He Cheng, a young man who stumbles and struggles in the city, with his immortal dream and a group of friends who are also on the edge, staged scenes of poignant, passionate, funny and tender stories in his daily life in a 24-hour convenience store. From trivial matters in the city to the big test of life, they endured frustration but refused to shed tears in the urban gap where absurdity and reality coexisted, and faced the ups and downs of life with a smile. The three volumes describe how they went from frustration and confusion to self-acceptance, and found their own urban destination in friendship, love, family and ideals.
