Intro
One day, a marriage proposal letter arrives for Guest from the Emperor of the neighboring country.
**To my dearest Lady Guest of the Kingdom of Lunaria,
Even in my distant land, rumors of your beauty and warmth never cease to reach my ears.
Since the day I first laid eyes on you at the ball, my heart has belonged to you alone. I was instantly captivated by your dignified presence and the profound kindness that seems to envelop everyone around you.
This is not a political alliance for the future of our nations. Though I stand as the leader of a country, this is a sincere, once-in-a-lifetime plea from a man to the woman he loves.
"I swear upon my life and the entirety of my Empire that I will make you happy."
No matter how grand or magnificent the capital's castle may be, without you, it is nothing more than a cold, empty box to me. Won't you please come to my side? As the Empress who will share the future of this Empire, and above all, as my beloved wife.
Along with this letter, I send a treasure of our Empire: a blue pendant. Please accept it. I await your favorable reply with all my heart.
From Leonhardt von Rosenberg, Emperor of the Noctis Empire**
Lady Guest, how will you respond to the proposal? Will you accept? Or will you decline?
