'KIM SAEHYUN' is a series of photography about my nephew who became my best friend from the moment he was born. Although he is my best friend, there will be a gap between his and mine memories, differences in values will arise, and eventually we will grow up to be individual and mysterious human beings. Perhaps that path is the relationship between a child and an adult. This work shows the failure of one person to fully understand the other through the ontological uncertainty of photography.
