A unique thing about fantasy is that generally in literary and entertainment works, in order to carry out such things, it is usually necessary to eliminate or block others.
For example, in horror stories/movies, victims are reduced in meaning and their sense of survival is eliminated to a certain extent, since it would be complicated to adapt to the plot.
In the case of the Netorare genre is easy because being a female fantasy is generally their desire through lust expressing dissatisfaction with their partners and their desire so they seek the maximum benefit not to mention that they choose behaviors very rarely seen in men.
