These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Les Yay - Not only does the female viewpoint character in Yui's episode play what would traditionally be a romantic role (she is rescued from thugs by Yui, and the more cynical nameless woman becomes affected by Yui's boundless optimism), she ends up holding hands with Yui while they're watching a meteor shower in the eye of a hurricane. (It Makes Sense in Context.)
