This is an era where dreams shine, but it is also a time where ideals cool; it is the worst of times and the best of times, this is our youth era. It is a story of a group of fashionable young people in the current times, a genuine portrayal of their lives, and a microcosm of our era. The story unfolds in Shanghai during a period of rapid economic development, where four girls - Lin Xiao (played by Yang Mi), Gu Li (played by Guo Caijie), Nan Xiang (played by Guo Biting), and Tang Wanru (played by Xie Yilin) - live, study, work, and grow in this beautiful and fashionable city. The four girls share a deep bond since childhood, yet each has different values and perspectives on life. As they live together in the same dormitory, their calm lives face endless challenges in the later stages of their university life, including the busy search for jobs and internships, accompanied by tremendous survival pressure. What seems like a peaceful campus life soon encounters various unexpected issues that leave them at a loss on how to cope and choices to make. Meanwhile, a group of boys, including Gu Yuan (played by Ke ZhenDong), Jian Xi (played by Li Yueming), Gong Ming (played by Feng Xiaoyue), Chong Guang (played by Chen Xue Dong), Wei Hai (played by Du Tianhao), and Xi Cheng (played by Jiang Chao), are also entangled in complicated emotional relationships with these four girls... Faced with immense survival pressures and intricate emotional entanglements, the four girls must go through significant transformations in friendship, love, and even family ties. In the face of great changes, will they still hold on to their attitudes towards life? How will their youth stories continue with brilliance? This film is adapted from the bestselling novel 'Small Times' of the same name, with Guo Jingming personally penning the screenplay and making his directorial debut.
