chose to refund the money on the spot, put an end to the endless exploitation, and no longer endured moral kidnapping in the workplace. Afterwards, the department manager handed over the data model she had painstakingly built to Lin Sisi, attempting to let the other party steal the credit for the project. Faced with injustice, Xu Yan did not give up on herself, but instead relied on solid professional skills, a clear judgment, and an attitude of adhering to principles, step by step exposing the lies and winning recognition from clients.
