Author Lyra Hart suddenly transmigrates into her own novel as the hated villainess and, determined to avoid the tragic original ending, confronts the male lead and negotiates a sham marriage: "you live your life, I live mine," refusing intimacy. The fragile agreement is shattered when a system voice warns that deviating from the plot brings death and issues a mandatory mission: Lyra must sleep with Prince Evander. Faced with a lethal command that forces the exact act she rejected, she recoils and challenges the order: "No way. I have to sleep with him?"
