There Will Always Be Protagonists With Delusions of Starting a Harem - The usual stuff with World Hopping trope where the system will give you the outline of what happened, what will happened and what you must do..... Yeah, this one is not like that. MC is given a set of information on the plot of a world, but when he actually experience it the information is all wrong. It's so twisted that even the system doesn't know the truth in the worlds. So it's up to MC to uncover the real plot, and prevent the protagonists from creating a Harem. Why? Because those harem will cause the end of the world.
