In the steel forest of the city, young people Yan Yiming, Lin Kexin, Wu Dazhi and others are unwilling to be mediocre and pursue their own ideals and happiness. They have constant setbacks. Entrepreneurship failure, love difficulties, family pressure, and workplace difficulties. But they can always face everything with the power of humor, self-deprecation, and mutual support, and grow through laughter and tears. The four volumes progress layer by layer, describing the whole process from the end of school to the beginning of career, from the budding of friendship to each of them heading off to a distant place. In the end, they realized the declaration of "youth customization" in their own way: no matter the wind or rain, they can face life with a smile.
