In Star Port, which is tightly controlled by the "Order Bureau", history is woven into a unified and stable grand narrative, and any dissent is regarded as "disorder" and erased. The young historian Lin Zhao, a soul seeking stability in the pile of old papers, was accidentally assigned to organize an "unrecorded file" from a dusty secret room. In these files, he discovered a deliberately forgotten melody, a forbidden song about "falling stars."
As the pieces of the truth gradually came together, Lin Zhao found himself involved in a conspiracy that spanned a century. He must choose between loyalty and curiosity, personal safety and collective memory. Around that ancient ballad, a new trend of thought that has been suppressed for a long time is about to move, and the defenders of the old order are following closely. Every step Lin Zhao takes will reveal more cruel truths about the mystery of the creation of Star Port, and ultimately determine the fate of the city and the destination of his own free will.
