After chasing a mysterious girl in white, a man with no memory takes the name Lumen—the only clue etched on a pocket watch he must repay to a craftsman. As fragments of his past surface and the craftsman abruptly closes his shop for urgent business, Lumen’s fragile new life unravels. Reluctantly, he takes on a risky job that drags him deeper into secrets and hidden motives. He plunges into a dangerous conflict between rebels and mercenaries, where he is captured and taken to a shadowy realm where nothing is as it seems. Haunted by buried emotions and flickering flashbacks, Lumen’s understanding of himself is challenged. Caught between external threats and inner turmoil, he must decide what kind of man to be. A cryptic warning emerges: true freedom demands facing one’s past. But as Lumen’s memories threaten to shatter the life he’s built, the line between truth and illusion blurs. His quest for self-discovery is just beginning, and the path ahead is darker than he ever imagined.
