This episode tells the story of female scientist Lin Xi, who unexpectedly travels back to 1977 on the day she receives the "Nobel Prize." She becomes a girl who is drugged by her adoptive mother, Zhen E'nv, and intended to be sent to Production Team Leader Hao Jiannan for assault. Lin Xi, relying on her intelligence and composure, escapes just as the drug takes effect and jumps into the river to save herself. In a moment of crisis, she is rescued by Shen Huaichuan, the farm director, who happens to be passing by. However, the next morning, Hao Jiannan and Zhen E'nv come to their door. Hao Jiannan misunderstands Shen Huaichuan to be involved with Lin Xi, confronts him on the spot, and a new conflict is about to erupt.

Modern chemist Lin Xi travels to a novel set in a past era and is immediately framed by her adoptive mother, Zhen E'nv, and scoundrel Hao Jiannan, who try to drug her. To escape the predicament of being falsely accused of promiscuity, the male lead, Shen Huaichuan, decisively announces their love and they quickly marry. After the wedding, Shen Huaichuan pretends to be a simple breeder with two children to test Lin Xi. Believing it to be a marriage of convenience, Lin Xi readily agrees without concern. However, Director Tian, Shen Huaichuan's subordinate, suddenly appears, revealing his true identity as the factory director of a state-run farm, adding a new twist to their relationship.

The episode opens with chemist Lin Xi arriving at the state-run farm with her husband, Shen Huaichuan. Lin Xi is curious why Shen Huaichuan is referred to as "Director," but he casually dismisses it as a nickname. However, after Lin Xi leaves, Shen Huaichuan immediately reveals his true identity to his subordinate, Director Tian – he is secretly investigating the "farm machinery theft case" and instructs his subordinate to keep a close watch on the suspect, Hao Jiannan. That evening, in their humble new home, Shen Huaichuan confesses to Lin Xi that they are indeed husband and wife. He then surprises her by introducing two children, Yi'er and Bao'er, as her new children. The episode ends with Lin Xi's shocked expression.

The episode opens with adopted son Yi'er and adopted daughter Bao'er intentionally staging a "poor family" act in front of their newly met adoptive mother, Lin Xi, as part of their father's plan. They exaggerate their family's financial struggles, making Lin Xi believe them. Husband Shen Huaichuan plays along, but his words inadvertently reveal cracks in the facade. The kind and responsible Lin Xi is deeply moved and decides to work at a farm to supplement the household income. The couple, bound by the shared secret of their "hidden identities," experiences a series of heartwarming and amusing misunderstandings amidst the nostalgic atmosphere of their daily life.

After sharing a bed with Shen Huaichuan, Lin Xi reacts with embarrassment. Shen Huaichuan flees in a panic, leading Lin Xi to believe she scared him off. Outside the door, adopted son Yi'er and daughter Bao'er innocently discuss how to get their parents to have a younger sibling. Later, Shen Huaichuan brings news of a farm ranger recruitment, and Lin Xi is thrilled to discover the pesticide application job perfectly matches her chemistry background. Full of energy, she goes to apply, impressing Shen Huaichuan.

The episode opens with the villain Hao Jiannan furious at being tricked by Lin Xi. Lin Xi's adoptive mother, Zhen Enü, seizes the opportunity to offer advice, instigating Hao Jiannan, the production team leader, to retaliate when Lin Xi applies for a job. Subsequently, Zhen Enü's biological son, Lin Quédé, confronts his mother in anger after Lin Xi (who was originally his child bride) is "sold" by his mother for a dowry. However, Zhen Enü dismisses his concerns, further fueling her hatred for Lin Xi. The scene shifts as Lin Xi heads to the factory to apply for a forest ranger position, only to run into Hao Jiannan, who is there to secure the job for his younger brother. Hao Jiannan recognizes her on the spot and publicly humiliates her, igniting an immediate conflict.

This episode follows Lin Xi, the protagonist, as she faces unfair treatment during her application for a forest ranger position at the state-run farm. Production team leader Hao Jiannan and his brother Hao Jianren use their authority to try and secure the position for their own family. Hao Jiannan not only publicly humiliates Lin Xi but also insults her husband, Shen Huaichuan. As the conflict escalates, Shen Huaichuan appears to support his wife and confronts the bullying Hao Jiannan. At a critical moment, the newly appointed Office Director Tian arrives. Shen Huaichuan (whose true identity is the new factory director) seizes the opportunity to recommend Lin Xi. Director Tian immediately approves, turning the situation around and thwarting the Hao brothers' scheme.

To compete for the position of orchard ranger, Lin Xi publicly exposed Hao Jiannan and his brother's attempt to pre-determine the job and proposed a fair competition with the bet of "curing the wilting fruit trees." Hao Jiannan escalated the bet, stating that if Lin Xi lost, her husband Shen Huaichuan would be fired. Shen Huaichuan outwardly agreed but privately arranged for Director Tian to investigate Hao Jiannan's patron, the deputy factory director. Facing her husband's concerns, Lin Xi showed strong confidence and, in turn, reassured Shen Huaichuan, saying she could win easily.

The female lead, Lin Xi, shows her husband, Shen Huaichuan, the new organic pesticide she developed. They go to the orchard to test it, sharing sweet moments. Unexpectedly, production team leader Hao Jiannan suddenly appears, accusing them of poisoning the fruit trees with the pesticide. The villain Fang Ming and the deputy factory director also arrive one after another, colluding to frame Lin Xi and Shen Huaichuan for "damaging state property" and ordering their arrest. Faced with the sudden crisis and false accusations, Lin Xi remains unusually calm, hinting that the situation is not out of her control.
