Summary：Nanxi Ancient City is separated by a river. On one side is the old city with small families, and on the other side is the new city with tall buildings. 26-year-old Mingzhu Shen lives in the old city, and her parents run a small restaurant. Her boyfriend Jianqi Feng lives in the new city, and his parents run a big company. The two fell in love and got married, but because of the mismatch between the two families, they were strongly opposed by the Feng family. The two families broke up unhappily because of the wedding arrangements. Unexpectedly, Jianqi Feng died accidentally while saving a child who fell into the water, and the Feng family begged Mingzhu Shen to give birth to the child. "To have a baby or not" became a problem facing Mingzhu Shen. At the same time, Mingzhu's biological parents Jingxiang Yu and Dacheng Xu came to find her. The appearance of her biological parents made Mingzhu Shen's life more chaotic, but she also met her biological sister Zhixia Xu, her brother Zhidong Xu and his sister-in-law Chen Bi, and received love from both her biological parents and adoptive parents. After some entanglement, Mingzhu Shen decided to give birth to the child, but her father-in-law died of a heart attack, the company was insolvent, and the generous conditions originally provided by the Feng family turned into a pile of debts. Mingzhu Shen's life fell to the bottom again. This time everyone advised Mingzhu to abort the child, but she was determined to protect the fetus in her belly. Zhixia Xu was worried about her unmotivated husband and the upcoming second child; Chen Bi was pressed for a gift because of her pregnancy, and the young couple almost separated; Jianqi Feng's sister Meiqi Feng accidentally became pregnant due to a romantic encounter. The four "pregnant" women ushered in their due dates together in the noisy life. In the days to come, they will still quarrel and fight, but they will also support each other through the years and experience life.
