How to Survive as the Monster Duke's Wife
Episode 30 What do I say when I meet my father, that person, in the Sunlands?
Illyin was now the Duchess of Biften.
As the mistress of the Biften family, each of her actions was directly connected to the prestige of the Biften family.
Can I really be confident in front of him? Won't I fail to meet his gaze like in my dream?
"Madam?"
"Is there something uncomfortable?"
When Illyin's complexion darkened, Nessie and Mito carefully examined her.
Illyin shook her head.
"If it's alright, could I see the clothes His Highness will wear?"
We prepared such thick clothes here, but Aden's clothes probably wouldn't be in a different state.
The two Maids, who looked at each other, willingly bowed their heads to Illyin.
"We will escort you."
\\
Illyin only realized why the two Maids exchanged glances after following them.
The place the Maids took her to was the 7th floor, in front of Aden's room.
"Illyin?"
Aden looked a little surprised.
Before Illyin could grasp the situation, the door closed and the Maids retreated.
Somehow, she felt like she caught a glimpse of the Maids' mischievous expressions before the door closed.
In an instant, only the two of them were left.
In the end, Illyin could only face him with a slightly surprised look.
"Den went to look around the mansion..."
That was the reason Illyin was wandering around the mansion alone.
Aden smiled.
"Aegis is leading the Knights."
It seemed they had only spread the rumor that 'Den, the Knight Commander of Delos,' was looking around the mansion.
It seemed to be the hardship of playing two roles at once.
Illyin, who understood, smiled slightly.
"Then, are those the clothes you're going to wear out tomorrow?"
"Yes."
Illyin examined Aden's clothes.
Certainly, they were much lighter than the clothes she had just seen.
Since they were the clothes of the Winter Duke, who hardly felt the cold, he clearly didn't pay much attention to warmth.
"Um... I heard that the Winter Duke doesn't feel the cold easily, is that true?"
"That's true, but,"
Aden hesitated for a moment before speaking.
"It might not be the case in the Sunlands."
He spread out his hand.
A faint blue light spread out.
Then, the temperature in the room quickly rose.
The temperature rose to the point where she felt heat beyond warmth, and as soon as he withdrew his hand, it turned cold in an instant.
That meant his Authority was freely available in the Winter Territory.
"I heard that you can't use Authority outside the Winter Territory."
Saying 'I heard' uncertainly meant that he had never been out himself.
Illyin looked at his clothes again.
Still, they looked warm since they were Winter Territory clothes.
But it seemed like it would be a little cold in the evening...
Illyin found a thicker-looking piece of clothing among the clothes around her.
"Just a moment,"
Her delicate hand grabbed Aden's outer garment.
Aden froze without realizing it when her hand suddenly touched near his collarbone.
The sound of the top button being undone echoed particularly loudly in the room.
Illyin's hand slowly moved downwards, opening the buttons.
"..."
Aden, who was looking at Illyin, inhaled briefly.
She was carefully unbuttoning his buttons one by one with her small hands.
Oh dear.
It seemed that Aden was the only one having impure thoughts.
Illyin was just helping him take off his clothes comfortably with a pure face.
That's why it's driving him even more crazy.
Aden closed his eyes and deliberately looked a little further away.
There was a full-length mirror a little distance away.
In his gaze, Illyin's neatly arranged back was visible.
"..."
Perhaps because she was concentrating, that short moment felt very long.
Illyin was slightly opening her mouth and undoing the last button.
"Rather than this outfit―"
When she raised her gaze, the two people's eyes met.
Illyin, who tilted her head slightly, smiled.
She reached out and further opened the clothes he was wearing.
Her hand was felt directly through the thin shirt.
Even the small tremors, as if even the faint heartbeat was heard.
"Illyin,"
He couldn't stand it.
In the end, Aden grabbed Illyin's hand.
Illyin's hand, pressed by him, touched his chest.
The room, which was also used as an office, had unusually strong lighting.
As if the inside would be visible through the white shirt.
Illyin looked at her hand touching the white shirt, and then, startled, let go of her hand.
No, she was about to let go.
Aden grabbed her wrist.
As her body turned, Illyin unknowingly faced the mirror.
Aden had his eyes closed.
Her two hands were held up as if saying, 'Freeze!'
"...Den?"
Aden's body temperature was directly transmitted from their clasped hands.
Illyin's small voice echoed in the quiet room.
Aden let out a deep breath.
"Do you know that... your scent is stimulating?"
Illyin blinked.
Before she could understand the meaning of the words, Aden lowered his head towards her.
His kisses poured down from the top of her head.
As if a very intense thing was flowing down from the top of her head, his lips, which slowly came down, gently bit Illyin's ear.
"...Do you want to see me struggling?"
With such a pure face.
Aden slightly opened his eyes and looked at her.
He took a deep breath of hot air.
Under the long, dark eyelashes that received the bright light, his deep blue eyes shone dangerously.
"Of course not,"
Illyin, who answered without realizing it, let out a small scream without realizing it when he boldly groped around her chest.
Aden smiled.
"Then you want to test me."
Before Illyin could ask anything back.
Aden deeply buried himself in her.
He, who let out a ticklish breath, whispered.
"I don't think I can handle it."
Punish me for being like this.
