@4stjack I think it's a byproduct of the class-structured Japanese society that excels in producing "worker ants." So when they want the MC to be an everyman, they fall back to this generic beta who is lost without a command structure to direct him, easily yields to anyone that's strong-willed, and apologizes at the drop of a hat. They hesitate at every decision, don't want to make waves, and their biggest wish is to simply have a chance to relax without societal pressure.
But as someone outside of that culture, it's hard for me to relate to that mentality, and I get irritated that it's so prevalent in manga.
This MC in particular has been living in his castle for a couple months already, and is just now taking the time to figure out all of its functions. Plus, I don't understand why he can't just tell the others, "I woke up in this castle one day, and the golems obey my commands, but I'm not a magician and I don't know how this all works."
