🌊 Scene One: The Letter

Fuma found the first note pinned to a tree just outside Port Miren.

Burnt at the edges. Sealed with wax. Written in elegant, mocking cursive:

"Closer this time. I could feel your boots hit the sand.
Let's not pretend we don't enjoy this."
— K.

Fuma crushed the paper in his hand.

He had been chasing the infamous Captain K for three months. The bounty was staggering. The trail was erratic. And K?

K was toying with him.

🗺️ Scene Two: The Tavern

Fuma almost didn't recognize him.

The tavern was loud, smokey, pulsing with music and lies. And then—
There he was.

K.

Back turned. Coat draped over one shoulder. A drink in his hand, untouched.

Fuma didn't draw his weapon.

Not yet.

He slid into the seat beside him.

"Bold of you to stay in one place."

K smiled without looking at him.

"You always find me."

"Maybe I'm just good."

"Maybe I want to be found."

That made Fuma pause.

K finally turned his head—eyes sharp, smile lazy, like he already knew how this night would end.

"Tell me, hunter. What will you do when you catch me?"

"Tie you to the mast. Drag you to the Council. Let them decide."

"You won't."

"Won't I?"

"No," K said, leaning in just enough to feel dangerous. "Because I don't think you chase me to end it. I think you chase me so you don't have to go back."

Fuma stood.

Too fast.

"Enjoy your drink."

"Enjoy pretending you're still the one in control."

⚔️ Scene Three: The Catch

It happened on the cliffs above Seabreak Point.

Fuma finally cornered him—sword drawn, wind howling, waves crashing below.

K just stood there, arms half-raised like wings.

"I'm unarmed."

"You're never unarmed."

"You came alone."

"I wanted it to be me."

A beat.

"You came alone," K repeated, stepping forward.

"Don't," Fuma warned, but didn't move.

"You never needed the bounty."

"I need to end this."

K smiled—almost gentle this time.

"Then end it."

He dropped to his knees. Threw his coat to the side. Exposed his chest to the blade.

"Take me in."

Fuma raised the sword.

And held it there.

Frozen.

K looked up at him. All fire, wind, and surrender.

"What will you do, hunter?"

"...Why are you letting me?"

"Because I want to see if you'll still look at me the same after."

Silence.

Then—

Fuma dropped the sword.

Grabbed K by the collar.

And kissed him like he'd been dying to for a hundred years.

⛓️ Scene Four: The Aftermath

K lay on the floor of the holding cell aboard Fuma's ship.

Fuma sat outside the bars, head in his hands.

K was humming. Always humming.

"You're not going to deliver me."

"Don't be so sure."

"You kiss like someone who's already mine."

Fuma didn't answer.

But he didn't move away either.

"Tell them I escaped," K offered, eyes gleaming. "Say I overpowered you. Or you made a mistake."

"I did make a mistake," Fuma muttered.

K leaned against the bars.

"So what now?"

Fuma looked up at him.

Slow. Steady.

"Now I decide if I want to be the man who turns you in... or the one who lets you turn me into something else."

K (softly): "What am I worth to you, hunter?"

Fuma: "More than a bounty."

K: "Then open the door."

And Fuma did.

🏴‍☠️ Scene Five: On the Run

They escape at night.

No fireworks. No dramatic duel. Just a rowboat, a stolen map, and silence so tight it buzzes.

They dock at a half-buried cove in the Isles of Mire.

The water is warm. The beach is empty.

Fuma doesn't sleep.

He watches K across the firelight, cloak pulled tight, back against a stone, already half-dozing like he belongs to the dark.

And maybe he does.

Fuma sharpens a knife. Doesn't need it sharp. Just needs something to keep his hands from shaking.

"You keep doing that," K says, eyes still closed, "like you're preparing to stab me or kiss me again."

"Both are still on the table."

"And yet, here you are. Still running with me."

Fuma throws the knife into the dirt, blade first.

"I had a code."

"You still do. It just shifted."

"That's not better."

K finally sits up, the firelight painting gold across his face.

"You're allowed to change."

"I wasn't supposed to want any of this."

"You wanted me." K says it plainly, without pride.

"You knew it from the start."

K smiles. Not the smirk. The real one—smaller, quieter, and devastating.

"I knew it before you did."

🕯️ Scene Six: Flashback — Before the Chase

Years earlier. Another harbor. Another port.

K leans against a rail, cloak up, hood shadowing his face.

He's watching the bounty boards.

He's watching him.

Fuma, clean-cut and sharp-eyed, pinning up his newest capture. Collecting gold, nodding once to the guard captain. Efficient. Controlled. Untouchable.

"What's the verdict?" someone asks behind K.

"Dead or alive," K replies. "Same as always."

He doesn't look away.

"And?"

"Alive," K murmurs. "But only if I'm the one he catches."

He tears the poster down later. Leaves a different one in its place.

His own name. His own bounty.

Raised. Higher than it's ever been.

Just to make it worth the chase.

🌌 Scene Seven : Now, in the Firelight

Fuma watches K stretch out beside him in the sand.

One arm over his eyes. At peace.

And Fuma realizes:

He's not breaking his code.

He's rewriting it.

Fuma: "You let yourself get caught."

K: "I never let anything happen.
I chose you."

🗡️ Scene Eight : The Final Mission

A notorious arms dealer—once an informant for the bounty council—now rogue. Dangerous. Slippery. The kind who leaves no witnesses.

They say he's holed up in a fortress off the Obsidian Coast.

They say no one can get in.

They clearly don't know Fuma in black and K with a smirk full of secrets.

Fuma walks into the stronghold dressed like death itself.

No badge. No title. Just black leather, two blades, and quiet rage.
K lounges beside him, sleeves rolled, spinning a stolen coin, already charming the guard with a crooked grin.

"You're sure we're not here to kill him?" Fuma mutters under his breath.

"I never said not to kill him. I just said I'd distract."

Fuma disappears into the shadows.

K steps forward, all silver tongue and smile sharp enough to wound.

The guards don't stand a chance.

They take down the dealer in under twelve minutes.

K doesn't draw a weapon.

Fuma doesn't miss a step.

By the time the place is burning behind them, neither looks back.

"That felt final," K says.

"It was."

"Then what now?"

Fuma just reaches for his hand.

"Now we disappear."

🏝️ Scene Nine: Island Life

It's quiet here.

Waves lap at the dock. Bread rises in the mornings. K always forgets to bring in the laundry before it rains.

They fix up an old house with sea glass windows. K fills the bookshelves with maps of places they'll never need to run to.

Fuma starts drawing again.

Most days, no one bothers them.

Until one doesn't.

A ship docks.

A man steps off, polished boots, crisp coat, parchment in hand.

He walks up to the little house.

K sees him first.

"He's asking for you," he says. Voice low.

Fuma puts down his fishing line.

The man removes his hat.

"You're the hunter, aren't you?"

"Not anymore."

"They say you helped a pirate disappear. That you went rogue."

"They say a lot of things."

A pause.

"You could come back. Wipe the slate. Be who you were."

Fuma looks past him—where K leans against the doorframe, watching. Quiet. Waiting.

Fuma smiles, slow.

"I don't want to be who I was."

He steps back. Closes the door.

Locks it.

K doesn't say anything.

He doesn't have to.

🌊 Final Line:

Fuma walks past him, brushes their shoulders.

"You gonna say it?" K asks softly.

"Say what?"

"That you stayed for me."

Fuma turns, finally looking him dead in the eyes.
"No," he says. "I didn't stay for you.
I stayed for us."

And K—pirate,lover, legend—smiles like the sea itself is listening.
