@cannelloni She was, he was just too dense or too preoccupied to notice. That's part of the problem. Again, because it's just the "nobles" that notice and try to correct it, while the protagonist coddles, any improvement will feel artificial and forced. And I fear this will just be the start of the usual forced harem bullshit of isekai. Which I was enjoying not having to deal with so far.
that is not how you teach, thats just adults too lazy to assume proper responsibility and command, to teach is to tell so she knows where she's worng and whats right, and to show with action why shes wrong, not dumping her at the sidewalk just because she doesnt know the way, thats how she became rotting corpse by the alleyway, while miyabi is dense but he's doing it the right way, he told her she done it to her way and ability but its not enough "she" can grow to be better to overcome this failure.
i already saw it that duke, only define people by useful and not useful, he didnt very try to make them be useful, like with how miyabi wants to make railway in the end miyabi himself that made that idea useful, the duke didnt even try to consider how that railway might beuseful for him and the teritory. just utterly.....
