"Is one-sentence paragraphing indeed alien to English for writing fiction?"
Not at all. Suspense thrillers (and newspapers, tabloid news stories) use one-sentence paragraphs a lot because they serve as 'attention-getters' through the dramatic impact they make. However, a string of them can defeat their own purpose of making an impact.
Used sparingly, they can be effective at making key points even in non-fiction writing.
