[That confirms it's work related, he tries not to laugh looking at Yamaguchi shrink down into his chair. Sure, he might not be as huge as some of the Karasuno members but he's not a kid, if he hid under the table bits would stick out.]
What could you have heard here to make you nervous? [He sounds puzzled and amused, as anyone would when their date is in the process of freaking out. Well, anyone who gets amused rather than concerned when people freak out, which is probably a fairly short list.
He can't imagine that Yamaguchi's stress is something he needs to worry about, they're in a restaurant he knows well and no one in here would bother him in any way, though god knows what enemies Karasuno's making these days, there could be something that is a legitimate threat to him. But Oikawa doubts it.]
