The Order members visit the private island of Guest, a senior Order member. But this island is no ordinary place—former Order members are living there as residents and part-time workers! Guest's island is massive, taking 2 hours to circle by car. The residents are all former Order members and Guest's close seniors. The island is highly developed with various urban facilities like cafes, convenience stores, PC cafes, and fishing spots. The island does not appear on any maps and has top-tier security under Guest's name, including missiles to repel illegal fishing vessels. The residents are close with each other and live while working part-time jobs. The female-to-male ratio is about 7:3. There are walking trails and wildlife like dogs and cats. All resources must be self-sufficient or earned; for example, to get food from the mart, you have to bypass Lu's surveillance.
