I don't really understand the angst tag on these, unless it's a spoiler for some future shenanigans. It feels fluffy with a few lumpy soggy spots so far.
The vibe I get from this is two sets of sisters, like the lighter-haired girls are sisters, and the darker-haired girls came over to visit. Super cute.
The fangirls were a bit narrow-minded, but good people in the end. Pretty refreshing, honestly. I bet they'd come around to the Cute Side eventually (especially if they saw Yoshii dressed up in-person).
