A feud takes place between two kingdoms

Everyone was told to hate each other,

but no one knows why...

Only the Kings from each kingdom do.

Love was forbidden among the two kingdoms

No one from the Kwon Kingdom could dare to fall in love with someone from the Lee Kingdom,

and No one from the Lee Kingdom could fall in love with someone from the Kwon Kingdom.

One day in the Lee Kingdom,

a baby boy was born

On that same day in the Kwon Kingdom,

a baby girl was born

Both children grew up in their own kingdom,

having everyone cherish and truly treasure them

The baby boy grew up to be a very handsome, brave prince.

The baby girl grew up to be a very beautiful, clever princess.

Both were very skilled in fighting

One day, hate brought love into the two Kingdoms

What will happen when the two Kingdoms find out about this?

Will this end the feud or lead into death?

This is the story of Prince Donghae and his Princess Yuri...
