The kingdom of Haneul had one unbreakable law.

"A prince must marry a princess to protect the royal bloodline."

Yet that law was about to become meaningless.

---

The palace echoed with hurried footsteps.

Servants rushed through the endless marble corridors carrying expensive silks, flowers, and golden trays overflowing with jewels.

Outside, musicians rehearsed.

Inside...

Chaos.

"Find Princess Sooyeon!"

The king's voice thundered across the throne room.

Guards immediately bowed.

"Yes, Your Majesty!"

Within minutes, horses galloped through the palace gates.

Every noble house.

Every temple.

Every road leading out of the capital.

Nothing.

The princess had disappeared.

---

Meanwhile...

Hundreds of kilometers away...

Princess Sooyeon removed the heavy crown from her head and threw it into a river.

"I won't live my life as someone's political pawn."

Without looking back...

She vanished into the forest.

---

Back at the palace...

The wedding was only four hours away.

Delegations from neighboring kingdoms had already arrived.

Breaking the alliance would mean war.

The king gripped the armrest of his throne so tightly his knuckles turned white.

"There has to be another way."

Silence.

Then...

An elderly minister slowly stepped forward.

"There is... one possibility."

Everyone looked toward him.

He hesitated.

"It will disgrace the royal family."

The king narrowed his eyes.

"Speak."

The minister took a deep breath.

"The princess has... a younger brother."

The room froze.

Everyone knew who he meant.

---

Prince Kim Taehyung.

Twenty-four years old.

The forgotten prince.

Unlike the rest of the royal family...

Taehyung never attended banquets.

Never participated in politics.

Never smiled for the public.

He spent his days studying history, painting, and wandering the palace gardens alone.

Many nobles whispered that he wasn't fit to be royalty.

Others simply called him...

"The Invisible Prince."

---

One minister objected immediately.

"But he's a man!"

Another added,

"The groom is Crown Prince Jeon Jungkook! The future emperor of the Jeon Empire!"

The elderly minister nodded.

"I know."

"But if this marriage doesn't happen..."

"...thousands will die."

Silence returned.

The king closed his eyes.

Every option led to disaster.

Except one.

---

The palace doors opened.

A servant hurried toward the eastern garden.

---

Far from the panic...

Taehyung sat beneath an enormous cherry blossom tree.

A half-finished painting rested against the grass.

Pink petals drifted through the breeze, landing softly in his dark hair.

He didn't notice.

He was completely absorbed in mixing shades of blue.

Footsteps approached.

Fast.

Urgent.

"Your Highness!"

Taehyung looked up.

Three royal guards stopped before him, breathing heavily.

"The king requests your presence immediately."

Taehyung tilted his head.

"My father?"

"He said... it's an emergency."

Taehyung quietly cleaned the paint from his fingers with a cloth.

Then stood.

"I'll come."

---

The throne room fell silent as he entered.

Unlike everyone else dressed in elaborate robes...

Taehyung wore simple white clothing stained with flecks of blue paint.

His expression remained calm.

"You called for me, Father?"

The king couldn't meet his son's eyes.

Not at first.

Finally...

"There is something only you can do."

Taehyung listened patiently.

"The princess has disappeared."

His eyes widened slightly.

"My sister?"

"Yes."

The king swallowed.

"And..."

"...you must take her place."

For the first time...

Taehyung's composure cracked.

"What?"

"You will marry Crown Prince Jeon Jungkook."

The words hung in the air like a blade.

Taehyung stared at his father, searching for any sign that this was a cruel joke.

There wasn't one.

"You expect me..." His voice was quiet, almost hollow. "To marry a man I've never met... because my sister ran away?"

The king's shoulders sagged.

"I expect you to save this kingdom."

Taehyung looked around the room.

Every minister avoided his gaze.

Not one of them defended him.

Not one.

A bitter smile touched his lips.

"So I've finally become useful."

The sentence was soft.

But it struck everyone harder than a shout.

---

Miles away...

The Jeon procession approached the capital.

Black horses.

Silver banners.

Rows of disciplined royal guards.

At the center rode Crown Prince Jeon Jungkook.

His posture was flawless.

His expression unreadable.

One knight rode beside him.

"Your Highness."

"What?"

"There are... rumors."

Jungkook didn't look at him.

"What rumors?"

"The princess may have disappeared."

Jungkook's horse slowed.

His jaw tightened.

