Shen Que, the architect of the memory palace, can recall any memory fragment he has handled at any time. In order to pay for her mother's sky-high medical expenses, she started a live broadcast anonymously, specifically accepting "scum detection" commissions. By recreating memory details, she helped the client see the true appearance of his partner. The business was booming until an encrypted number sent a commission and a deposit, asking for an analysis of whether his fiancée was faithful. Shen Que clicked on the memory file sent by the other party. In the high-definition video, the woman trying on a wedding dress was clearly herself.
