Uzumaki, Happiness Recommendations
While Happiness leans further into drama than Uzumaki, I think the two works have a number of similarities. The things that stood out for me the most were the atmosphere and the pacing/delivery of the horror elements. Both stories had a very measured, deliberate delivery of the high impact horror moments. This creates a feeling of apprehension as the reader begins to understand and anticipate how the darker elements of the story will manifest themselves.
I think people who enjoyed the aforementioned aspects in Happiness will be able to appreciate Uzumaki.
