To myself in 1999

15-year-old "good girl" Qian Jiayue was admitted to a key high school in the market, and began to face various learning challenges, and her confession plan to her neighbor's big brother and honor Xiao Han also ended in failure. The godbrother is clever but always gets into trouble. Qian Jiayue met Chen Mo, a new friend with a sassy personality, and the girls grew up in friendship. At the same time, parents are experiencing a series of life changes such as family crises and family restructuring. After Chen Xiu'e returned to the city, because she was not by Qian Jiayue's side for a long time, there was a gap between mother and daughter. When her grandmother, Mrs. Chen, passed away, the emotional entanglement between three generations of mother and daughter was resolved. Chen Pengyu prides himself on being an elite, but he has cultivated a "discouraged" and rebellious daughter Chen Mo, and after the father-daughter conflict, he also realized that a generation has a generation's "mission". The strong Ai Ping raised Xiao Han alone after being laid off, and the "little boss" Zhang Qiming learned to get along with his naughty son Maotou, and reorganized his family with Ai Ping after several twists and turns. Times are changing, but the warm family affection remains the same, and the warmth of the neighbors and neighbors taking care of each other remains the same.
