The protagonist, former business manager of Mozhan Company. During the company's difficult period, she single-handedly revived the business, but after signing a major order, she only received a 500-yuan bonus and humiliation from boss Chen Lin. She resolutely resigned and took away Chen Lin's self-reliant three core backbones of technology, negotiation, and creativity—who were actually her best friends of ten years. The four of them joined hands to enter a new company, defeating Chen Lin's malicious order-snatching head-on in industry competition. Facing Chen Lin's public framing of her for stealing secrets and extorting money, she calmly produced ironclad evidence such as chat logs and resignation proofs, completely exposing his lies, ultimately bringing Chen Lin to legal justice and winning customer respect and a new career.
