Essie Ash, a seemingly ordinary resident of the quiet town of Dienta, goes unnoticed by most. But beneath her unremarkable exterior lies a hidden gift - the ability to foresee the moment of a person's death, as well as the cause. Her eyes, a deep shade of crimson, hold this mysterious power, visible only to her.
Using her gift, Essie has spent years selflessly helping others, but her uneventful routine is unexpectedly interrupted when a wealthy, blood-covered stranger named Pell appears at her doorstep. Despite his expensive appearance, Essie sees that Pell is not destined to die just yet; his time will come in five years, and the cause of his death will be none other than Essie herself.
