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.

Are There Any Cool Stories About Revenge, Not the Kind Where You Just Kill Whenever You Want?
