Apocalypse: The Villain Refuses to Live Off the Protagonist

One month before the world ends, I accidentally steal the heroine's golden-finger system—and suddenly face an impossible choice. Obviously, I pick the path that makes sense! But future me is screaming regrets across time. Now I'm stuck navigating an apocalypse where the protagonist won't stop trying to feed me, allies keep making dramatic sacrifices, and betrayal lurks around every corner. All I wanted was to survive on my own terms, not become someone's tragic redemption arc.
