A few things I don't see mentioned:
It was nice to see someone who could wrap Yugami in their pace for once; his "foil" so to speak. Suzune is actually kind of cute in her own way =03.
Second, I respect the fact that even though Yugami calling Chihiro for a private talk LOOKED like you're typical confession deal, but neither acted, nor did the story imply that any type of romance was going to happen(hesistant *glups*, blushing, internal thoughts, etc.). The scene was just as normal as could be.
Lastly, I really liked that the dad practically s--ted on the general trope of underage kids living at home(or apartment, etc) by themselves that we see in a crapton of manga =03. Although I say this, I don't actually know if that's a common/rare/exceedingly rare thing in Japan.
