This work begins with the question: If there were a Pandora’s box hidden within our inner world, what emotions would be concealed inside? It explores the emotions that do not surface in external expressions, the subtle and perhaps dark feelings that people hide away in their own Pandora’s boxes. Based on the image of people carrying these hidden emotions, the piece depicts Muumyung opening Pandora’s box. What kind of inner world will both Muumyung and humans encounter as they face what lies within?
