Betrayal Knight’s Joyful Faith Novel

Poor theater actor Lee Soo-hyun loses consciousness after being struck by a falling stage light. When he awakens, he finds himself inhabiting Arendt von Eckhart, a character from the abandoned novel "The Blue Knight of the Holy Sword," which was discontinued due to poor reception. Trapped in the body of a knight who betrayed the Knights Templar and faces imminent execution, Soo-hyun realizes his character's story has reached its conclusion—death is the only exit remaining on stage. However, an actor's interpretation can reshape a character's fate. Desperate to survive, Soo-hyun must reinvent Arendt beyond the role of mere traitor, deviating from the novel's predetermined plot. What begins as a battle for survival transforms into a dangerous method acting performance where the line between character and reality blurs, and every choice carries life-or-death consequences.
