Lin Wei from the Marketing Department of Shengyuan Group has transformed from an intern to a business backbone with five years of hard work. She stood out with her professionalism and composure during a key cooperation negotiation. She not only won the cooperation, but also gained promotion opportunities and an olive branch from top companies in the industry. After being promoted to deputy director, she not only had to deal with the undercurrent of disputes in the workplace and the complicated mentality of her colleagues, but also had to choose between familiar tracks and unknown opportunities. At the same time, the contradiction between her mother's nagging of marriage and her personal career pursuit also made her continue to search for balance in the reinforced concrete city. This is a story about women in the workplace adhering to the edges and corners as they grow up, clarifying their direction in their choices, and writing their own progress and light in the morning light and night.
