Asili Rosé awakens in the body of the Estrian Emperor's eighth wife's daughter—a second chance at life that quickly reveals itself to be a curse. The diary she discovers contains a horrifying prophecy: Crown Prince Castor will become her executioner. Each time she tries to escape this fate, she dies by his hand, only to awaken and relive the nightmare. With every rebirth comes a deeper darkness, as hope erodes and desperation takes hold. Survival becomes her sole obsession. Among the palace's shadows emerges someone with pale sky blue hair—Amoru—whose cryptic presence hints at something beyond her understanding. When he brushes his fingers against her wrist and speaks his name, Asili realizes that escape may require more than mere survival. 'Light of Rusbella,' the melancholic romance she was reincarnated into, demands a price far steeper than she ever imagined. In a world where death is no longer the end, can she find a reason to live?
