I transmigrated into a book and became a cannon-fodder villain destined for a miserable end. Knowing exactly how the plot was supposed to go, all I wanted was to stay away from the protagonist and quietly make it to the ending. But the protagonist kept getting entangled with me, and I was constantly triggering death flags. I proceeded cautiously, planning every step and focusing on saving myself. I never expected to derail the plot by accident and live out a completely different life as a villain.
