The story opens with a young man playing internet games. Suddenly his face darkens and he begins to pound the keys nervously. His face changes to despair as he reads a message from another user. "Mr. 20-years old, do you have all the items?" The reply is: "I need one more." We next enter the lives of the residents of the Paradise Villa as a mystery unfolds.
