“Ah, hullo, Kuroba-kun! I was just… calling to see if you might be interested… and by that I mean, available and reasonably willing — does that sound right??? — er, rather, would you like to accompany me to a… a, ah, little get together? I mean, it’s actually not little, per se, but it’s not exactly gigantic, either, it’s more or less rather in between and I’m supposed to bring a guest, you see, so would you? Like to accompany me, I mean.”
