I Want to Read Some Cool Stories About Ruthless Revenge.

I don't want the kind where the enemy is still alive after dozens of chapters. It's annoying to watch. I want the heroine's perspective, and the heroine is not a holy mother but has brains. I don't want the kind that appears to be revenge but is actually a spoiled wife literature. Tweet relevant articles. Don't blame me for being ugly when tweeting randomly.
