<Night Worker> shows the boring everyday duty of a night security guard of a building and a toll collecting woman at a toll gate.  As the two characters step outside after finishing their work, the sunshine which was absent all night pours down on them, and the awakening that they lacked suddenly turns to the point of excessiveness. My main conceptual interests lie beyond the limitations of formality, in the psychological space of people in their own environment.  Rather than intervening with my own strong interpretation, I carefully displays what I have observed.
