When Su Wanqing died in a rented house in the late stage of cancer, her biggest regret was not that she had not enjoyed happiness, but that she had failed the rough officer Lu Zheng who had devoted everything to her in the 1970s. In her previous life, she thought he was dull, vulgar, and ignorant of romance, so she ran away with the educated youth who returned to the city. Little did she know that in order to give her a good life, beautiful clothes, and to join the army as early as possible without having to do farm work, he worked hard on tasks and stayed outside her house on New Year's Eve to deliver food stamps. In the end, he died heroically in a border conflict. Among his belongings was only a black-and-white photo of her when she was eighteen years old. When she opened her eyes, she was transported back to the educated youth spot in 1975. In front of her was Lu Zheng, who was wearing a washed-out military uniform and had strong features but a look of embarrassment. He had just finished delivering antipyretics to her in the rain, but he was soaked but did not dare to come in. This time, Su Wanqing threw herself into his arms with red eyes and tightly held the corner of his clothes: "Lu Zheng, you have to live well for me!" She used her reborn memories to secretly bring out her ancestral medical skills to treat the villagers' illnesses. She planted greenhouses, collected herbs, and led the villagers to grow herbs. She helped Lu Zheng avoid fatal crises in his previous life and helped him rise in the army. The rough officer doted on her and became a sweetheart. No matter how hard the training was, he would bring her wild fruits. When he was injured, he only dared to carry her behind his back to deal with it. Anyone who looked at her would glare back. In the 1970s when material was scarce, we supported each other, from the educated youth center to the military family home, from being young and ignorant to going both ways to stay together for a lifetime.
