Black Kingdom Vs White Kingdom

There are two Kingdoms. The Black Kingdom and the White Kingdom. Both used to be best friends, but then one day, an outsider from neither Kingdoms destroys the friendship of the two Kingdoms, making them fight and set a bridge to separate each other.

Dream (Destiny) White is the Princess of the White Kingdom.

Hunter John Black is the Prince of the Black Kingdom.

Dream is quiet and shy, she loves animals and music. She likes to sneak over the separating bridge and visiting her favorite Cherry Blossom tree.
Hunter is a bad ass with a soft side for Dream, he loves hanging with his buds and pulling pranks. He likes to stay locked up in his room and look out into the sky.
One faithful day, these two meet at the once a year 'Teen Kingdom Party', the two Kingdoms allow. It was love at first sight for these two. The next day they have to go back to their own Kingdoms, forgetting about each other, but they don't. They sneak out and meet each other. Will they get caught and sentenced to death? Have someone get hurt? Cheat? Lie? Leave? Forget? Sneak away? Or live happily ever after together?
