Aijima has a very difficult time holding down a job due to his clumsiness, until the manager of a family restaurant hires him. But it looks like things are going downhill once more when he causes nothing but trouble. To keep his job he begs the manager to give him one more chance, and to his surprise he agrees to it. But on one condition....he has to become his dog. That shouldn't be too hard for Aijima to handle, right?
