I saw the movie of the same name for the first time eleven years ago and was deeply moved to tears by the story of Hachiko. Companionship, loyalty and love are the eternal agreement between dogs and human, and they are also the main theme of the creation of my works. In addition, I chose the format of Carousel, with the rotating pop-up books, a special artist-made book binding method. When the first chapter is connected to the last chapter, the story begins a new cycle, just like the agreement between us and our beloved pets —— We will kiss goodbye our last pet (who has already become an angel) with the love we had for them, and we will also welcome new pets with this love. In this way, the miracle of cyclical love will accompany us throughout our whole lives, over and over again, happening.
