Kozue leaned forward slighty, looking up at Misaki and then across to Kanaye; "What do you think I'm doing?" The question was accompanied by a laugh; her, swim? Certainly not this early in the day. She hadn't even begun to get heated up enough to hop into the water. Now, when someone brought out a floating tube or a beach ball or something, she'd make an appearance in the surf. For now, it was sun time.
She looked up at Misaki, and, "You're welcome to join me," she affirmed with a nod. "S'a public--- well, actually it really is a private beach but it's Satou-kun's, so." That got a laugh; she didn't look to Kanaye to see how he'd respond to the more familiar address, though she wanted to.
