Programmer Lin Feng accidentally transmigrates to the world of Love in the Courtyard in the 1960s after staying up late to binge-watch a show while working overtime. He becomes an ordinary steel mill worker and is bound to the Neighborhood Relations System, tasked with improving the residents' lives and fostering harmony among neighbors.
Among his neighbors are He Yuzhu, a chivalrous but simple-minded man; Qin Huairu, patient and shrewd; Xu Damao, a slippery schemer; and the courtyard's elder, Yi Zhonghai, who knows all the rules inside and out. With his modern-day wisdom and the System's golden finger, Lin Feng gradually resolves conflicts and overcomes difficulties, becoming the courtyard's resident problem-solver.
But as the Cultural Revolution sweeps in and the dawn of Reform and Opening-Up appears, life in the courtyard is carried along by the tides of history. How can Lin Feng use his abilities to change the residents' fates? And when everyone's happiness reaches its peak, will he truly be able to return to his own era?
Transmigrating into a courtyard house, where warmth and wisdom go hand in hand, even an ordinary person can build a bright future!
