Modern CEO Shen Yanzhi unexpectedly transmigrates to a world of male spouses, where he becomes the son of a down-and-out merchant. He uses modern knowledge to improve the family's poor farmland, catching the interest of Su Mingjin, the tutor's son. The two grow closer through long talks in the library and working together to aid flood victims. They go on to rebuild their home, establish a village school, and travel to take the imperial examinations, deepening their bond all the while. While developing farming back in their hometown, Yanzhi unexpectedly reveals that he is a transmigrator and confesses his love. Mingjin accepts him. But their relationship faces opposition from the clan and harassment from the county magistrate. In the midst of the crisis, Yanzhi draws on his modern way of thinking to overcome their difficulties. Later, the farming methods they improve win the court's approval. The two establish an academy, adopt children, and remain by each other's side for life. Even in his old age, Yanzhi writes with deep affection, “I crossed a thousand years just to meet you.”
