The story begins with 35-year-old Chen Xi holding her third divorce certificate and her 6-year-old son Zhou Nian'an (later renamed Chen Xingyu; nickname: Xiaoyu) standing in front of a bankrupt shop and recalling the past - this was her "certificate of submission" to come to this city for her third husband, but now it has become a joke. The whole book takes "divorce certificates are scars, and sugar is sweetness earned by oneself" as the core clue, and connects the four stages of "trauma review - survival in desperate situations - counterattack - meeting the right fate", and uses the contrast of "how painful the first half is, how happy the second half will be" to highlight the core of the refreshing text of "women break through the situation on their own".
