I lost my parents in childhood, and died from overwork — all because of the rotten adults around me. Then, when I opened my eyes again, I had possessed a character inside a novel. Of all people — a spy belonging to a family notorious for its cruelty, an extra who dies before the protagonist even appears. The mission assigned to me: become the fake daughter of the novel’s main villain, Duke Crost. “I can’t die again just following other people’s orders.” But I know this novel’s story inside and out, so— “I’ll betray Duke Poz and side with Duke Crost!” “I’ll find Duke Crost’s lost family and stop him from ever becoming a villain.” “And I’ll ask him to find me an ally who can protect me from Duke Poz.” Of course, flipping the original story won’t be easy by any means— But in this life, no matter what it takes, I will find happiness!
