I Shall Master This Family - Vol. 1 Ch. 14

This chapter has secured the grandpa as also being incompetent. I had my doubts about their “education“ system before, but the fact that it was so blatantly obvious that the person who won the dumb heir competition in the end was useless while everyone else had at least basic competence despite grandpa personally reviewing everything tells me he is just as much to blame for the downfall of the house by incompetence as anyone else.
This whole family needs a complete reform to deal with them keeping anyone with a brain away from administrative roles. I feel as if all of the adults in this story are examples of falling upwards.
