The story takes place in 1976. Su Yang (Xu Baihui), an educated youth who went to the countryside, fell in love with a man named Zheng Xiangdong (Zhang Bo). However, this relationship eventually went their separate ways after many ups and downs. Su Yang was heartbroken. At this time, she was accompanied by Si Mengnan (Ren Donglin), who had always liked Su Yang silently. With the latter's company, Su Yang's inner wounds gradually healed, and the two came together naturally. Unfortunately, Si Mengnan did not cherish this hard-won relationship. Under his constant hurt and betrayal, the scarred Su Yang chose to leave. During the educated youth era, Su Yang once studied sewing and clothing design, and this specialty brought a ray of hope to her desperate life. In a blink of an eye, decades later, Su Yang became a giant in the clothing industry with her hard work and craftsmanship, but there was always an unsolvable knot in her heart. It was about Zheng Xiangdong and the child she thought she had lost but unexpectedly lived in the world.
