Xingtu Advertising Co., Ltd. - A top advertising company in China, famous for its high-intensity work, brutal competition and high-quality resources. The Creative Department is the company's "ace department", led by Su Wanqing, and undertakes advertising planning for well-known domestic and foreign brands. In the summer of 2024, the industry was intensified and the company was facing major personnel adjustments. Su Wanqing's retirement application was temporarily rejected, requiring her to take over the last batch of interns before leaving. As an "alien" among the interns, Lin Chen broke into this hierarchical workplace with the energy of a newborn, and started a love-hate entanglement spanning 26 years with Director Bingshan who was "counting down to retirement".
