After the apocalypse, human consciousness was uploaded to the digital abyss, leaving only Ji Chen still writing a suicide note. Lin Yuan was ordered to destroy these 'dangerous memories', but he heard his wife's voice between the lines. The deaf-mute mechanic Chen Ya repairs the terminal, the orphan Su Ni can read the emotions in the suicide note, and the funeral shopkeeper Lao Zhao hides the last activated receiver. When all the suicide notes lit up at the same time, they realized that it was not human beings who were writing suicide notes, but the forgotten consciousness that was writing their funerals.
