Maybe I'll full of energy to write your favorite fanfic.

He was once the most feared villain in the empire, a master of manipulation who wove chaos from the shadows. Ruthless, untouchable—until the day he was betrayed and executed by the very man he sought to control.But death is not the end.He awakens in the body of Lady Elara Valcrest, a fragile noble girl doomed to be a pawn in political games. Stripped of her former power, she is forced into an arranged marriage with none other than Cairon Everhart—the man who once killed her. He does not recognize her, but she knows him. And she will never forget.To survive, Elara must play a new game. One where deception is her only weapon, and trust is a dangerous illusion. She must outmaneuver her enemies, uncover the truth behind her execution, and reclaim the power she lost. But as she navigates the treacherous world of court intrigue, one question lingers—Was Cairon truly her greatest enemy? Or had she been blind to an even greater threat?Time is running out. The villain has been given one last chance. And this time, she refuses to lose.

To exist in a certain place, at a certain time—it's always either by chance, or by choice.But sometimes,There is a third force.One that doesn't ask.One that doesn't explain.It simply places you—wherever it wants.Arséne had always been dragged into places he never chose.Situations he never asked for.Realities he never belonged to.And when, at last, he decided to act on his own terms—To take the initiative,To move first,To choose…He simply died.
