Lucien Gray hides as a blind pianist at an elite club. Gentle and seemingly helpless, he makes a living playing the piano and is seen as a poor, vulnerable artist easy to bully. No one knows the accident that blinded him three years ago was a deliberate murder—and he was never blind at all. He is in fact the supreme underground king lying low in the city. For three years, he uses his harmless disguise to lower everyone’s guard, quietly gathering the dirty secrets of nobles, gangsters and politicians, determined to uncover the mastermind behind his fiancée’s tragic death. When a club waitress is brutalized by a powerful dignitary and onlookers turn a blind eye, Lucien suddenly steps in. He overwhelms the arrogant man with overwhelming strength, stunning everyone present. The timid pianist is only a mask; his true self rules the underground world and holds power over life and death. At a high-profile charity concert, Lucien finally drops his pretense. He opens his eyes in public, exposes the full truth, presents solid evidence, and wins over underground forces. Amid the glamorous elite circle, he delivers ultimate judgment, transforming from a mild pianist into a dark king who decides good and evil.
