(Huh? She invited Shouta? What for?)
I forgot, but Yayoi doesn't seem to dislike Shouta or it's more like she wasn't there whenever he's talking about her.
First time you meet him, it was just P and Iori.
2nd time you tried to keep the two away and it sort of worked.
3rd time Yayoi was busy greeting people at the party.
So you're saying...Shouta's (sort of) bullying Yayoi?
I don't think so, it's more like he's so overconfident on his own skills that he says stuff bluntly like that, I don't think there's much hostility in his words.
So wait, Shouta thinks Yayoi's a threat, or doesn't he?
He thinks of her as a bigger threat than RK's Iori, but not as something he can't handle.
And 765pro invited 961pro? At first what comes to mind is "Are you guys DUMB?" But at the same time, the fact that Kuroi accepted such an invitation?
It's just a party organised by Yayoi, not one by the company, so I don't think it's that much of a problem.
Yayoi probably invited Shouta because they're the both the same age and idols.
