In this memory-driven city "Eitelberg", the past can be sold, skills can be purchased, and happiness has a clear price tag. Kyle, a memory weaver who lives in seclusion in the "grey area" at the bottom of the city, makes a living by repairing the broken pasts of others, but has a blank memory of his own past.
A commission from the mysterious aristocratic woman Ilara dragged him into a deadly whirlpool. A memory crystal that was violently erased is not only the key to the top secrets of the "Clock Tower", the center of power, but is also inextricably linked to Kyle's lost identity.
When the pursuit of the "Time Watchers" ensues, and when his former allies reveal their true colors, Kyle is forced to run for his life in the city where light and shadow intersect. Whose memory is he repairing? Is it evidence of the Clock Tower's ruler's ulterior crime, or is it his own buried soul?
In this war where memory is the bet, he must face the ultimate question: when your past can be tampered with, what defines your existence?
