"Oh? They won't be coming today?" Honest curiosity. Kise's going to pose for this guy, who seemed like a loner type of person that works alone. So he's surprised to hear stuff like that.

"Ah... that's... haha, never mind." Sparkly water. Yes, he has no idea how to explain it. He catches the water bottle with one hand and nods:"Thanks. And will do." He strides over to the windows and pulls down the blinds with a hum. Now that surprise from being offered to do thing like this, has settled, he feels kind of excited.
