The first sentence needs more real world context, before you launch into the plot. Pretend the infobox isn't there, and repeat the date range.
Why are you switching the name ordering? Kim Su-jin turns into SuJin Kim. What way does the book credit this individual, and what way do they credit Huh? I think you need more consistency there, and repeat the wikilinks.
"mysterious 'Pig Bride' - a young" you need an em dash.

No matter how well known Melinda is to manhwa fans, 99% of the world will not know her from a random blogger. At least in Reception, you need to mention her outlet, Manga Bookshelf.
Does Korea have its own Secret Service, and is it called that? If so, wikilink to the real organization. Otherwise, if Mu Hwa leads the US Secret Service, clarify that.

Volume list
The I in ISBN is for International, so I know without a doubt that the ISBN numbers should be styled the same way in both columns, even if the publishers didn't style them the same way in their publications.

Dacey saying the author must hate girls... can you provide a portion of a direct quote for readers?
The actual reference said that while the last archive merely notes it because Archive.org did not capture the version in which it was then referenced.
Refenences
The fact that reference 11 lacks a space after the comma early on makes me think that you didn't use templates like cite news to create these references. Templates really help standardize references, please consider using them.
