The shrewd and capable workplace elite Lei Li, the gentle and beautiful full-time housewife Ren Duomei, and the invisible rich girl Shen Jianan, who strives to prove themselves, were originally of different ages, different personalities, and had no intersecting experiences, but they became close friends who knew each other and loved each other at important points in their lives facing difficulties in the workplace and life. From speculating about each other to gradually accepting each other, from facing each other alone to opening up to each other, from fighting alone to supporting each other, three brave, strong, and full of wisdom and strength of modern urban women finally worked together to solve various problems and confusions in each other's lives, and witnessed each other's growth and transformation. After thousands of sails, the three of them not only tore off the inherent labels attached to women by the outside world with their own efforts, but also bravely opened up a career of self-realization, just like three movements with different tunes intertwined together, playing a wonderful music of life.
