The novel tells the story of Lin Wanzhao, a person with the ability to "remember by touching objects". He can glimpse the forgotten emotional fragments of others by touching old objects with his fingertips. However, due to "empathy overload", he lives as a memory scavenger; Shen Yubai, a professor of cold psychology, suffers from "emotional amnesia" and forgets important emotional experiences. Even his heartbeats become blank files. He entrusted Lin Wanzhao to retrieve his father's memory, but when he touched the old things, he found that her fingertips were the only warm light that could shine into his blank world. From tentative cooperation to life-and-death dependence, the two piece together the broken past to fight against the curse of forgetfulness, and at the same time confirm that each other is the only exception in the flashbacks of old things - her fingertips read minds, and his blank world will eventually be turned into poetry by this two-way redemption.
