A Married Couple Transmigrates to the 1970s: Sharing a Dual Sign-In System

He Qiutang, a woman from the twenty-first century, transmigrates into the body of an eighteen-year-old girl in Beijing during the autumn of 1970. The original owner, the youngest daughter of the He family, had just graduated high school and was expected to be sent down to the countryside. However, her mother, Shen Lanxiang, fiercely opposed this, having worked hard to secure a city life for her children. The He family enjoys a relatively comfortable existence compared to their neighbors, with Shen Lanxiang managing the household finances after her husband’s death. He Qiutang discovers she possesses a storage space ability, allowing her to store and retrieve items at will. Her immediate concern is avoiding the rural assignment, as she knows the hardships awaiting those who leave the city. She also realizes the original owner was being manipulated by a man named Xu Zikai, who intended to use her family’s resources before abandoning her in the countryside.

Simultaneously, Zhao Huaian, He Qiutang’s husband from her previous life, also transmigrates into this era. He inhabits the body of a young man from a large, financially strained family in the machinery factory district. Zhao Huaian awakens with a "daily check-in system" that grants him items based on location, though he initially cannot locate the storage interface for these rewards. He discovers that his system is linked to He Qiutang’s; items he checks in appear in her storage space. The two reunite unexpectedly at a state-owned restaurant, recognizing each other despite the changed circumstances. They quickly establish a partnership, sharing their unique abilities and strategies for survival in the planned economy of the 1970s.

Zhao Huaian leverages his modern driving and vehicle repair skills to secure a job as a truck driver at the transport company. His talent impresses his superiors, leading to a rapid promotion and assignment to delivery routes around Beijing. This provides him with a stable income and the mobility needed to navigate the city. Meanwhile, He Qiutang prepares for a recruitment exam at a daily necessities factory, guided by her eldest sister, He Suqin. The exam focuses not only on technical knowledge but also on political stance and moral character, reflecting the turbulent social climate of the time. He Qiutang passes the exam and secures a position as a quality administrator, ensuring she remains in the city.

The couple faces external pressures from neighbors and former acquaintances. Xu Zikai, rejected by He Qiutang, attempts to damage her reputation by spreading rumors through their mutual friend, Yu Sui Sui. Neighbors, envious of the He family’s relative prosperity, also gossip and threaten to report them to the neighborhood committee. Zhao Huaian deals with his own family’s internal conflicts, particularly with his eldest brother and sister-in-law, who are perceived as greedy and manipulative. He decides to move out into a company dormitory to maintain independence and protect his marriage from familial interference.

As they settle into their new roles, He Qiutang and Zhao Huaian continue to utilize their systems to improve their living standards. Zhao Huaian’s driving routes allow him to check in at various locations, obtaining food and supplies that he shares with his wife. Their secret meetings become a routine, providing emotional support and strategic planning for their future. The story establishes their foundation for navigating the challenges of the era, relying on their modern knowledge, supernatural advantages, and mutual trust to secure a stable life in 1970s Beijing.
