I think I see a typo: "giving Naoyuki all the excuse her needed". And possibly another one, in case Naoyuki is the one grinning: "but she could tell she was grinning like an idiot".

And while he's anxious to get under her skirt, I'm still waiting for some serious communication with the Kami. If it ever comes to that... surely she can't resist forever, can she? Not that I blame her - it's not as if Tamao has been very subtle or delicate. He's been acting quite pushy and desperate. I wonder if he just lacks manners and/or consideration, or if he really doesn't have a lot of time?
