In this international city "Liu Li City" built of steel and glass, a strange phenomenon called "memory reverberation" is circulating. Lin Mo, a rare "memory restorer", makes a living by touching and repairing these memory fragments that carry secrets. By chance, he took over a seemingly ordinary lovelorn commission, but deep in the debris, he came across a dark memory that was deliberately erased and related to the foundation of the city. When the outline of the truth gradually becomes clear, the invisible pursuit has followed. A mysterious organization called the "Order" vowed to make him disappear along with that memory. When the memories were pieced together, Lin Mo was forced to stand at a crossroads of fate: Should he uncover the truth that could subvert everything, or bury it with his own hands and protect the city's false peace?
