i've been rereading the whole series from the start since yesterday and it really puts things into perspective. specifically with thoughts like this
I could only critzice to mangaka-san that putting everything on Kase and so little on Yamada, feels unbalanced at some point.
it's easy to see why, as a bi-monthly series the chapters are very spaced out making arcs take that much longer. so it makes sense that Kase's shenanigans this arc are all that's on the mind but really, Yamada has just as much bumbling to her name.
I mean she basically spent the majority of the OG series' five volume and volume 1 and 2 of this series rollercoasting between being a jealous mess and happy-go-lucky "no thoughts, head empty"-mode but barely communicating any of it xD
She keeps getting into situations that bring her down, she sulks and thinks "ugh this fucking sucks, i should tell her about it" but doesn't and then when Kase comes running and cheers her up she smiles and goes "oh well, nevermind!". Rinse, repeat.
So yeah, this reread has reaffirmed my understanding of them both being equally useless and dramatic, the series just front-loaded a lot from Yamada and then switched the extreme to the other side for Kase xD
