My partner was the first factory manager.

Shen Qinglan, the factory manager of a textile factory during the Republic of China era, unexpectedly travels to Yangpu District, Shanghai in 2026. She discovers that the young man giving a presentation on stage bears the striking resemblance to her lover from a past life, while the investor in the audience is her nemesis from that time. Using her exceptional calculation skills and business management abilities, she exposes the scam in public and saves the day. To help Lin Xiaochen, who looks exactly like her boyfriend from her past life, Shen Qinglan is willing to give her all. Facing misunderstandings within the team, technical obstacles, and online controversy, the two go from mutual doubt to mutual trust, overcoming adversity step by step. This encounter across time integrates the spirit of a century-old industrial enterprise with the contemporary wave of scientific and technological innovation, ultimately leading to success in both career and love.
