It's not that Kongshan Yiyou is a fool.
It's purely her instinctual unwillingness to think in that direction.
If it were you, living in your own world, with loving parents, playful friends, and companions in life, everything you experience makes sense.
In such a situation, would you, out of sheer boredom, think of yourself as a mere character written by some "powerful being"?
Even if some tangible evidence is placed before you, you would exert every effort to disprove it; that's human nature.
Nobody would willingly admit that they are just a fictional character crafted by someone else, unless ironclad evidence is presented before them; otherwise, she wouldn't consider this possibility.
Someone who thinks like this is not a genius, but a madman.
Of course, for Cai Ketongshen, such a situation is entirely different.
