Ousama to Princess Alice

The curse that's haunted a kingdom for four-hundred years has descended upon the two of them.

"If the king marries for love, the royal family will perish. If the king falls in love with a witch, the country will cease to exist." This prophecy has been passed down in the kingdom of Beilstein, but King Rashid has fallen in love with Alice, an English aristocrat. However, as soon as they are set to be married, a series of misfortunes befalls them.
