In addition to all the "marriage" overtones, there're several quotable points in this chapter.
Page 1:
Shiori: We often have to relocate back then, so I told her to keep as little stuff as possible.
This is the manga's confirmation that the Manaka household moves frequently. I think the anime make this clearer?
This is the beginning of a trend of Ao wearing twintails less often after moving to Mira's house. Personally, I think she looks fine either way, as long as she doesn't cut it to Mira's length.
Page 2:
Mira: [Misa]'d calculate stuff while asleep, or grin when spotting prime numbers...
Ao: Somehow it doesn't seem very surprising...
What is she, a math nerd?
Page 4:
Imagination! Mira: The book I found in your room was a fun read! Is there more~?
What Mira holds is a copy of
The Hitchhiker's Guide to the Galaxy. I can suppose, then, that Ao
reads SciFi...?
Page 6 & 8:
It's rather funny comparing this and Chapter 7:
[ol]
[*] Mira and Misa are both plucky and don't want others' assistance towards their goals, it turns out.
[*] Mira starts of utterly incapable in physics, and now she seems to get a grip in it. So she
does study.
[/ol]
Also, why I have the feeling that the authors are cramming masculine attributes to Ao, who otherwise is no longer a tomboy?
