Two gods created the world. The Sun God and the Moon God. Though equal, they were so different in so many ways their people split in two. Saddened at the turmoil, the gods blessed mortals from each side, naming them as their descendants. Jisung is a descendant of the Moon, the first born Prince of the Moon lands. Minho is descended from the Sun, the only Prince of the Sun lands. Due to the threat of rising war, a marriage between one of the Moon Princesses and Prince Minho is arranged. But what happens when Minho is much more drawn to the Prince of the Moon? What happens when they grow closer and pursue what is forbidden?