"What did you say?"

"No one knows if it's true."

A dangerous silence followed.

"If this is another political game..."

His eyes turned cold.

"...they will regret it."

The wind lifted his black cloak as the procession continued toward the palace, unaware that the fate awaiting him was nothing like the marriage he had agreed to.

The palace gates of Haneul stood wide open.

Rows of soldiers lined the entrance in polished armor, their spears gleaming beneath the afternoon sun. Nobles filled the marble courtyard, dressed in silk and gold, whispering behind jeweled fans.

Everything looked perfect.

Only those inside the palace knew the truth.

The bride was gone.

And the kingdom was balancing on the edge of disaster.

---

The sound of horses echoed through the courtyard.

Thud... Thud... Thud...

"The Jeon delegation has arrived!"

Every noble immediately lowered their heads.

The massive black carriage stopped before the palace steps.

A royal attendant opened the carriage door.

First came the royal guards.

Then the commander.

Finally...

A pair of polished black boots touched the ground.

Jeon Jungkook stepped out.

He was dressed in deep navy ceremonial robes embroidered with silver dragons, a symbol reserved only for the Crown Prince. A sword rested at his waist—not because it was required for the ceremony, but because he refused to travel without it.

His expression was unreadable.

Sharp.

Cold.

His dark eyes swept over the palace with quiet precision, noticing every detail.

The stiff smiles.

The nervous servants.

The ministers who couldn't quite meet his gaze.

Something was wrong.

He could feel it.

His advisor, General Min, leaned closer.

"...Your Highness."

Jungkook didn't look at him.

"Speak."

"The atmosphere..."

"...is unusual."

"I noticed."

His voice was calm.

Too calm.

---

Inside the palace...

King Kim stood near the throne room entrance, taking a slow breath.

"This must not become a scandal."

A minister whispered anxiously,

"He'll find out eventually."

"Not before I tell him."

Another minister shook his head.

"He won't accept it."

The king closed his eyes.

"I know."

---

The grand doors opened.

Jungkook entered.

Every noble bowed deeply.

"Welcome, Your Highness."

Jungkook offered only a polite nod.

His eyes immediately found the king.

"Your Majesty."

King Kim stepped forward.

"Welcome to Haneul."

Their greetings were formal.

Respectful.

But strained.

After a brief exchange of courtesies, Jungkook spoke first.

"I would like to meet my fiancée before the ceremony."

Silence.

The king's fingers tightened around his sleeve.

"...There has been a complication."

Jungkook's expression didn't change.

"What kind of complication?"

No one answered.

His gaze slowly moved across the room.

One minister looked away.

Another swallowed nervously.

His instincts screamed that something had gone terribly wrong.

Finally...

The king spoke.

"Princess Sooyeon has disappeared."

The words landed like a blade.

For a heartbeat...

The room was completely silent.

Jungkook stared at him.

Then asked, very quietly,

"...She what?"

"She left the kingdom."

General Min's hand instinctively moved toward his sword.

Several Jeon soldiers tensed.

Jungkook remained perfectly still.

His calm was somehow more frightening than anger.

"I crossed three kingdoms."

"I negotiated peace."

"I agreed to this marriage despite having no desire for one."

"And now..."

His voice lowered another degree.

"...you tell me your princess ran away?"

King Kim bowed his head.

"I offer my sincerest apologies."

Jungkook let out a humorless laugh.

"Apologies?"

His eyes hardened.

"Do apologies prevent wars?"

The ministers flinched.

No one dared interrupt him.

---

Then...

The king said the sentence that changed everything.

"There is... another proposal."

Jungkook looked at him.

"My youngest child will take her place."

Jungkook frowned.

"I wasn't aware the princess had a younger sister."

"...She doesn't."

A pause.

"My younger child is Prince Kim Taehyung."

Silence.

Utter silence.

Even the servants stopped breathing.

Jungkook blinked once.

He was certain he had misheard.

"You expect me..."

"...to marry your son?"

"Yes."

For the first time since arriving...

Emotion flashed across Jungkook's face.

Disbelief.

Then anger.

A cold, dangerous anger.

"Am I a joke to your kingdom?"

"No."

"Then why am I being treated like one?"

King Kim didn't answer.

There wasn't an answer that could undo the humiliation.

Jungkook took one slow step forward.

"You invited my empire."

"You announced this alliance."

"You promised a princess."

