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.
YMMV: Eve No Jikan
Awesome Music: I have a dream, the ending song of the movie.
Fridge Brilliance: Rikuo and Masaki are continuously subverting the cafe's main rule. Then again, that's what pretty much all of Asimov's robot stories were about as well.
Chie does not recognize Rikuo's glasses as being glasses. Yet her guardian wears a pair.
Conversations in normal tones somehow don't carry past the intended recipient, even in a small space without any apparent soundproofing.
If androids really are intended to be just appliances, it would make little sense to equip them to eat, drink, blush and cry. The former two might be acceptable, if their services include cooking, but the latter are exclusively emotional expressions.
It is implied that no two robots look alike, which would be useful for quick recognition by their owners, but inefficient for mass production.
Tear Jerker: Katoran's story and the last episode are the most significant ones. The movie implies that Nagi's backstory might be the worst of all.
The Woobie: Rikuo witnessed a robot playing the piano and was moved by it. He subsequently fell into a depression, because he was beginning to feel like his efforts were worthless.
Woobie Species: Robots. The ones seen so far have been, if anything, more likeable than the humans (to be fair, only a small portion of the cast is indisputably human). And yet they're completely unable to express themselves, for fear of being hated and abandoned by their masters.
