Why are people saying it's the 4th wall when nowhere in the novel it's implied that it's the 4th wall? There is actually a part where they hinted on why his face is blurred but it got ignored coz people already tunnel visioned on 4th wall.
Some novel readers just theorized that it is 4th wall early in the novel coz there's still no explanation, and it stuck until the end. They tunnel visioned on it so much that they ignored some indications debunking the 4th wall theory.

SPOILERS....
The 4th wall weakened/turned off completely many times but the blur is still there. Some readers actually questioned if the blur will disappear coz 4th wall turned off, but later they got shocked/confused coz the blur is still there. Even the characters themselves didn't react to Dokja's face after the 4th wall turned off. This got ignored coz people still zeroed in on 4th wall.
Another thing that got ignored is the clear hint at the end on why Dokja's face was blurred. Han suyeong and the others want to exact revenge on Dokja so they decided to write him as ugly when they're making the novel. Given the novel's theme, they wrote him as ugly so the universe/starstream/whatever censored Dokja's face.
That is the only time that the novel acknowledged and hinted about Dokja's censored face. It is at the end but some readers already focused on 4th wall by tht time so it got glossed over.
