In the fast-paced city, four young people with very different personalities travel together: Su Ranran uses jokes to dodge the sledgehammer of life, Lin Ze'an struggles with coffee and ideals, Shen Xiaolu grows up in the gap between career and family, Zhao Dabao is willing to create happiness, but will eventually face his own problems. Faced with the test of friendship, the twists and turns of relationships, the ups and downs of career and the uncertainty of family, they accompany and help each other through laughter and tears. The three volumes of the story take the intertwined growth of the four people as the main line, with a mixture of sorrow and joy, and energy bursting out from the fragments. The daily life of a chicken feather witnesses the extraordinary value of youth and ideals blooming in the real world.
