What do you get when you take a plot about an arranged marriage between a 16 year-old girl and a 37 year-old man in Feudal Japan, and throw in some supernatural elements, as well as strict rules of engagement? You get 'Ne Ne Ne', a story that somehow manages to make these elements come together in an endearing, natural way. Nothing about the age difference seems forced despite the concept sounding problematic; it's handled in a light-hearted, innocent way, as both mains are very pure. It's a short pilot, but 'Ne Ne Ne' is worth the read as it's in the process of being adapted
into a full series. Give it a chance if you're a fan of historical fiction and/or age differences.
