The Solenne line had not always been forgotten.

Once they ruled the thin places—those fragile seams where the waking world brushed against the dream-realm. They were Dreamwalkers in the truest sense: blood that could step fully into another’s sleep, mend fractured minds, bind restless spirits, and, in the oldest records, even pull the dying back from the final dark by walking with them through their last fever. Their power was radiant and terrible. A fully awakened Solenne could rewrite the edges of reality while the world slept.

The cost of that power was written in blood long before the seals.

In the final century of their reign, the last great heir—Seraphine Solenne—lost control during a winter plague.

The fever that should have opened her gifts instead tore the veil wide.

Entire villages dreamed themselves to death. People walked into the snow believing they were home. Children never woke. Reality itself began to fray in places that still carry the scars as “thin spots” where time slips and shadows move wrong. The surviving guardians and the remaining Solenne blood forced a binding so absolute it nearly erased the line from history.

They sealed the magic into the blood itself, locking it behind generational wards that would only crack under extreme fever—and only in the presence of a living guardian bound by the oldest oath.

That oath was never meant to be gentle.

A blood-oath guardian did not simply protect. He absorbed.

Every excess surge of Solenne power that threatened to burn the heir alive was drawn into the guardian’s own body and soul. Over years the accumulated magic changed him: slowed his aging, sharpened his senses in the dream-realm, and slowly hollowed out everything that was not the oath.

Love for others faded. Ambition withered. The longer a guardian served, the more he became a living anchor and nothing else—until the heir either mastered the power or died.

Most guardians eventually burned out from the inside, their own hearts turning to quiet ash while they continued to function. The final price, whispered only among the oldest records, was that when the last seal broke, the guardian’s life became permanently tethered to the heir’s.

If she fell, he fell with her.

There was no severance.

No retirement.

No ordinary death.

Jungkook had known the cost the night the oath took him.

He had been seventeen, kneeling in the candlelit room where Lisa’s mother lay dying, the infant already crying with a fever that should not have existed in a newborn.

The old words had been spoken over his blood and hers. Something irreversible had locked into place behind his ribs.

From that moment he could feel her—distant at first, then sharper with every year.

Her dreams called him. Her pain reached him.

And every time he stepped into the fever-dreams to take the overflow of her awakening power, a little more of himself was given in exchange. He had already lost the ability to want anyone else. The cold distance he maintained in the waking world was not only strategy; it was the oath protecting what little of him remained. Touching her while she was conscious would accelerate the final unraveling. Once the last ward broke, there would be no more careful containment. Only the two of them, bound until the end of whatever lives they had left.

He had told himself for years that the cost was acceptable.

He was no longer certain.

***

That night the dream opened differently.

The usual soft bedroom was gone. Instead he found himself standing in a vast, ruined hall of black stone and shattered stained glass—the ancestral seat of the Solenne line as it existed in the oldest memories the magic still carried.

Rain fell through the broken roof.

Lisa stood in the center of the cracked floor, barefoot, wearing only the thin white slip she sometimes dreamed in. She was already looking at him when he appeared, and the expression on her face was not the usual dazed hunger.

It was recognition, half-formed and frightened.

Jungkook crossed the distance slowly.

When he reached her he did not pull her into a kiss at once. He simply rested his forehead against hers, breathing her in, feeling the restless surge of power already rising under her skin.

“You’re remembering pieces,” he said quietly. “Even though you shouldn’t.”

Lisa’s hands came up to rest against his chest, not quite pushing him away.

“I woke up hurting,” she whispered. “Here.” She pressed her palm over her own heart. “And I kept thinking about you. Not the way I usually do. Not the… the heat. Just you. Standing in the kitchen last week, not looking at me. And it felt like something was breaking.”

He closed his eyes. The oath stirred, heavy and cold, warning him that every word spoken in this place risked bleeding into her waking mind.

He spoke anyway.

“The blood-oath that binds me to you is older than the seals. It was made so that no Solenne heir would ever face the awakening alone. Every time I come to you like this, every time I take the excess magic so it doesn’t burn you out, I pay with pieces of myself. My own life. My ability to want anything that isn’t you. One day there will be nothing left of me except the duty.” His hands slid up her arms, gentle, almost reverent. “That is the cost. And I accepted it the night you were born.”

Lisa’s breath hitched. Tears gathered at the corners of her eyes, catching the dream-rain.

“Why?”

“Because the alternative was watching you die the way your mother almost did. The way every unguarded Solenne eventually does.” He lifted her face with both hands. “I was never supposed to let you see this part. You were never supposed to ask. But you did. And I couldn’t lie to you again.”

She searched his face as if trying to memorize it against the morning that would steal the memory.

Then she rose onto her toes and kissed him.

It was soft. Almost shy. Nothing like the fevered claiming that usually opened their nights. Jungkook made a low sound in his throat and gathered her against him, answering the kiss with the same devastating care he had shown her the night before. He undressed her slowly beneath the broken arches of the ruined hall, laying her down on a bed of soft moss and old velvet that the dream provided. When he entered her it was with a single, trembling thrust that made them both still.

He made love to her like a man already grieving.

Every stroke was deep and unhurried. Every kiss lingered. He held her gaze the entire time, refusing to let either of them hide. When she came it was with a quiet, broken sob, her arms locked around his shoulders as if she could keep him from disappearing with the dawn. He followed her over the edge with a shudder that felt too much like surrender, pouring himself into her while the dream-rain fell around them.

Afterward he did not vanish at once.

He stayed curled around her, one hand splayed over her heart, feeling the dual rhythm of her pulse and the restless magic beneath it. The oath pulsed in answer—already taking its price, already carving another quiet piece out of him.

“I won’t remember,” Lisa murmured against his throat, already drifting.

“I know.”

“But you’ll still be there. In the kitchen. Looking through me.”

“Yes.”

Her fingers tightened in his shirt.

“I hate that.”

Jungkook pressed a final kiss to her hair, eyes open against the slowly dissolving dark of the dream.

“So do I, love,” he whispered. “So do I.”
