The night did not come when she expected it to.
That was how Seo Yerin understood the difference.
The household prepared, then paused. Lanterns were lit, then left untrimmed. Incense was selected, then set aside untouched. Servants moved with the careful economy of people waiting for confirmation that never arrived.
Yerin noticed all of it.
She had already bathed. She had already dressed. The robe she wore was darker than the one from the night before, its silk softer, looser, tied at the waist with a knot she could undo in a single motion. Her hair was unbound, falling straight down her back, still faintly cool from drying.
She stood in her chamber and waited.
At first, the waiting felt familiar—an extension of what she had already learned. Stillness. Readiness. Composure. But as the hour stretched, something in her awareness failed to settle.
It did not sharpen.
It lingered.
She shifted her weight once, then corrected herself. The silk brushed against her thighs, the sensation clearer than it should have been. She drew a slow breath and held it, then released it carefully.
Nothing happened.
The household bell rang.
Still nothing.
That was when she recognized it—not as thought, not as emotion, but as absence with shape.
She was ready.
And there was no one to receive it.

Muyeon entered late.
He did not look surprised to find her waiting. His gaze passed over her briefly, noting the robe, the posture, the way she had arranged herself without instruction.
"You prepared," he said.
"Yes."
He poured tea and drank it slowly. "There will be no guest tonight."
She absorbed the words without reacting outwardly.
"I see," she said.
Muyeon studied her for a moment longer than usual. "Do you?"
"Yes."
He set the cup down. "Tell me what you feel."
The question was deliberate.
She considered it carefully. "I feel… unfinished."
The word surprised her as soon as it left her mouth.
Muyeon did not comment immediately. He rose and approached her, stopping close enough that she felt his presence distinctly.
"That," he said at last, "is the beginning of craving."
She did not look away.
"It is not desire," he continued calmly. "Not yet. Desire seeks. Craving waits."
She listened.
"You prepared without instruction," he said. "You remained ready without reward. Now the absence has registered."
He stepped back. "That is dangerous."
She inclined her head. "And useful."
"Yes," Muyeon agreed. "If managed."
He dismissed her shortly after.
***
Sleep did not come easily.
Not because her mind raced, but because her body refused to fully relax. Awareness remained just beneath the surface, not demanding, not sharp—simply present, as though it had not yet been given permission to fade.
She lay still until it passed.
Eventually, it did.
But it took longer than it should have.
***
The next evening, the household prepared again.
This time, the preparations were unmistakable. Lanterns were lit decisively. Incense burned early. Screens were drawn fully, and servants withdrew without needing to be told.
Yerin did not wait for summons.
She dressed immediately.
The robe she chose was pale and thin, the silk soft enough that it clung faintly to warmth. It tied at the shoulders and once at the waist. She wore nothing beneath it. Her hair was left unbound again, framing her face and falling down her back in a smooth line.
She stood ready when the door opened.
The guest who entered was unfamiliar—quiet, composed, carrying himself with the confidence of someone accustomed to being accommodated without ceremony. His gaze lingered on her openly, not hurried, not apologetic.
Muyeon greeted him with practiced ease.
Yerin stood where she was placed, posture composed, chin level. The robe shifted slightly as she breathed, the fabric parting and settling with each movement.
Conversation began.
It was slow, deliberate, unhurried. The guest spoke of recent travels, of negotiations conducted quietly rather than announced. Muyeon listened attentively, responding with measured interest.
Yerin poured wine when asked.
As she leaned forward, the robe parted at her chest, revealing bare skin beneath the lanternlight. She did not correct it immediately.
The guest's gaze followed the movement.
Muyeon noticed.
"You may speak freely," Muyeon said to him. "You are among friends."
The guest smiled faintly. "Then I will be direct."
He turned his attention fully to Yerin. "You were described as attentive."
She met his gaze calmly. "I am."
"Attentive to instruction," he clarified.
"Yes."
"And what happens," he asked, "when instruction is delayed?"
She answered honestly. "I remain ready."
Muyeon watched her closely as she spoke.
The guest stood and approached her slowly. He did not touch her at first. He stopped close enough that she felt the warmth of him, the subtle shift in air between their bodies.
"You are prepared already," he observed.
"Yes."
He looked at Muyeon. "You train her thoroughly."
Muyeon inclined his head. "She learns quickly."
The guest returned his attention to her. "Remove it."
She reached for the knot at her waist and loosened it without haste. The robe parted smoothly, sliding open to reveal bare skin beneath—first her stomach, then the line of her ribs, then the full curve of her chest as the fabric slipped from her shoulders.
She let it fall to the floor.
She stepped out of it.
She stood naked beneath the lanternlight, posture composed, breathing even, awareness gathered but controlled.
The guest exhaled slowly.
He reached out and placed his hands at her waist, fingers spreading as if to confirm balance rather than possession. He drew closer, testing proximity before committing to it.
She did not resist.
She did not lean in.
She remained where she was.
When he kissed her, it was unhurried.
His mouth pressed to hers and lingered, the contact stretching, deepening gradually. His hands steadied her at the waist, then moved slowly along her back, guiding her closer until there was no longer space between them.
Her breathing deepened.
The kiss broke and returned, his mouth tracing along her jaw, lingering at her throat. One hand slid higher, fingers brushing skin with deliberate familiarity.
"You are very still," he murmured.
"I am listening," she replied.
He smiled faintly at that.
His hands began to guide her backward toward the inner chamber, bodies aligned, intention unmistakable. The curtain stirred as his hand reached for it.
The moment held—long, heavy, complete.
And then it broke.
***
Later, alone in the bath, Yerin stood beneath cooling water and recognized the difference.
The awareness did not fade as quickly as it once had.
It did not trouble her.
But it remained longer than necessary.
She did not name it.
She did not resist it.
She simply acknowledged its presence and let it settle where it wished.
When she returned to the marital chamber, Muyeon was waiting.
"You were disappointed," he said calmly.
She did not deny it. "Yes."
"That is the first honest answer you have given me about this," he observed.
She met his gaze. "I did not seek it. It arrived."
Muyeon nodded. "Craving always does."
He regarded her thoughtfully. "You will learn to carry it without acting on it."
She inclined her head. "Until instructed."
"Yes," he said. "Until instructed."
She lay down to sleep shortly after.
This time, when she closed her eyes, the absence returned briefly—
Then eased.
But it did not disappear.
