He could try to recommend the book "Wear It Quickly: After Binding, the Villain Begs for Kisses Every Night." Although it was a sci-fi space-time travel novel, its plot did include intimate scenes of dialogue. After the protagonist Shi Lian mistakenly kidnapped the quest target, he was pestered by the sickly villain. The conversation and intimate actions between the two of them were quite sweet. I hope you like this fairy's recommendation. Muah ~😗
