Su Yanning has been working at Xingyue Media for half a year. One day, business partner Huo Linchuan rushes to the company, publicly questioning her for pretending not to know him and accusing her of taking money without doing the work. Chat screenshots, transfer records, stolen photos, a matching fountain pen—all the evidence falls upon her as if meticulously calculated. Meng Shuran, a senior colleague who usually takes care of her, also steps forward to testify that she has a second account. Just as she is almost deemed problematic by the entire company, newly appointed Technical Director Gu Xubai takes over the investigation. He checks computers, logs, express deliveries, and payment records, discovering that every single clue has been arranged in advance.
