After the death of her grandmother, 28-year-old Lin Qian inherited an antique shop - "Time Repair Shop" located deep in the alleys of the old city. My grandmother left her last words: Every old thing hides unfinished love, and repairing them is to repair the bond between people. Lin Qian didn't believe it at first, until she restored an old pocket watch and reunited an old couple who had been separated for thirty years due to misunderstanding. She gradually discovered that she could resonate with the remaining emotions in old things. The appearance of the mysterious antique appraiser Shen Moyan makes everything more complicated - he seems to know the secret of this store, but deliberately hides it. In the process of repairing old things again and again, the two uncovered each other's hidden traumas and quietly entered each other's hearts.
