I'm not really sure. It could refer to a specific set of rules or instructions related to a particular yu manhwa. Maybe it's some kind of hidden message or code within the story.
I have no definite idea. 'The code of yu manhwa' could potentially be a code used for access or interpretation of the yu manhwa's deeper themes or hidden plot elements. It's quite ambiguous without more context.
Yu's ancient meaning referred to "I" or "surplus", such as "once gave me a nuclear boat" in "The Story of a Nuclear Boat". Now the meaning refers to "surplus" or "redundant", such as "the rest is not enough to view it" in the Analects of Confucius.
