Hmm, the title "sexy little things" reminds me of something ayu said during Arena Tour 2005 MC.
A fan asked the question "what do you find attractive in men?" and her answer was "when they are doing reverse parking, and they turn their head around and place one hand around the front passenger seat".
I'm guessing that maybe the song will be about things like this, small actions/characteristics that she finds sexy??
anticipating!!...
