In Beijing, three families preparing for the college entrance examination are not only facing the pressure of going to school, but also facing the problem of parent-child relationship. Because of the contradictions between her mother Tong Wenjie (played by Haiqing) and her scumbag son Fang Yifan (played by Zhou Qi), his father Fang Yuan (played by Huang Lei) had to mediate left and right; Song Qian (played by Tao Hong), a single mother who refused to allow her ex-husband Qiao Weidong (played by Sha Yi) to invade the life of her mother and daughter, launched an all-encompassing concern for the life of her daughter Qiao Yingzi (played by Li Gengxi), and misunderstandings and contradictions quietly broke out unconsciously; The sudden care of his airborne father Ji Shengli (played by Wang Yanhui) and his mother Liu Jing (played by Yongmei) made Ji Yangyang (played by Guo Zifan), who had been raised by his uncle Liu Zheng (played by Ren Zhong) since childhood, at a loss, and the careful getting along between father and son did not bring peace to this relationship.
