"Dropped it by accident," she sighed rubbing the back of her neck. It was so embarrassing to be twenty years only and still lose her own jacket. But this guy, or whatever he was, seemed to really like it. So of course her big sister attitude took over. "But if you give me my keys in the left pocket you can keep it. I got another at home I like better anyways."
He hardly payed attention to her excuses (he didn't really care, and he was focusing on his new find), but when he heard the words 'keep it' come out of her mouth his head snapped up. Those were only ever positive words.
He managed, after a minute, to slip his hand into the jacket pocket and retrieve her keys. It was likely that Shinohara would be angry with him for taking her things later, but Juuzou was willing to deal with that. After all, it was kind of a gift now. He approached her and held out the keys. "Here you go, miss! Aren't you glad I didn't just leave with these?"
