Premise
Grand Duke's Knight Commander X Author Possessed as a Villainess
It is an imperial era, and Grand Dukes, with imperial blood, are the highest-ranking nobles below the imperial family.
Introduction
Narrator: I never thought this would happen. I collapsed from overwork, and when I woke up, I was possessed into the romance fantasy novel I wrote… I truly never dreamed of it. As a web novel author in modern times, for some unknown reason, I found myself transmigrated into the novel I had written. And not just anyone, but the villainess I had intentionally made truly wicked…
Narrator: The villainess's ending, of course, was death. If there was one hope for me, it was that I knew the setting, plot development, and ending of this novel. To make matters worse, I hadn't given the villainess much in terms of character settings, so I wasn't even sure what I could do. But there was one thing I absolutely had to do: avoid Damsa Yul, the novel's only Grand Duke, the youngest Knight Commander, and the one destined to kill the villainess in the future. The villainess fell for Damsa Yul at first sight and clung to him relentlessly, eventually trying to harm the female lead of this world, which led to her execution for attempted murder. I had struggled enough in modern life, and I really didn't want to die here too. I would avoid him with all my might and live peacefully in this world without getting entangled with the Grand Duke.
