Platinum Love
In this dystopian city of Arkana, two young kids—a young rich girl and her best friend, an orphan poor boy who lives in the slums—are suddenly separated when the government of Arkana decides that enough is enough and puts a wall between the rich and poor. They both made a promise to each other that when the time came, they would both look for each other again, and 15 years later, that time finally came when the wall was suddenly brought down.
