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: Except the fairies are all too naive to notice. Tense romantic/sexual situations have been instantly resolved by their realising they haven't a ruddy clue what's actually going on anyway, then getting distracted by something else entirely.
Lost in Translation: The anime relies too much in many very specific stuff about Japanese culture and it's very difficult to adapt entirely, especially in English.
Tastes Like Diabetes: Even the people who like it admit that it's literally condensed cuteness. It's been known to be used as a benchmark for loving cute things — if you can't stand it, you're a poser.
