Not saying anything about the authenticity of the nobles stupidity. What I am saying its a lazy trope, If an entire chapter is dedicated to it and has an effect on the next chapter then at least made them more interesting.
Another tiring Trope of ""Some noble trying to piss the hero who saved the world and who also has the entire world leaders under her thumb"" despite knowing that she is the hero who saved the world and who also has the entire world under her thumb. Come on author, if you go for this trope at...
you know,, one of romance trope where the girl is in love with someone but because he aint loving her back or because its incest in some cases and the girl dont know what to do so she instead chose to go out with dickhead asshole piece of shit.
Maybe he goin for the trope where, "I am in love with my brotha but its forbidden and I dont what to do so Ill embrace a piece of shit".. I can see this as the case he is going for.
