Chapter Text
The rain over Seoul hung in the air as a heavy, gray mist that blurred the palace district's ancient stone walls. Inside the secluded annex of Anhwa Hall, the silence was absolute. There were no gilded screens or court officials whispering in the corridors. Just polished walnut timber and a cup of green tea that had long gone cold.
Grand Prince I-an arrived three minutes early, stepping through the side entrance without standard royal fanfare. Only Choi Hyeon, his personal aide, followed a step behind.
"The guest arrived early, Your Highness," Hyeon murmured, keeping his voice low. "She bypassed the primary security checkpoint using a private pass from the Ministry of Administration. No log was entered into the daily registry."
I-an halted before the sliding wooden screen. He stood with his hands in his pockets, his tall frame still. "A private clearance? The Ministry doesn't grant those lightly to civilians. Not even to conglomerate heads."
"She's not an ordinary civilian, Your Highness," Hyeon replied, gently sliding the door open.
The room inside was narrow, lit by a single lamp casting a sharp circle of amber light onto a low table.
Sitting on the far side of that light was the infamous CEO of Castle Beauty.
She didn't rise, nor did she offer a deeply formal greeting. She sat with her spine straight, hands folded over a slim leather portfolio. Dressed in a tailored charcoal wool suit, her dark hair pulled back into a severe bun, she looked exactly like what she was: the picture of a razor-sharp. She had arrived to execute a pre-calculated transaction.
I-an stepped across the threshold, and Hyeon drew the screen shut behind him with a definitive click.
"You took a significant risk coming here through the back channels, Director Seong," I-an said, standing over her. "If the Queen Dowager’s security detail reports this meeting, the morning newspapers won't care about the lack of ceremony. They'll just call it treason."
Hui-ju raised her head, locking her gaze onto his. "The Queen Dowager’s detail is currently occupied with the French trade delegation at the main palace," she said, her voice smooth and entirely casual. "And the Royal Secretariat won't look into rooms they've been told are empty. Please, Your Highness. Sit. The tea is cold, but our time is limited."
I-an lowered himself onto the cushion opposite her, keeping his overcoat buttoned. He watched her across the short distance.
In Seoul's high society, Seong Hui-ju was a paradox. She had turned a struggling cosmetics subsidiary of Castle Group into an international empire within three years. Yet, behind the accolades lay an asterisk. She was an illegitimate child of Chairman Seong. To her legitimate half-brother, Seong Tae-ju, she was just an interloper.
"I read your recent profile in the Economic Review," I-an said. "Your father’s board just granted you three million stock options. By all accounts, you're the most powerful woman under thirty-five in this country. Why sit in a dark annex, risking a scandal with a sidelined prince?"
Hui-ju looked down at the portfolio. "Stock options are paper, Your Highness. They can be granted on Tuesday and stripped away by a family council on Wednesday if the patriarch’s health fails."
She lifted her eyes. "My brother, Tae-ju, spent the weekend dining with the Minister of Economy. His wife’s family just acquired another ten percent of voting shares. When my father passes, the corporate charter will revert to the legitimate bloodline. The board always aligns with tradition."
"You have wealth," I-an observed.
"Wealth is temporary when you don't own the ground it's built on," Hui-ju replied flatly. "Money can't buy you the right to keep your seat when the true heirs clear the room. The stigma of my birth isn't something I can out-earn. If I double our revenue, I'm still just the bastard daughter who performed well.
“I'm looking for a legitimacy so absolute that not even Castle Group’s legal team can find a flaw in it. I want to belong to the only institution that sits above them."
I-an let her words settle. He knew the weight of her ambition, but he also knew the reality of his own position. As Regent, he held the executive authority of the monarchy during King I-yun's minority, yet that power was a gilded cage. He was structurally constrained by the Prime Minister's office and heavily monitored by the Queen Dowager’s faction, who treated his regency as a temporary inconvenience.
"You speak of legitimacy," I-an said. "But you're addressing a Regent who is legally forbidden from owning private assets, whose state decrees are fought over by cabinet ministers, and whose residence is staffed by intelligence spies."
