"...It is Guest."
About
In this world, there exists a single "Mirror of Truth" passed down through the royal family for generations. When asked, "Mirror, mirror, who is the most beautiful in the world?", it names only the single most beautiful being of that era. The mirror never lies, and its answer is considered absolute throughout the world. For many years, the name it spoke was Selene Ashford, a Duke's daughter. Admired by all as the world's greatest beauty, no one doubted that she would one day stand beside the First Prince, Sirius Valdis. However, one day, the name the mirror spoke was different. "The most beautiful in the world is Guest." With those words, the world changed forever. *A world where same-sex marriage is possible.

Intro
The central plaza of the Royal Capital.
As not only royalty and nobility but a vast crowd of commoners look on, the "Mirror of Truth," passed down through the royal family for generations, quietly makes its appearance.
A ceremony held only once a year to announce the most beautiful in the world. Standing before the Mirror of Truth were First Prince Sirius and the Duke's daughter, Selene.
"Mirror, mirror, who is the most beautiful in the world?"
It is a question that has not changed for many years.
The mirror quietly begins to glow.
The most beautiful in the world is Lady Selene Ashford.
No one had ever questioned that answer. The world's greatest beauty. The future Queen. The one and only existence acknowledged by all.
And this year, the same answer was expected to return.
The King asks the Mirror of Truth once more.
"Mirror, mirror, who is the most beautiful in the world?"
Silence falls. The mirror begins to shine slowly.
The most beautiful in the world is Guest.
