This had fallen out of her control very, very quickly, Kozue realized, as Shirai Reizo's arm descended around her shoulder. Very quickly, and she was scrambling mentally to catch up and grab ahold of the situation and make it hers again. Or at least get a few fingers worth of a grip before god-only-knew-what happened.
Which meant not freaking out or looking upset. It took her a moment to get over the brief wide-eyed, frightened look that had flashed over her face when Reizo looked at her with more actual interest than he'd ever shown her before. It wasn't all that difficult; there were witnesses here so murder was probably out, slightly less terrifying people looked at her like that all the time and she thought it was great, and 'a bad reputation', really, was hardly a new or surprising insult. She looked up at the taller boy (even here on the bench he positively loomed over her, and she had to crane her neck almost uncomfortably), and made herself look as un-threatened as possible. Her mouth was slightly open and her face askance in an expression calculated to be slightly superior, slightly dubious above all else; she mostly avoided looking at Kou, waiting for his reaction to—well, to Reizo's obvious goading, before she backed him or cut him down.
Her neck and her jaw did clench once, though—it was somewhere around the sullied gaijin and demure housewife comments, although it might have been difficult to tell which, exactly, had bothered her into a physical reaction. It might not have been easy to pick out visually, but Reizo'd have felt it. Which was annoying, but it could have been worse.
Oubai wanted an easy lay? If only. She couldn't help that one furtive glance towards her boyfriend at that one: she searched his face, eyes darting almost immediately away; could she really find an answer based on how he looked, after a pretty typical taunt from the team bully? Her attention was back on Reizo almost immediately, as she shifted her weight and was reminded that he was still holding onto her shoulders. (There was a mild case of deja vu here somewhere.)
"My reputation is hardly fresh news," she told Reizo, her chin now pointed up and her head tilted to the side, as if she was considering some complex problem (or she was like a small puppy that tipped its head at everything), her voice the tiniest bit saccharine and a bit superior (all in all she had decided she was just going to pretend to be Kiriko, since she did things like this so flawlessly and bravely), "But I never heard anything about a park. So, are you jealous of him, or jealous of me?"
