Ran Jinnian dies in poverty and abuse on the streets of Guangzhou, having abandoned her devoted childhood sweetheart, Lu Jinyuan, for a charming but deceitful man named Song Zehan. In her final moments, she regrets her foolishness, realizing that Lu Jinyuan, who waited for her and never married, was the only one who truly loved her. She awakens to find herself reborn on her wedding day in 1972, the very day she had previously run away with Song Zehan. This time, she resolves to marry Lu Jinyuan and make amends for her past mistakes. Her mother, Wang Xiumei, is relieved when Ran Jinnian agrees to the marriage without resistance, unaware of the daughter's internal transformation.
The wedding proceeds smoothly, and Ran Jinnian is struck by Lu Jinyuan’s quiet devotion. He is a military officer who has harbored feelings for her since childhood, a fact revealed by his mother. Their wedding night is tender, contrasting sharply with the violence and neglect she endured in her previous life. Shortly after the marriage, Ran Jinnian discovers a supernatural space attached to a jade bracelet she received as a gift. The space contains an infinite supply of goods, including food, medicine, and daily necessities, originating from a previous reborn owner. This discovery gives her the means to improve her life and protect her family.
Ran Jinnian encounters Song Zehan, who attempts to lure her into eloping again, promising wealth and adventure. Instead of falling for his lies, she plays along, giving him a small amount of money to lower his guard. She then anonymously reports his illegal trading activities to the public security bureau, knowing that in this era, such crimes are punished severely. Song Zehan is arrested and sentenced to labor reform, removing the threat he posed to her new life. Meanwhile, Lu Jinyuan is assigned to a dangerous, year-long mission. Before leaving, he expresses his desire for Ran Jinnian to join him at the military base, but she is already pregnant with their child.
During Lu Jinyuan’s absence, Ran Jinnian lives a peaceful life with his mother, managing the household and using her spatial abilities to ensure her family is well-fed and healthy. She hides her secret from everyone except Lu Jinyuan, whom she trusts completely. When he returns early after completing his mission, he discovers her pregnancy and the source of their abundant supplies. Rather than being alarmed, he vows to protect her secret, recognizing the danger it could pose if revealed. The couple decides to move to the military base together, despite the hardships of her advanced pregnancy.
Upon arriving at the southern border military compound, Ran Jinnian faces the realities of military life. She is greeted by Lu Jinyuan’s comrades, Song Mingyi and Lin Beixiao, though tensions exist due to a misunderstanding involving a missed telegram. Yan Qingxue, the political commissar’s daughter and a former admirer of Lu Jinyuan, is disappointed to learn of his marriage and pregnancy. Ran Jinnian navigates these social dynamics with grace, earning the respect of her new community. However, a prenatal checkup reveals that she suffers from severe anemia, and the baby is smaller than expected. The doctor warns of potential complications during delivery. Determined to ensure a healthy birth, Ran Jinnian uses her spatial supplies to improve her diet and health, preparing for the challenges ahead while building a life with the man who has loved her since childhood.
