Lin Wanqing, Su Yue, and Gu Manzhen are three thirty-year-old women who have been working hard in the fields of advertising, the Internet, and freelance art respectively. As creative director, Lin Wanqing sticks to her ideals despite customer difficulties and industry infighting; Su Yue, as a product manager, races against gender discrimination in the workplace and technological iteration; Gu Manzhen fights against the uncertainty of freelancing as an illustrator. The three people got together because of an environmental protection charity project. They supported each other in the collision of Yuanverse technology, AI tools and traditional industries, and finally broke through age anxiety and social disciplines, and redefined their self-worth. The story takes "female mutual help" as the main line, explores practical issues such as career promotion, emotional choices, and intergenerational conflicts, and conveys the core value of "thirty is not the end, but the starting point of awakening."
