Yuki laughed along.  Truth be told, she was fun to laugh with.  Some people would take such things seriously and say things like 'I'LL NEVER FORGIVE YOU IF YOU GO BACK ON YOUR PROMISE!'<br/><br/>Thankfully, he was sure that one girl (whose name he had forgotten, of course) in the Village forgot about that marriage promise he made when he was six.  It wasn't his fault he had not yet learned by then about the most insidious weapon in the female arsenal: the sad eyes.  Any female could use them, and they did not rely on sex appeal or any sort of superiority.  Even non-kunoichi could use the sad eyes to great effect, and they could absolutely destroy lives.<br/><br/>When she asked<em>that</em>question, he took a second before answering.<br/><br/>"We are involved in undertaking missions along with our teammate and Sensei," he replies.  He had seen both of them in states of undress before, but that had far more to do with performing medical treatments than anything else.  Sure, they had experimented a few times, but treating juvenile pawing and messing around as 'being involved' was foolhardy.  However, if he was honest, he would have to admit that despite the literal barrier surrounding Makoto had done less to dissuade him than one would think.  Kotone wasn't unappealing either, though.<br/><br/>If either called him into their bedchamber at night, he'd find it hard to refuse.<br/><br/>He smirked.  "Of course, you knew that already.  You're 'involved' with your teammates, too, right?"<br/><br/>He knew when he was being baited, even if it was just teasingly.
