Three girls who have had a revolutionary friendship for more than 20 years.
Several relationships that come and go.
Yu Ze: "If you make a mistake once, there is no possibility of looking back."
Zheng Shuo: "I thought we could do it, why can't we go back to the past."
Lin Chuang: "If you are tired, come back, I will still be waiting here, you can see it."
Bai Yixun: "Woman, can you not be so difficult?"
Shen hope: "Which is more important, your woman or your man."
The promises made when we were young are the choices we face when we grow up.
How to be happy, how to love.
