Oh? Villainess manga from the perspective of the villainess and posse? Ideally the MC isn't isekaied either? The reality is in these "reverse harem" endings they're by far the most damaging to everyone involved. First off only 1 man will become the husband, second all these other men who had fiancees are basically just cheaters, and the repurcussions for their slights against other noble families will be devastating.
Most stories don't explore this part enough, and I hope this one does. I want to see the damage the woman who seduces numerous men engaged men causes.
