In an unexpected event and 80 year promise results in a arranged marriage between the prince and a peasant( grand child of a man who was a close true friend of the crown prince's grandfather) The prince begins to attend a art school, different from that of the royal academy people of higher status usually attend. It just so happens in this school is the one who is to marry him, though they don't know it quite yet.
