Amorina is known as the "city on the tide." Waves lap at its shoreline to the sounds of gulls, and deep canals run through the streets. It has been nearly two years since Cello Aufiero and her mother moved to Amorina, yet despite the city's charm, Cello has yet to begin to feel at home. Like a tourist, it seems there is no place for her, and it's hard to make friends when you are only passing through.
One day, her teacher assigns the class a project, based on one simple question: "What is the true spirit of Amorina?" It's a simple question indeed, but it feels impossible for an eternal tourist like Cello. Luckily, a pair of classmates comes to her rescue. Through this simple assignment, can she find true companionship? Or better yet, her true home?
