When the genius detective Shen Zhou discovered transparent fragments and blood stains at the scene of the theft of "Tears of the Siren", he never expected that the end of the trace would be Xu Qingran, the son of his old friend. The boy who disappeared three years ago is now a thief, leaving behind gear-patterned buttons and star map codes to guide him into the fog of old cases. On the lighthouse, Xu Qingran risked his life in exchange for hard drive evidence, but left behind a mysterious invitation to "see you tomorrow". Shen Zhou was tearing apart the truth between the files and Xinghui, but he didn't know that as the gears turned, their youthful bond had already become a key piece in the game.
Concept: Growth and redemption are intertwined in emotional tearing, and the collision of fate and human nature
