Gao Jie (played by Janice Man) has always regarded becoming a jewelry designer as her lifelong dream. During her internship in a mine in South America, Gao Jie met a man named Yu Zhi (played by Zhang Ming'en). Coincidentally, Yu Zhi is the heir of Shengfeng Gold Jewelry, a leading gold shop in China. After that, Gao Jie returned to China, but the reality was much paler than she had imagined. Gao Jie joined Shengfeng Gold Jewelry, but Shengfeng Gold Jewelry focused on traditional Chinese craft jewelry and was hit too hard by Western jewelry brands, and the entire company was on the verge of collapse. Seeing this, Gao Jie decisively set up a mosaic group, focusing on Western jewelry, and integrating Chinese accessories with Western jewelry, opening up a new world in the jewelry market. During this period, Gao Jie and Yu Zhi also collided with romantic sparks.