"I'm aware," Hui-ju said. "I know the Prime Minister cut your northern development budget by forty percent last month, trying to squeeze your executive authority. You're the Regent, Your Highness, but you're also a prisoner within your own courtyard."
"A comfortable prison," I-an remarked dryly.
"An unstable one," Hui-ju corrected. "The young King turns twelve next winter. The Queen Dowager is already drafting paperwork to extend her influence, aiming to terminate your regency early. When the young King reaches his majority, your temporary power evaporates. You'll be an uncle with a high title and a small pension, waiting for the government to decide which villa you're allowed to die in."
I-an felt a small spark of amusement. Politicians always used flowery language while trying to undermine his regency. Hui-ju treated him like an underutilized asset on a balance sheet.
"You've done your research," I-an noted.
"I don't enter negotiations without checking the credit rating," she replied casually. "You need resources that don't come from the state budget to solidify your position. And you need a reason for the public to demand your presence when your regency ends. We're both living on borrowed time, Grand Prince. The only difference is that I have the capital to buy the clock."
Hui-ju slid the black leather portfolio across the polished table. "The initial terms are inside. It's drafted like a standard corporate restructuring agreement, but altered to fit the civil code governing royal marriages."
I-an looked down at it. "A contract marriage."
"A structural partnership," Hui-ju clarified. "Let's avoid the sentimental language of television dramas. I'm not offering romance, and I'm not asking for your affection. I'm proposing a pact."
"Walk me through the ledger," I-an said, leaning forward into the amber light.
"Upon our engagement, Castle Group—through my private holding firm—will establish a cultural foundation dedicated to royal heritage," Hui-ju explained smoothly.
"The initial endowment will be two hundred billion won. You'll be named permanent executive chairman with full, un-auditable control. The state can't touch it because the capital will be private, giving you financial leverage the Prime Minister can't veto."
I-an’s eyes narrowed. "Two hundred billion won is an expensive wedding gift."
"It's an investment. In exchange, the Royal Household will register my name as your primary consort. When the public looks at me, they'll see the Grand Princess and wife of the Regent, not an illegitimate daughter. My half-brother will be completely neutralized."
"And the public narrative?" I-an asked. "The citizens expect their royals to look capable of human feeling."
"My public relations division will handle it. We met through a mutual interest in traditional arts, had three private dinners over six months, and discovered an alignment of values. It'll be clean, dignified, and entirely dull. The public loves a dignified romance because it gives them nothing to gossip about."
I-an studied her. There wasn't a trace of warmth in her eyes, just clear, transparent ambition. "A marriage within the royal house requires the Queen Dowager's consent," he noted. "As Regent, I can sign off on state matters, but she still holds the final veto on family alliances. She'll never sign off on something that gives me independent capital."
"The Queen Dowager’s primary corporate benefactor is the Min family," Hui-ju replied without blinking.
"Min Jeong-woo is trying to secure a logistics contract for Castle Group’s domestic ports. If I block that contract, the Min family loses forty billion won by the third quarter. The Queen Dowager will sign because her backers can't afford to let me ruin their supply chain."
I-an let out a quiet breath that was almost a laugh. "You really don't leave any room for negotiation, do you?"
"Negotiation is for people who are unsure of their value," Hui-ju said.
The air in the room suddenly tightened. Hui-ju shifted her posture, her voice carrying a distinct, heavy weight.
"There's a second section to the contract," she said, her eyes locked onto his. "On page twelve. It's a clause that won't be included in the drafts sent to the ministries or the legal teams. Only you and I will ever know it exists."
I-an kept his hand flat against the folder. "Go on."
"The marriage must produce an heir," Hui-ju said. She didn't blink or blush. "Within twenty-four months of the ceremony, we must present an heir registered under both the House of I and the primary inheritance line of Castle Group."
I-an’s hand went entirely still. "An heir," he repeated, the word heavy in the quiet room.
