Here I was saying Sei is a hardliner XD.
Sincerely... despite finding it beautiful the act of inheriting a business, the way I see it depicted in manga and other Asian media is... dangerously constricting.
Sure, part of it is fiction, but themes are popular in cultures for a reason.
Some businesses and some families will deal with it in a good way, but some others thread a dangerous line where they treat the new generation as a foregone conclusion that they WILL inherit it, and whatever they think or desire for themselves is just immaturity.
But mind you, I am overly simplifying a feeling that translates to something much more complicated in real life.