"And now..."

"...you offer me someone else because your plans failed."

His voice echoed through the throne room.

No shouting.

No raised tone.

Just controlled fury.

Sometimes that was worse.

---

At that exact moment...

Outside the throne room...

Taehyung stood behind the half-open doors.

He hadn't intended to listen.

But the voices carried through the corridor.

He heard every word.

"...You offer me your son?"

Each sentence struck harder than the last.

Taehyung lowered his gaze.

He had expected resistance.

He hadn't expected to feel like a replacement before the man had even seen him.

One of the palace maids looked at him with pity.

"I'm sorry, Your Highness..."

Taehyung gave her a small smile.

"It's alright."

It wasn't.

---

Inside...

Jungkook continued.

"I refuse."

The room froze.

"This marriage ends today."

General Min stepped beside him.

"The Jeon Empire will return home."

King Kim's face paled.

"If you leave..."

"The treaty dies."

"Then it dies."

The words echoed through the chamber like a final verdict.

---

A soft voice interrupted.

"...Before you decide..."

Everyone turned.

The great doors slowly opened.

Taehyung stepped inside.

The throne room fell silent.

He wasn't wearing elaborate ceremonial robes.

Only simple white silk, still carrying faint traces of blue paint near one sleeve. His long dark hair was tied loosely at the nape of his neck, and there was nothing ostentatious about him.

Yet his quiet presence drew every eye.

Jungkook looked at him for the first time.

Their gazes met across the hall.

Neither bowed.

Neither smiled.

Taehyung spoke first.

"I didn't ask for this either."

Jungkook's jaw tightened.

Taehyung continued, his voice calm despite the tension.

"You were promised a bride."

"I was promised nothing."

A brief silence.

"But now we're both standing in the middle of a decision neither of us made."

Jungkook studied him carefully.

There was no fear in the prince's eyes.

No pleading.

Only exhaustion.

"I don't expect your sympathy," Taehyung said. "And I won't beg you to marry me."

Another silence settled between them.

Then Jungkook answered, his voice cool and unwavering.

"Good."

"Because I have no intention of making this easy for you."

Taehyung held his gaze.

"I wasn't expecting you to."

For the first time, Jungkook saw something unexpected.

The prince wasn't trying to win him over.

He wasn't pretending to be cheerful.

He wasn't acting like a sacrifice begging for acceptance.

He simply looked... tired.

And somehow, that unsettled Jungkook more than anger would have.

---

The throne room remained silent as the two princes faced each other.

Neither of them knew it yet.

But this was the first move in a battle that would take months to end.

And somewhere beneath the anger...

The first thread of an impossible bond had been tied.

The palace bells rang three times.

Their deep echoes rolled across the kingdom, carried by the evening wind.

To the people outside the palace walls, it was the sound of celebration.

Inside...

It sounded like a countdown.

---

The Prince's Chamber

Taehyung stood before a tall bronze mirror while attendants draped layers of ceremonial robes over his shoulders.

The fabric was heavy—black silk embroidered with gold phoenixes and white lilies, the royal colors of Haneul. A golden sash rested at his waist, and an intricate jade clasp fastened his collar.

One maid carefully adjusted his hair.

"You look magnificent, Your Highness."

Taehyung smiled politely.

"Do I?"

She nodded enthusiastically.

"You look every bit a prince."

He looked at his own reflection.

For a long moment, he said nothing.

"...I don't recognize myself."

The maid lowered her eyes, unsure how to respond.

Another servant entered in haste.

"The ceremony will begin in half an hour."

Taehyung dismissed the attendants with a gentle nod.

"I'll be there shortly."

When the doors closed, silence settled over the room.

He walked toward the open balcony.

Below, hundreds of lanterns illuminated the palace gardens. Musicians tuned their instruments, and nobles laughed together as though tonight were a joyous celebration.

Taehyung rested his hands on the cold marble railing.

"They're celebrating peace," he thought.

"Not knowing it's being bought with two unwilling hearts."

---

The Guest Wing

Jungkook was sharpening his sword.

The rhythmic scrape of metal against whetstone filled the room.

General Min watched from nearby.

"You'll ruin the blade if you keep sharpening it."

Jungkook didn't stop.

"It helps me think."

General Min sighed.

"You've hardly spoken since the throne room."

"What is there to say?"

"They deceived us."

"They did."

"And yet..."