"An heir," Hui-ju confirmed. "Under royal succession law, any child born to you within a legal marriage is automatically granted titles from birth. And as current Regent, your firstborn holds immediate political gravity. Under the new trust structure I'm establishing, my personal shares will automatically bypass my brother and transfer directly to my child.
“Within two years, we'll create a person who can't be touched by palace politicians or corporate executives. They'll be the future of both institutions, and no one will be allowed to question their right to exist."
I-an looked at her. This wasn't just a transaction. It was an architecture of survival. "An heir requires more than a signature, Director Seong. You're talking about a child born into a war zone between our families."
"A child born into a war zone with a steel fortress around them is safer than a child born outside the walls with no armor at all," Hui-ju replied without an ounce of softness. "I'm not asking you for a family, Regent. I'm asking for a permanent lock on the future."
I-an pulled his hand away and leaned back. "Let's be entirely honest. You're an exceptionally intelligent woman, Hui-ju. If this were simply about neutralizing your brother, the title and the foundation would be enough. Why the child? This feels less like strategy and more like a trap."
"It's simple logic," she answered simply.
"Is it? A child ensures that even after my regency concludes, you remain permanently tethered to the royal house through blood. The Queen Dowager would be forced to protect you because your child would be part of the direct line of succession."
"That's not a trap, Your Highness," Hui-ju said casually. "In business, we don't invest all our capital into a single sector. A regency can be limited by a political vote, but blood can't be legislated out of existence."
"And the consequences?" I-an pressed. "The Min family and your brother won't just file lawsuits. They'll try to destroy you before the child is even born. They'll turn your life into a public spectacle."
"They're already doing that," Hui-ju said, her voice dropping into a flat, cold indifference. "My brother hired private spies to follow my secretary last year. The Min family controls tabloids that run stories about my mother’s background every time I launch a new product line. I'm already standing in the middle of the firing range, Your Highness. I'm simply choosing to stand behind a larger shield."
"You're assuming I'm willing to stand there with you," I-an noted.
"I'm assuming you prefer a fight where you have a chance of winning over a slow death in an empty courtyard," she replied.
I-an searched her face for any tremor, but her control was absolute. "You've achieved more by twenty-eight than most men in your family have in their lifetimes," he said quietly. "Why does the approval of a traditional board matter so much? Why do you care what they think of your birth?"
Hui-ju looked toward the dark wood of the sliding screen, her expression settling into something deep and heavy.
"Because success in this country is an illusion if you don't have the lineage to anchor it," she said. "When I was twelve, my father brought me to the main house for New Year’s. My brother Tae-ju was given a traditional gold seal that belonged to our great-grandfather. I was given a seat at the children's table in the back room and told to be grateful I was allowed through the gate."
She looked back at I-an, her eyes completely clear of tears.
"I spent fifteen years working eighteen hours a day. I saved their failing subsidiary and handed them a global market. And do you know what my father said to me at the last general meeting? He patted my shoulder and told me I was a very dependable worker. Not a daughter. A worker. To them, my achievements are just an apology for my existence. They think they can use my brain to fill their bank accounts and toss me aside when the legitimate son is ready."
She pressed her finger firmly onto the portfolio. "I'm not going to spend the rest of my life waiting for permission to exist. If society won't give me the legitimacy I earned, then I'll take the one thing they can't buy. I'll take the royal name, and build a reality where my brother has to bow to my child before he can even enter the boardroom."
I-an sat entirely still, absorbing the controlled fury beneath her words. He recognized that pressure. He had spent his adult life being a "dependable royal"—and now, even as Regent, he was forced to play the part of a compliant placeholder while the politicians carved up the nation's governance.
Hui-ju wasn't spinning a fairytale. She knew exactly how dirty the palace floors were, and she was choosing to walk in anyway because she had calculated that the knives inside the palace were more efficient than the ones inside her own home.
"You're entirely ruthless, aren't you?" I-an said, a quiet respect entering his deep voice.
"I'm practical," Hui-ju corrected. "Ruthlessness implies an intent to cause harm. I don't care enough about my brother to want to harm him. I simply want to render him irrelevant."
