How will we face our hometown again as we grow up? Everyone has been pushed to the other side of the world, seemingly suspended above the land. Is our understanding of our hometown misplaced? Or is it our thoughts that are out of sync with those of the previous generation? Can their nostalgia for the past be understood? When we look back, do we develop an emotional attachment to a space in our memories? Can we reconstruct a space from the past using words, based on a photograph or an object? This work is based on the experiences of eight people who have migrated and settled in new cities. Like "nomads," they connect their past and present lives through memories. When the tide rises on the beach, everything, including memories, will be submerged, leaving no trace.