Jungkook paused.

"...the prince."

General Min raised an eyebrow.

"What about him?"

"He didn't lie."

The general remained silent.

Jungkook continued.

"He looked just as trapped as I was."

He remembered Taehyung's calm voice.

"I didn't ask for this either."

There had been no manipulation.

No false tears.

Only honesty.

That unsettled Jungkook more than any scheme could have.

---

The Royal Hall

The ministers gathered around King Kim.

"Your Majesty," one whispered, "if Prince Jungkook refuses at the altar..."

The king's expression darkened.

"Then we will lose everything."

Another minister added,

"The Jeon Empire may see this as an insult."

The king closed his eyes briefly.

"I know."

He wasn't just afraid for the treaty.

He was afraid for his son.

---

The Corridor

Taehyung walked alone toward the ceremonial hall.

His footsteps echoed softly against polished marble.

As he turned a corner...

He stopped.

Someone stood at the opposite end of the corridor.

Jungkook.

For a long moment, neither of them moved.

Only the flickering candles between them danced.

Jungkook broke the silence first.

"So..."

"This is what they dressed you in."

Taehyung glanced down at his robes.

"I didn't choose them."

"I assumed as much."

Another silence.

The air between them remained tense, but no longer hostile enough to explode.

Taehyung spoke quietly.

"You don't have to go through with this."

Jungkook looked directly at him.

"If I leave..."

"...your kingdom falls."

Taehyung didn't deny it.

"And if I stay..."

"...mine loses face."

Neither answer was acceptable.

For the first time, they both realized something.

Neither was the enemy.

They were simply standing on opposite sides of the same trap.

---

The Ceremony

The palace chapel shimmered beneath hundreds of candles.

White flowers lined the aisle.

Nobles from both kingdoms filled every seat.

Soft music echoed through the vast chamber.

When Jungkook entered, everyone rose.

Moments later...

Taehyung appeared at the opposite end.

A ripple of whispers spread through the crowd.

"That's the prince?"

"He's beautiful..."

"But... he's not the princess..."

The whispers reached Jungkook's ears.

He clenched his jaw.

Not because they spoke about Taehyung.

Because they were treating him like a spectacle.

Taehyung walked steadily down the aisle, refusing to acknowledge the stares.

When he reached the altar, he stood beside Jungkook.

Close enough to hear his breathing.

Neither looked at the other.

---

The High Priest raised his hands.

"Today, two royal houses shall become one."

His voice echoed through the hall.

"Do both parties enter this union of their own will?"

Silence.

The question lingered in the air like a cruel joke.

Taehyung slowly lifted his eyes.

"No."

Gasps erupted throughout the hall.

The priest froze.

Jungkook turned sharply toward him.

Taehyung's voice remained calm.

"I do not enter this marriage by choice."

The hall fell deathly quiet.

After a long pause, Jungkook spoke.

"...Neither do I."

More whispers.

Some nobles looked horrified.

Others looked strangely relieved by their honesty.

The High Priest hesitated before continuing.

"Though unwilling..."

"...do you accept this union for the peace of your kingdoms?"

Taehyung closed his eyes for a brief moment.

"...I do."

Jungkook looked at him.

Then, with visible reluctance...

"...I do."

The priest nodded solemnly.

"Then before the heavens..."

"...I declare you bound by the same crown."

The ceremonial bells rang.

The treaty was sealed.

But no smiles appeared on the faces of the two princes.

---

Later That Night

The celebrations continued in the grand ballroom.

Music filled the palace.

Wine flowed freely.

Nobles toasted the new alliance.

Far away from the laughter...

Taehyung slipped quietly into the palace gardens.

The cool night air carried the scent of jasmine.

He finally allowed himself to breathe.

"You ran away from your own wedding too?"

A familiar voice came from behind him.

He turned.

Jungkook stood a few steps away, his ceremonial cloak draped loosely over one shoulder.

"I didn't run."

Taehyung replied softly.

"I escaped the noise."

Jungkook looked toward the glowing palace windows.

"...Good choice."

For the first time since they had met...

They stood together in complete silence.

Not as enemies.

Not as friends.

Just two strangers sharing the weight of a decision neither had made.

Neither noticed the shadow watching them from behind the garden hedges.

A cloaked figure tightened their grip on a hidden dagger.

"They've survived the wedding..."

The stranger whispered.

"...They won't survive what's coming next."
