An Extra Who Wants to Escape The Obsessive Male Lead

I am a fake bride. The name of Diello Argenta engraved on my back, the name that indicates that I am his destined partner, is also fake. Right now, I am possessed as a villainess in a 19+ novel that is set up like a gambler. How can I survive like this? It is a contract marriage! I will pretend to be his wife until the real one appears, pretend to seduce him, and protect his chastity, and when the Duke of Argenta awakens his power, he will destroy my villain family. In that way, I became a contract couple with the innocent Diello Argenta and “acted” a sweet newlywed life day and night, “If your real partner has appeared, it is time to fulfill the contract.” Diello, the Duke of Argenta who had been staring at me, slowly opened his mouth. “When Pero dies, a new Pero will be assigned.” His hand raised the tip of my chin. Our eyes met very close together. “I am confident that I will try until it becomes you.” What about you? He was starting to become obsessed with me. But weren’t you a pure and affectionate man?
