There's been a lot of speculation about what Inoue-san's deal is. I don't understand why what seems to me the most obvious version hasn't been more popular.
I think Inoue-san has never been Kase-san's girlfriend and it's never even occurred to Kase-san as a possibility (in fact the longer the story goes the more I think that Kase-san has never had a girlfriend, it's just been assumed because she's so cool and princely)-- but Inoue-san wants her bad and was about the closest person to her for a long time, so she feels like Kase-san is her property. She's never had the guts to propose and sort of coasted as long as Kase-san seemed oblivious to romance and never got close to anyone in particular. She assumes that Yamada might be a junior version of the same thing, feels threatened by how much Kase-san's been talking about this new kid, but doesn't figure this mere non-athletic person for an actual girlfriend, at least not yet. So she's telling Yamada "I liked her first, I'm senior around here, she's mine, back off." In a rather snide and snippy way.
She may even have been planning to use this special occasion--this run just between the two of them--as an opportunity for confession. And now, from her point of view, there's a third wheel. Might go some way towards explaining how rude she's being.
