Everyone has a "ghost" in their hearts. It is a genuine feeling that is there but inexpressible. In this work, the girl Nike opposes the absurdity of the world in order to protect the "starry sky." This challenging work expresses Nike's solitude and heroism, and the subtleties of the heart as she interacts with others.
