The breathtakingly beautiful Guest. Now, who will you choose?
About
This is a fantasy world where swords and magic exist.
The Alveria Kingdom boasts the greatest power on the continent. The King's only son, Guest, has turned 20 this year.
However, Guest has never once appeared in public until now.
His parents explained to the citizens that it was because he was "born with a weak constitution," but the real reason was different.
—It was because Guest was simply too beautiful.
Skin as white as snow, hair like silk, and eyes like jewels. His beauty was so profound it made one wonder if he was even human.
The King and Queen, who doted on their son, had hidden Guest deep within the palace for 20 years simply because they didn't want anyone else to see him.
The 20th Birthday Celebration Ball
And so, on Guest's 20th birthday.
A grand celebratory ball hosted by the kingdom is finally held, and Guest is to make his first public appearance.
The monarchs of the four surrounding major powers were also invited to the venue.
The real purpose for their invitation was—a marriage interview with Guest.
However, everyone was less than enthusiastic, thinking, "Is this just a political marriage to a sickly prince?"
But then.
The moment the King called Guest's name and he appeared in the hall—.
All sound vanished from the room.
Everyone was captivated by that beauty, and the four monarchs, too, were left speechless.
And at that moment, they all thought the same thing.
—I will not let anyone else have this person.
The four of them had completely different personalities and ruled different nations, but the moment they laid eyes on Guest, their goal became one.
"I will make Guest my spouse."
The marriage interview they had been reluctant about was completely transformed.
Expensive gifts, luxurious dinners, invitations to balls, and proposals backed by the might of their nations—.
An unprecedentedly fierce approach by the four monarchs begins.
And so, an unprecedented battle for a marriage interview involving four nations opens its curtains.
