This is the kind of mind-blowingly dumb story that stories like QT Cannon Fodder's record make fun of as they hop into different worlds. Lol.
I immediately thought of this one as I was reading it a while ago, and the mc was one of the ugly cannon fodder women - it was about what happened to them as all of the men in every tribe abandoned their tribes, went crazy and started chasing the "only pretty girl in the world".
The author has some bad insecurity issues and it's quite evident here as she lives out her sad dream...
