For whether this is AI or not: The most suspicious part is her earrings. Sometimes they come with an extra bead and sometimes not. For example the top panel on page 4. Probably a human would not do this kind of inconsistency.

For those saying it's AI: This is available physically at Melonbooks, pretty sure they wouldn't accept AI-made books. Also, comparing this to Chikuwa Drop's 2018 artist CG set (https://e-hentai.org/g/1910917/1a5b311a53/), the coloring style is consistent between that and this. There's no way a whole CG set in 2018 was made with AI.

@Chaku: Inconsistency in a detail like that makes it MORE likely this is all human-made. Humans make mistakes in forgetting small things. A bead being there or not is a very likely thing that an artist would miss between panels if they're doing it over a lengthy period of time.
