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.

YMMV: The Cat Returns
Alternate Character Interpretation: In the fandom: Louise or the Baroness, a very minor character with only one shot and no lines during Nishi's telling of Baron's past in Whisper of the Heart, has become a fan favorite, with personalities ranging from evil, rival love interest with Haru for Baron, to sweet and kind rival to even Haru or Baron's sister in some fics. If she was a person, she'd either be totally insane or have Gollum-level split personality disorder.
Also the Cat King, ranging from slightly senile old man(cat?) to psychotic, so obsessive over wanting Haru for his own he'll kill to do so.
Ambiguously Gay: Natori's care for the King seem to go beyond simply duty. He immediately express concern whenever the King hurts himself or gets upset, gets an offended look when Muta refers to him in a mocking manner, and the camera cuts to him alone having a shocked reaction when the King asks Haru to marry him instead. Also when the King decides to retire, Natori immediately concludes that he'll be retiring too in such case.
