Kwon Jaehwan opened his eyes in an unfamiliar world, only to realize that he had been reincarnated.

However, he had not reincarnated in any ordinary novel but inside a psychological mystery novel, Ashes of Vengeance. Whose naive and kind protagonist, Theodore Granville, loses everything he loves in an arson staged by the Earl and falls into insanity.

His madness drives him to get revenge on the culprit and destroys him.

Unfortunately for detective Kwon Jaehwan, he was reborn as Arthur Ashbourne. The same Earl's only heir who is destined to die before the story even begins.

However, Jaehwan has no intention of letting the story keep its course and intends to live a long life instead. With the knowledge of the novel from his previous life and the wealth from his current one, he plans to protect himself while also saving the characters from their tragic ends.

But what happens when his father, the story's central antagonist, disappears during a sea expedition?
