The existence in the work of the artist PARK Jinsung 〈Ajeossi〉 does not refer only to a middle-aged man in the dictionary sense. A being who represents an "anonymous adult" who may be someone's father, husband, or himself. The artist intended to capture the inner world of unpretentious, artless adults through the peculiar character created by adding wrinkles and a light mustache to a child’s face. The artist expresses the repressed emotions that have been built up in his heart through the image of a tearful figure, and tries to convey a message of happiness and comfort through various facial expressions and situational descriptions. He believes that real happiness comes when he lets go of adulthood for a moment and lets out of his honest self.
