Saigo ni Hitotsu dake Onegai Shite mo Yoroshii Deshou ka (May I Ask for Just One Last Thing?) follows Scarlet, a noblewoman condemned to death after being falsely accused of betraying her fiancé, the crown prince. On the execution platform, she calmly makes a final request—only to reveal a terrifying hidden power that overturns the fate planned for her. Far from the meek and pitiful figure others believed her to be, Scarlet proves herself to be cunning, strong, and unafraid to strike back against those who wronged her. What begins as a tale of revenge and reclamation soon grows into a thrilling mix of court intrigue, romance, and empowerment, as Scarlet redefines her life on her own terms.
