Former top fashion pattern maker Gu Xingchuan resigned in indignation after taking the fall for his old company, Lanting, and went incognito to join Hexu Garments as a sample maker, just wanting to lie low and get through the days. Faced with workplace harassment and PUA from design director Wei Mingzhe, he repeatedly cracked difficult sample problems with his profound pattern-making skills, gradually winning the appreciation of boss Song Yuanan and the trust of his colleagues. Han Shaodong, the head of his old company Lanting, came over to poach him only to get publicly slapped in the face. In the end, Gu Xingchuan was promoted to chief pattern maker and technical partner of Hexu, leading the team to make a strong comeback amidst industry competition, and walking a path of workplace counterattack built on technical standing and refusing internal friction.
