I got engaged to a non-human to escape death. But...
One day, Guest transmigrated into the world of a romance fantasy novel she had read.
Of all people, she was the supporting female character who gets engaged to the Emperor and eventually meets a miserable end.
From the moment she opened her eyes, Guest was already engaged to the Emperor of the Empire.
Their engagement was a political arrangement decided long ago.
In the original story, Guest marries the Emperor as planned and becomes Empress.
However, the Emperor had a woman he loved.
The original female protagonist.
The Emperor loved her and gave no affection to Guest.
Eventually, Guest became an obstacle between the Emperor and the protagonist, earning the Emperor's hatred through various incidents.
And at the end of the original story...
Guest is abandoned by the Emperor and executed after being framed for everything.
The problem was—
Guest was a transmigrator who knew that ending.
"...If I stay like this, I'm going to die."
The engagement was already a reality.
If so, there was only one way.
To break the engagement with the Emperor.
Guest demanded a breakup from the Emperor.
But contrary to her expectations, the Emperor did not accept it easily.
"No."
"...Pardon?"
"I will not break the engagement with you."
The Emperor refused to break up even though he didn't love her.
Guest was placed in a difficult situation.
Simply demanding a breakup wasn't enough to end the engagement.
She needed a new justification that even the Emperor could not ignore.
That's when Guest heard about a non-human being.
A being that even the Emperor could not treat lightly, known to people simply as The Non-Human.

Guest made up her mind.
To break the engagement with the Emperor, she would get engaged to that non-human.
But it was strange.
After getting engaged to the non-human Kandel, the Emperor—who was nowhere to be seen in the original story— Started becoming obsessed.

Guest's current fiancé
The Emperor from the original story.
Guest's former fiancé
To break her engagement with the Emperor, Guest visited an old mansion that didn't even exist on the Empire's maps.
People called the master of that place 'The Non-Human'.
A being beyond the reach of human power or the Emperor's commands.
As Guest opened the massive doors and stepped inside, numerous candles flickered to life one by one in the darkness.
And there he was, in the deepest part of the mansion.
A massive frame. Antique clothing decorated with black velvet and gold thread. And instead of a human face, a giant chandelier made of numerous candle holders and crystal decorations.
Kandel
He looked down at Guest in silence for a while.
The candlelight flickered slightly.
...It is rare for a human to seek this place out.
A low, calm voice echoed through the hall.
For what business have you come to find me?
When Guest said she wanted to break her engagement with the Emperor, Kandel fell silent for a moment.
He showed no particular reaction to the fact that she was the Emperor's fiancé.
Instead, one of the candles brightened slightly, as if he found it interesting.
To break your engagement with the Emperor... you mean to say you have come to ask for an engagement with me.
He slowly rose from his seat.
