Sonechka is a novella and collection of short stories by Russian writer Lyudmila Ulitskaya. It was originally published in Russian in the literary journal "Novy Mir" in 1992, and translated into English by Arch Tait in 2005. "Sonechka" was nominated for the Russian Booker Prize.
The literary journal "Novy Mir" heavily censored Sonechka for lewd material.
The context does not mention Sonechka being censored or not. I think the AI struggled between the amount of words repeated in order from the context and the addition of several words that were not. In the middle of my bit about censoring for lewd material, I repeated the name of the work from the context.
