Villain at the Start: I Think You're All Playing Me

I transmigrated into a novel—as the villain. The plot? A classic "young master descends the mountain" power fantasy. Simple enough: follow the script, survive, go home. Except nobody's sticking to their lines. The heroine who should fear me is flirting. The protagonist who should challenge me is avoiding me. Even the side characters are acting suspicious. Wait… are they ALL aware this is a novel? Am I the only one who doesn't know the real game being played?
