This is the story of four female classmates and best friends. Yu Hang, Su Qingxue, Guo Xiaoling and Aimei, four people born in the 1970s, returned to the city where they were born and raised after graduation and all have good jobs. Born into different families, they have different life paths. One has everything going smoothly, getting married and establishing a career, but faces betrayal; one falls in love with the wrong person and has endless consequences; one marries into a rich family but cannot get family affection; one simply remains single, but does not guard against finding his old love. These are four ordinary women who only want ordinary happiness, but it is so difficult to get it. Holding your son's hand and growing old with him is just a beautiful wish in an ancient poem? Perhaps, happiness does not distinguish between ordinary and great, but happiness is equally rare no matter who it is with, and there is never perfect happiness. However, no matter what, pursuing happiness with the original intention is happiness and what makes ordinary people extraordinary. Whether it is right or wrong, I will tell you slowly and listen to it, and I will think about it carefully with you.
