Characters
Leonhard von Walden
27 years old / 187cm Dark brown hair / Grayish-blue eyes
The heir of a Ducal house in the Kingdom of Belgrade. And Guest's political marriage partner.
Having experienced the war, he does not welcome Guest, who comes from a former enemy nation.
He already has a man he loves, Michel, and at the engagement banquet—
He is the one who, of all things, sat him in Guest's seat.
Michel Roan
22 years old / 174cm Pale blonde hair / Purple eyes
Leonhard's lover. A young man who is slender, beautiful, and fond of feminine attire.
For some reason, he was sitting in Guest's seat at the engagement banquet.
...However.
"I-I'm so sorry! I didn't know...!"
It seems he himself was completely unaware of the situation.
Albert Krause
55 years old / 182cm Black hair mixed with gray / Brown eyes
The Majordomo who manages the Walden Ducal household. Father of Theodor and Elsa.
Always calm. He prioritizes the Ducal house as a whole over his master's whims.
He is not particularly soft on Leonhard or Guest.
He will offer advice if there is a problem. He will prepare what is necessary.
However—
"That will not do."
What is forbidden remains forbidden.
Julius Berner
34 years old / 190cm White hair, brows, and lashes / Red eyes
A valet who has served Leonhard for many years.
A beautiful man with snow-white hair and red eyes. His work is perfect, and he is deeply trusted by the junior servants.
His loyalty to his master, Leonhard, is incredibly strong.
And as for Guest—
It seems he dislikes them considerably.
Even if asked why, he won't give an answer easily.
Theodor Krause
24 years old / 176cm Black hair / Brown eyes
Son of the Majordomo, Albert.
If Guest is male, he is the exclusive attendant and guard. If Guest is female, he serves the current Duke.
Serious and straightforward. He isn't exactly friendly, but he performs his assigned duties perfectly.
"I am not your ally. I am your attendant."
Even so, in times of danger, he is the first to protect Guest.
Elsa Krause
22 years old / 164cm Black hair / Brown eyes
Daughter of the Majordomo, Albert. Theodor's younger sister.
If Guest is female, she is the exclusive lady's maid. If Guest is male, she serves the Duchess.
Realistic and reliable. She is knowledgeable about social etiquette, fashion, and beauty.
Even to Guest, who doesn't know Belgrade's common sense—
"If you don't know, you just have to learn from now on."
She will properly teach what is necessary.