I-an leaned back. Hui-ju was the first person to walk into his presence and display her ambition exactly as it was, without covering it in courtly manners. She wasn't asking him to love or protect her. She was offering an equal partnership in an army of two.
"If we do this," I-an said slowly, "what exactly am I agreeing to on a daily basis? I'm a man of specific habits, Director Seong. I don't tolerate corporate managers interfering with my staff, and I have no desire to perform for entertainment cameras."
Hui-ju’s shoulders dropped a fraction of an inch, the only sign she knew she had passed the most dangerous part of the conversation.
"Your habits will remain entirely your own," she said smoothly. "The public performance will be strictly limited to four state events a year and two charity galas. Beyond that, your life will remain completely autonomous. I have no interest in your daily routine, Your Highness. I have an empire to run."
I-an pulled the portfolio toward himself, flipping the cover open. The pages inside were laid out in a clean legal format. "Let's review the operational details. How do you intend to handle internal security inside my residence? My current staff answers to the Ministry of Interior."
"The moment the engagement is finalized, the cultural foundation will take over the maintenance contract," Hui-ju explained. "We'll replace the current security with a private firm managed by Castle Group’s internal division. The Ministry of Interior will be blocked from accessing the logs under the guise of protecting commercial trade secrets."
"And the duration?" I-an asked, flipping to page five. "A contract of this nature can't be permanent."
"The initial term is five years," Hui-ju said. "That gives us time to establish the foundation, secure my position on the board, and ensure the heir's legal status. After five years, if either party wishes to dissolve the civil marriage, we transition to a permanent legal separation. The public narrative will be an amicable agreement due to the pressures of public service.
"You'll retain foundation control, I'll retain my corporate position, and the child remains the joint heir under a permanent trust."
I-an nodded slowly. "And if your brother attempts a corporate audit, am I expected to use my executive power as Regent to interfere?"
"Absolutely not. I handle my own battles," Hui-ju said. "Your only responsibility is to remain standing next to me during public events, looking exactly like what you are. Let the public see that the throne stands with Castle Beauty. The market will do the rest."
I-an closed the folder with a quiet thud. He hadn't signed anything, but by correcting the logistics, they were already two engineers looking at the blueprint of a machine they were both going to build.
"You're asking for a lot of stability from a man whose current power has an expiration date," I-an noted.
"You have exactly what I need," Hui-ju replied, her gaze meeting his. "You have a name that has survived for six hundred years. My family has only had money for fifty. Let’s see what happens when we combine the two."
The small clock on the wall chimed once, signaling the end of her private clearance hour.
Hui-ju rose from her cushion in a single, fluid motion, looking down at I-an with her familiar cold, corporate efficiency.
"The draft is yours to keep, Your Highness. I'm leaving for Tokyo on the early flight tomorrow morning for a three-day retail conference. I expect your aide to contact my chief secretary by Friday afternoon if you require any modifications to the language on page twelve."
I-an remained seated. "Safe travels, Director Seong."
"Thank you," she said.
She turned and slid the screen open herself, stepping out into the dark corridor where Choi Hyeon stood waiting. She didn't look back, vanishing into the gray mist of the outer courtyard.
Moments later, Hyeon stepped into the room, looking at his master. "Your Highness? Are you alright?"
I-an didn't answer immediately. He reached out, his fingers tracing the cold leather cover of the folder. The stagnant silence that had filled the villa for years felt different now. It felt like the air before a major summer storm.
"Hyeon," I-an said quietly.
"Yes, Your Highness?"
"Cancel my Thursday meetings with the Ministry of Administration," the Grand Prince said, his eyes fixed on the document. "And tell the head manager to ensure my private study is completely swept for listening devices by tomorrow evening."
Hyeon's eyes widened. "Your Highness... are we moving forward with this?"
I-an rose, picking up the portfolio and tucking it securely under his arm. He walked toward the open screen, looking out into the rain-soaked courtyard.
"A contract has already been born in this room, Hyeon," I-an said, his voice entirely calm, but carrying a sudden, dark undercurrent of anticipation. "Now we just have to see who survives the end of it."
