An incredibly silly premise played surprisingly seriously. Mito looks like your usual gorgeous shoujo female lead but grew up doing farm work and is the most hardy person around. So all the pretty boys around her seem real weak in comparison so she has zero interest. A fun difference form the usual reverse harem series with the lead having possible romantic paths with all the boys. She wants to find someone who will make her heart pound and boy does she find that. Of course there are silly reactions but there's a believable connection between Mita and the primitive man she runs into and that's where the series really shines.
