This drama is adapted from the Douban Reading serial novel "180 Days Accompanying Birth Plan", written by Chu Tang. After experiencing the double blow of a broken heart and unemployment, 28-year-old Gu Yunsu (played by Zhou Yutong) chose to go home to find her mother without hesitation when she was confused about the future and could not find the direction of life; Gu Yunsu, who originally planned to "eat the old man", became the close caregiver of the "rebellious" mother Wu Limei (played by Wu Yue) without any preparation. The new mother-daughter relationship and abstract mode of getting along between the "real mother" daughter born in the 1990s and the "girlfriend" mother born in the 1970s, accompanied by the new members of the reorganized family, staged a series of hilarious and warm and healing family stories. During the 180 days of accompanying the birth, Gu Yunsu gradually realized the deep dependence and cherishment on his mother, and Wu Limei also had a real experience of her daughter as a "little cotton-padded jacket". Gu Yunsu welcomed the addition of new family members in the company of warm family affection and sweet love, and also found a new direction for career and life.
