The Protagonist Who Became the Villainess

He was destined to be the villainous Demon Lord—fated to die and fuel the romance between the story's golden couple. But when a protagonist from another dimension kicks him out of his own narrative, does he accept defeat? Hell no. Instead, he takes the original leads hostage with a simple threat: "Abandon me, and I'll destroy them both." Now the former villain must carve out his own destiny in a world that never meant for him to survive. A twisted cultivation tale where the lines between hero and villain blur beyond recognition.
