In 1972, the day when young worker Zhang Yongkang became a brocade weaving worker, he held a unique wedding with his beloved girl Su Weici without telling anyone. However, this plan was disrupted by his competitor Zou Dike. In an instant, several young men and women were pushed into an awkward and contradictory position: Erya insisted on loving Zhang Yongkang and tried every means to win his affection, while pure and faithful Su Weici was also unwilling to give up her love. Fate took a huge turn at a critical moment: Su Weici's somewhat mysterious origin was suddenly exposed. As the daughter of a "traitor," in order to protect her lover, she reluctantly gave up her first love and married Zou Dike against her will.