Aden kissed Illyin in a completely different way from his innocent words.
It was such an intense kiss that Illyin's body lost strength.
\\
The preparations for the trip to the Sunlands were quickly completed.
The people of Delos diligently finished the preparations, worrying about everything from how cold the winter in the Sunlands would be to whether the food in the Sunlands would suit His Highness the Duke, with all sorts of trivial and big concerns.
"It will be cold outside the mansion."
Before departure, Aden repeatedly adjusted Illyin's clothes.
Illyin looked out the window.
Snowstorms were raging to the point where she wondered if there weren't originally white stains on the transparent window.
"April..."
Illyin murmured softly.
Aden, who couldn't have failed to hear, nodded.
"Yes, it's April."
Come to think of it, Aegis also said that even people from the Winter Territory don't usually go outside during this period.
Illyin, newly worried, looked out the window again.
"The preparations for departure are complete."
At that time, Aegis, who entered the mansion, politely greeted the two.
"Are you very worried?"
Aden asked Illyin softly.
Illyin glanced out the window.
She was about to shake her head without realizing it, saying no, but Aden cupped her cheeks with both hands.
His warm hands melted her, who was unknowingly freezing.
"...Are you worried?"
The reason he's asking that again now is probably because he knows I'm avoiding my father.
Illyin smiled at him with gratitude.
"I'm worried."
"What are you worried about?"
Aden's voice always has unwavering certainty.
Illyin looked up at his face.
Did they say that they couldn't leave the Winter Territory if they saw his face?
His words sounded like he wouldn't let go of her no matter what he did.
That was a word that repeatedly gave Illyin stability.
Even if I waver, Aden doesn't waver.
Illyin was going to become stronger and stronger.
So, she has no worries now.
"It looks too cold."
It was a joke.
Illyin smiled.
But Aden seemed to have taken it seriously for some reason.
His gaze turned to the window.
To him, a winter person, it was a common April snowstorm.
Today wasn't a particularly severe level.
But it might not be the case for Illyin, a Sunfolk.
He reached out and lifted the shawl that covered Illyin's Exposed neckline.
Before Illyin's Exposed neckline could get chilly, Aden spread out his other hand.
The blue light representing Authority sparkled.
Then, the temperature around the mansion noticeably increased.
Not only that, but the wind that was roughly blowing the snow also lost its strength and became blurred.
"How is it now?"
"Now, it's alright."
It was really alright.
Illyin grabbed his hand tightly.
His warm hand was reassuring.
\\
The Delos carriage heading to the Sunlands was running at a fast pace.
The snowstorm that hindered the carriage's progress was powerless in the face of the Lord's Authority.
Even if they couldn't make the entire Winter Territory like the Sunlands, the current master of the Winter Territory was the one with the most powerful Authority among the past Dukes.
It was enough to lower the temperature in April to the point where the Yester race was wary, and to comfortably clear the path for one carriage.
"Your Highness, are you alright?"
The adjutant Aegis was worried that he was using too much Authority.
There is no power without a price.
Even if he didn't know in detail how Authority was achieved, there were records that the more Authority a Duke used, the faster his body weakened.
"I'm alright."
Aegis examined Aden's complexion.
Only after seeing his usual appearance did he step back.
There were only four people in the carriage, including Etra.
Aegis once again erased his presence, silencing his voice as if he were no one, like Etra.
The only one who occasionally flinched in the quiet carriage was Illyin.
Her eyes, covered by the Blue Nose cloth, were closed.
Aden, seeing that she had fallen asleep deeper than he thought, checked the temperature of her hands and feet again.
Fortunately, thanks to Authority, it seemed that the inside of the carriage wasn't cold for her either.
Aden, who had placed his hand on Illyin's forehead just in case, grabbed her hand again.
At that time, Illyin grabbed his hand tightly.
"Illyin?"
Aden, surprised, turned to look at Illyin's face.
\\
Thanks to the ever-present white snowdrifts and raging snowstorms, and the sky that never cleared of dark clouds, the color of Biften was generally dim.
It was a distinctly different place from the Sunlands, where various colors were combined each season to provide different colorfulness throughout the four seasons.
So, Illyin knew as soon as she opened her eyes.
「...?」
This was definitely the Sunlands.
She could tell just by looking at the road where the soil was exposed without being buried in snow, and the tree trunks.
And she in the dream was on a horse.
「Illyin, hold on tight.」
What she heard was Aden's voice.
Illyin in the dream checked her feet on the stirrups again, worried about falling from the swaying horse.
And there was a Mobile swaying there, out of place.
It was a Precognitive dream.
Illyin, who was watching, suddenly felt a chill on her Exposed neckline.
She quickly scanned her surroundings.
The group was being chased.
In a place that was barely visible and far away, she could see the appearance of a shattered carriage.
It was the carriage she had been riding in until she had the dream.
Those who were following the group were all wearing black masks.
Illyin saw Aegis, who was following behind, knocking down several arrows with his sword.
「Your Highness, it will be difficult to shake off the pursuit like this.」
「Can you hold out until we reach Winter?」
Winter... He was talking about Biften.
Illyin, who was watching the dream, quickly examined the front of the group.
There was no place that looked like Biften yet.
The situation was too bad.
