Ryoichi's training period at work is ending. Sayo's sexual "game" with him won't last forever, so when he suggests they take a day trip together, she reluctantly agrees.

Will she learn more about this guarded man and the string of lovers he left behind, or will they be too busy steaming up the windows of his car?
