Su Zimo, Lin Zhiyu and their friends struggle for love, friendship, dreams and family in a bizarre modern city. From the overt and covert struggles in the office building to the failure of starting a business and then getting up again, from family conflicts to the reunion after breaking up, they are constantly colliding between ideals and reality, secularity and persistence. Everyone has an unspeakable "hidden compartment" - hidden dreams and regrets. In the ups and downs and relaxed and humorous daily life, everyone grows up slowly and looks for their own glimmer of light in the sea of city people. In the three volumes of the book, from youth to precipitation, everyone finds the rhythm of dancing alone and walking together, and finally embraces new life after the storm.
