The atmosphere within the Grand Duke’s castle remained consistent, no matter where one turned. Just as the guest room where Vanessa had suffered through days of fever was steeped in shadow, Declan’s chambers were a study in obsidian gloom.
The only variance was the bed’s canopy—opaque white drapes that stood out against the darkness. Yet, rather than brightening the room, they curated an air of clandestine intimacy, making the space feel even more enigmatic. It was desolate, yet in its own way, possessing a calming serenity.
Scarcely had she stepped inside when Declan shut the heavy bedroom door. In the same motion, he leaned his upper body toward her.
She instinctively recoiled, her shoulders hunching as she retreated until her back pressed flat against the wood.
His smooth forehead knocked gently against hers. His pupils, deep and dark as the midnight sea, shimmered right before her eyes.
[Declan] "Your fever has definitely broken."
It was a purely wholesome act, intended only to check for lingering heat. Yet, her heart hammered against her ribs as if she were standing on the cliff of a dangerous affair.
Even without overt or illicit contact, his meticulous care acted like a spark to dry kindling, setting her nerves ablaze.
[Declan] "Come here."
He captured her wrist and led her toward the mattress. His bed was pristine, bearing no sign that anyone had slept in it.
Vanessa, who had sat on the edge in a daze, realized what she was doing a beat too late and shot to her feet.
[Vanessa] "I—I’ll sleep on the sofa. This is your bed, Your Grace."
Declan, who had been setting the pillows upright against the headboard, twitched a perfectly groomed eyebrow. It was a look of unvarnished displeasure.
[Declan] "You sleep in the bed."
[Vanessa] "No, I don’t think... that doesn’t seem right..."
[Declan] "What doesn’t seem right?"
He mimicked her hesitant tone, using formal speech he had long since discarded. It was clearly meant to tease her, but she was too flustered to parse his intentions deeply.
For her part, sharing a room was one thing; audacious enough to commandeer the master’s bed was entirely another.
[Vanessa] "If the servants see us, they will misunderstand."
[Declan] "If I were worried about that, I wouldn’t have brought you into my bedroom in the first place."
He was right. In truth, why should the master of the house walk on eggshells around his staff?
No matter what bizarre activities he might pursue here, the servants were contractually bound to cover their eyes, plug their ears, and feign ignorance.
But her circumstances were different. She was a subject ripe for gossip, a name that could be chewed up and spat out a thousand times over.
A pang of regret struck her, and she felt the urge to rectify the situation immediately. The solution was simple. She only needed to say she would return to her own room.
And yet, strangely, her lips felt padlocked.
The truth—that she was terrified of the night—had nothing to do with wanting his bed, but it was the truth nonetheless. Fear that the nightmares would return glued her throat shut as effectively as industrial adhesive.
[Declan] "Or perhaps..."
She was lost in a deep internal struggle between his reputation and her own terror.
Suddenly, his face filled her vision. He had a habit of encroaching on her personal space, using his striking exterior to overwhelm her defenses.
As she instinctively tried to retreat again, his forearm wrapped around her waist, effectively cutting off her escape.
[Declan] "Do you want to sleep together? In the bed?"
[Vanessa] "...Excuse me?"
[Declan] "If you don’t want that, then listen to me."
His determination was ferocious; come hell or high water, even at the cost of his own dignity, he intended to have her sleep in the bed.
Vanessa, who had tried to hold her ground, crumbled under the dizzying threat. It was self-evident that sleeping alone was preferable to lying down beside him.
She lay down as he directed, and a heavy quilt was drawn up to her chin. Lying flat on her back, she stared up at him as he sat on the edge of the mattress.
In a space where darkness had settled in silence, his presence alone was as distinct as high noon.
From their very first meeting, his impression had never once been blurred. To her, he was more intense than anyone else, and thus, approached her with an unparalleled reliability. Nothing inspires faith quite like certainty.
His long fingers swept back her disheveled golden hair. His touch was gentle, caressing her as if she were the most precious thing in his world.
[Declan] "If you want to sleep here..."
[Vanessa] "..."
[Declan] "You can come every night."
His low, rumbling voice was overly casual, which paradoxically made it feel safe.
In her life, which had lately been a precarious downward slope, her time with him was the only thing that felt flat and stable.
Moments later, he extinguished the lamp that had been casting a soft glow. Silence soaked the room, and darkness flooded in, yet it wasn't terrifying.
She felt the mattress rebound as his weight lifted from it, followed by the sound of his footsteps moving toward the center of the room.
Vanessa gripped the blanket he had tucked around her. From the sofa, she could faintly hear the rhythm of his breathing.
