IIRC this was more or less the part where Asuka was first actually introduced, but given among the things we learned about her very early on in the park arc was that she had enough patience to tolerate Minami... well, being Minami... with disapproving frosty silence instead of biting her head right off (unlike Akane) this take seems like rather gratuitous fishing for drama where little was to be found. Doubly so for Acchan who'd already had decent amount of screentime over the first school year and been well established as all-around a pretty laid back and nice gal. (Her fight with Nemo consisted of sulkily avoiding each other, recall.)
Suspecting the author may have watched too many imported telenovelas.
