Sometimes I've called Kageyama. Since his parents don't exactly come home on weekends either, you know....but he was gonna be busy today so...

[Yamaguchi cuts off mid-sentence, pales, then frantically starts backpedaling, having remembered too late exactly who he's talking to (and about).]

...Not that he's better company than you, I mean!! It's really great that you're here instead, Oikawa-san...!
