What has Ryouichi gotten himself into?!? This was just supposed to be an easy job. Watch over his best friend's sister while he's out of the country on business. Not only is it his friend's sister, but her three best friends as well! Now he wonders if his friend left the country just for business or to save his sanity. Each girl with a distinct personality all her own and each one needing something special from him?!? His dad always told him to stay away from high school girls...
