This is the story of Qin Xinyue, a decorated criminal police officer, and Li Huaishu, the newly appointed county magistrate of L County, who unexpectedly reunite during a mine rescue after years apart.
Years ago, a family upheaval forced Li Huaishu to leave home, leaving behind a promise he never got to make. After graduating from police academy, Qin Xinyue devoted herself to criminal investigation, but lost her beloved Yao Zhe during an undercover mission. Ever since, she has trapped herself in the shadows of the past, burying her feelings in an endless workload.
The emergency rescue at the mine brings their buried memories back to life. He remembers the tin frog she loved as a child; she cannot forget the milk candies he once secretly slipped to her. He has returned with the same devotion he has carried for years, while she has built a wall around herself, fortified by pain.
On the soil of their hometown, L County, past and present keep intertwining. Li Huaishu's quiet protection, Qin Xinyue's struggle to let go, and the misunderstandings and deep affection hidden in the passage of time all come to light as the story behind the mine disaster unfolds. When childhood memories meet the responsibilities of the present, and old wounds encounter new tenderness, can they find the courage to reconcile with the past in each other's company and let their long-delayed feelings take root again?
