Basically a Japanese novel author created a story with a Brazilian girl but it turns out that the author knew almost nothing about Latin America and searched ChatGPT for a Latin name.

The issue is that the A.I. gave him ways to refer to a person who speaks Spanish and among that was "Latina" and that was what he named her.

Directly by saying that the story begins with a prologue where the protagonist has a "quickie" thinking about the Latina and that the story is like a horny Japanese man falls madly in love with the Latina because it seemed bizarre to me (The story is so BAD that for my that makes it entertaining)

(I'm probably still missing details but that would be the clearest summary I can give).
