But as story goes on. To keep protagonist clueless, author will make protagonist(supposely average normal person) act like brain dead patient(strange grief is a good example).
I really hope you would not do that to sage khun. Just give him more awareness but keep that sage's wisdom(lol) going.
What I mean is. After misunderstanding build up over each other, there will be a point that you must choose between let him acknowledged reality or keep him cluelessness at same level(but make him look like mental challenging patient).
I hope you choose former choice.
And yes it happened to nearly all misunderstanding novels I read(around c50-c200 depend on words length and author's ability).
