Deep in Wutong Lane in the old city, Lin Shiwei, a restorer of old objects, runs the "Cherishing Objects Workshop". She can sense the powerful emotional memories held by old objects when she touches them - it's her secret, and it's an ability that comes at a price. The technology company "Future Sense" won the bid for the Wutong Lane renovation project, and the person in charge, Lu Yushen, met Shi Wei during the visit.
The two of them pursued a set of old photos and a snuff bottle side by side: the corners in the photos and the abnormal traces on the snuff bottle sandwich mutually corroborated with the emotional echo triggered by Shi Wei, creating a research thread that was deliberately sealed.
Lu Yu practiced rationality and restraint, but was always determined to uncover the truth behind his mother Shen Qingyin's disappearance. The deeper the investigation, the more he became certain that his mother had participated in the "Temporal Echo Project", and Shi Wei's ability was an important proof of the plan.
The two went from testing each other to reaching cooperation: she provided the direction of the memory fragments, and he was responsible for putting the fragments into a verifiable evidence chain.
When various doubts emerged, Lu Yushen chose to stand in front of her at his own expense and openly confront the forces in the dark.
Love and memory are redefined in the echo.
Purpose: Memory should not be possessed or manipulated, but should be understood and treated kindly; on the way to pursue the truth, learn to guard boundaries, repair trauma, let the past be laid aside, and let people move towards new life.
