God. I feel like every new shoujo pseudo european setting I pick is decreasing in quality. I've scoured the whole website, read all the "reincarnate as the villainess", and now all that's left is the dregs... where the main antagonist is so fucking childish he won't even read evidence presented to him before throwing a tantrum.
What kind of crappy worldbuilding is this, where a Duke can behave in such a way? What does that guy do all day, to be such an emotional wreck? Surely he got some lessons drilled into him as a child, and then to successfully succeed in his title? Please author san, make an effort.
