In a cyberpunk city where memories can be backed up, traded or even stolen, the promising neuroscientist Ling Yuan has become a "memory scavenger" - specializing in dealing with the dirty and messy digital memories abandoned by others. His only spiritual support is to reflect on the last beautiful memory left by his deceased sister every day.
When this precious memory is erased by a mysterious force, his world collapses.
In order to recover the stolen past, Ling Yuan was forced to step into the bizarre black market of memories and reach a dangerous deal with the femme fatale-like intelligence dealer "Phantom". Every step he takes deeper brings him closer to the truth and closer to the abyss. He discovered that his sister's death was not an accident, but was closely related to the "God Plan" of the "Eternal Heart", the technology giant that controls the world, that subverts human existence.
When personal obsessions intertwine with the fate of all mankind, and when deeply loved memories turn into the most terrifying weapons, Ling Yuan must make a choice: to take back his own sweet memories or indulge in false happiness? Or embrace the cruel truth and fight for freedom in the cold reality?
This is a story about love, loss and redemption. In the abyss of memory, who are you?
