It mainly tells the story of Qin Xinyue, a criminal policeman who has made great achievements, and Li Huaishu, a childhood playmate who has been separated for many years and the new county magistrate of L County, who unexpectedly reunited during a mining disaster rescue.
Many years ago, Li Huaishu left for a foreign country due to family changes, leaving behind unspoken promises; Qin Xinyue joined criminal investigation after graduating from the police academy, but lost her beloved Yao Zhe during an undercover mission. From then on, she trapped herself in the shadow of the past, numbing her heart with crazy work.
The emergency rescue at the mine disaster site reawakened the dust-laden memories of the two - he remembered her favorite tin frog when she was a child, and she could not forget the toffee he secretly stuffed her. He came back with worries that had not changed for many years, but she wrapped up her pain and built a high wall.
In my hometown of L County, the past and present are constantly intertwined. Li Huaishu's silent protection, Qin Xinyue's struggle and relief, as well as the misunderstandings and affection hidden in time, gradually unfolded as the story behind the mining disaster unfolded. When childhood memories encounter real responsibilities, when old scars encounter new tenderness, can they find the courage to reconcile with the past in each other's company, and let their belated intentions take root again?