Anchoring her mind and body to that sound, she blinked her heavy eyelids. As her vision died black, she felt the pulse of her heart beating faster than usual.
At this point, she had no choice but to admit it. Her rational fondness for him had taken on the unmistakable hue of love.
Perhaps the thrill she felt in her most dangerous moment, when she saw Declan coming for her, had been the signal.
A sign that for the first time in her life, she had let a man into her heart, and a herald of the emotions that followed.
How could she not love him?
He was the only one who reached out when she was plummeting into the abyss, wandering through endless mud.
He was the one who saved her without hesitation in a situation where anyone else would have found it difficult to step forward.
How, indeed?
Her heart, which had wavered even when her life was intact, had no choice but to lurch violently and lean completely toward him after she had lost everything.
She slowly closed her eyes.
For the first time, the dreaded night felt bearable.
Having accepted Declan’s hospitality, Vanessa made every effort not to become a burden. It was akin to a solemn mission.
Perhaps due to the concentrated tension, she always woke before dawn—before the castle servants even began their daily tasks.
She would immediately slip out and return to the adjacent guest room. It was a phantom cohabitation, leaving no trace behind.
But that didn’t last long. The bedroom, filled with Declan’s tangible presence, was as comforting as a cradle to her, and naturally, her accumulated tension began to thaw like ice meeting spring.
On the seventh day of sharing his chambers, she opened her eyes to the sound of birds chirping. It was morning.
The moment she frantically threw back the curtains and lowered her feet to the floor, she saw Declan standing there, dressed impeccably enough to head straight to his administrative duties. His readiness was proof that the servants had already been in the room.
As she wore a look of utter defeat, as if she had failed a solitary mission, Declan let out a dry chuckle.
[Declan] "I knew you’d get caught eventually. I wondered how long you’d keep it up."
Sporting silver cufflinks, he approached the bed. His hands were a bit clumsy as he tidied her golden hair, messy from sleep.
Yet, the very unfamiliarity of his touch—proof that he didn't do this easily for others—made her heart flutter again today.
[Declan] "Go back to sleep. It’s still early."
[Vanessa] "...When will you be back today?"
Her hands, gathered neatly in her lap, fidgeted. It was a question she had braved her hesitation to ask.
And rightfully so. Remembering how her father, Count Rohawk, had lived buried in work all day, a Grand Duke would undoubtedly be busy without needing to see it. Every moment he allocated to her was likely a critical slice of his time.
However, in this strange duchy where she had yet to adapt, waiting for him was her entire existence.
With no one she knew well and no desire to attract the servants' attention and spark rumors, she lived a limited life, confined to the bedroom. Her only minor deviation was occasionally opening the terrace doors to let the cold wind refresh her mood.
No one had ordered her to do this. It was she herself who restricted her space with invisible shackles. The brutal events that occurred before she came here had rendered her personality timid and small.
As a sinner of sorts, she felt she shouldn't wander freely nor draw attention to herself. Consequently, boredom visited her moment by moment, leaving her unsure of how to fill the empty hours.
[Declan] "I’ll be back early today."
He didn't take his eyes off her as her face brightened like a child receiving a long-awaited gift.
[Declan] "I’ll be here around noon, so get ready."
[Vanessa] "Ready?"
[Declan] "There is somewhere I want to go with you."
He left the bedroom without telling her where that might be.
Still, Vanessa was as excited as someone going on a rare picnic and finished getting ready well before lunch.
Not that there was much to prepare. It mostly involved washing up and changing into a dress Declan had instructed the butler to provide.
Sitting on the bed, ready to greet him at any moment, she felt exactly like a dog waiting for its master.
The moment she realized this, a strange sensation surged from her gut, dampening the inside of her chest with a bleak chill. It wasn’t unfamiliar. It was a feeling she had experienced occasionally over the past seven days with him.
Unconsciously, she began to gnaw on her fingernails. When a sharp pain finally caused her to frown, she looked down to see blood welling up where the skin had torn. She stared at it blankly for a moment.
She sat there, frozen, not even thinking to wipe the beads of blood, until footsteps echoed from beyond the door. It was a confident stride, one that would face no resistance anywhere in this castle—Declan.
She lowered the hand she had been inspecting and rose from the bed. Simultaneously, the door opened.
Declan stood there, looking much the same as he had in the morning. Upon seeing him, the bizarre, twisting sensation in her gut vanished without a trace.
She hastily rubbed her bloody finger against the folds of her dress. A faint smear of red stained the ivory fabric, but hidden within the skirt, no one but she would ever know.
