You were supposed to be relaxing. That was the plan.

A peaceful afternoon on the sands of Fishman Island. Just you and Fukaboshi. No Luffy accidentally declaring war on someone. No Zoro getting lost. No Sanji turning into a nosebleed geyser.

Just shells. Sunlight. Maybe some hand-holding.

But no.

Because somewhere between “let’s go shell collecting” and “whoever finds the rarest shell wins,” the Crown Prince of the Ryugu Kingdom had decided this was combat.

“Twenty-seven shells and counting!” Fukaboshi shouted triumphantly, holding up a glimmering blue conch like it was the One Piece.

You scowled. “You tackled me for that last one.”

“You hesitated. The battlefield shows no mercy.”

“I blinked, you lunatic.”

“You blinked slowly.”

You hurled a clam shell at him. He caught it with one hand, smirked, and added it to his basket.

This had all started when the Straw Hats returned to Fishman Island for a celebratory visit after the chaos with Hody Jones. Fukaboshi had offered to show you around. You—being the only Straw Hat who actually knew how to relax without causing international incidents—agreed.

It was just supposed to be a beach stroll. Maybe a little flirting. Very light competition.

But you forgot one crucial fact:

Fukaboshi was insanely competitive. Even in a calm, handsome, princely way.

You’d said, “Let’s collect shells!”

He heard: “Let’s engage in psychological warfare, armed with nothing but beach debris and sexual tension.”

Now you were knee-deep in a tidepool while your royal date was wrestling an octopus to get to a rare cowrie.

“Fuka—babe, please,” you said. “That mollusk looks pissed.”

“I’m not afraid of a cephalopod,” he grunted, prying the shell free.

The octopus slapped him with a tentacle and slithered off in a huff.

You stared.

He held the shell up triumphantly. “Worth it.”

You sighed and tossed a coral chunk into your bucket. “I’m going to tell your brothers you lost a duel with a sea pancake.”

“They’ll understand.”

“No, Ryuboshi will write a song about it.”

“He would, too.”

You flopped onto a rock to eat the snacks Fukaboshi had packed—sweet kelp rolls, bubble-fruit, and some very smugly presented coral chips “for champions only.”

“Do you get like this during formal events too?” you asked, nibbling.

“Only when I care about the outcome.”

“Oh? And you care about shell collecting?”

“I care about beating you at shell collecting.”

You rolled your eyes but couldn’t stop smiling.

He noticed.

“Admit it,” he said smugly. “You’re having fun.”

“No,” you said flatly. “This is miserable.”

“You’ve been smiling for an hour straight.”

“That’s because I’m hallucinating from heatstroke.”

“Romantic heatstroke,” he corrected.

You snorted, nearly choking on your snack.

The chaos escalated when Luffy showed up.

“WHOA! Are you guys FIGHTING?!”

Fukaboshi and you exchanged a glance of pure dread.

Before either of you could speak, Luffy had launched himself into the tidepools, shouting, “I WANNA HELP Y/N WIN!”

Fukaboshi froze. “That’s illegal.”

“THERE ARE NO RULES!” Luffy cackled, slapping at the water like a hyperactive seal.

From a distance, you heard Nami shout, “DON’T ENCOURAGE HIM!” and Sanji yell something about “shells of love.”

You sighed and palmed your face.

Fukaboshi leaned over and whispered, “We need to relocate.”

“Agreed. Before he brings a sea king into this.”

Eventually, you found a quiet spot away from your crew’s chaos. Just you, Fukaboshi, and the sound of gentle waves lapping against coral sand.

You crouched by a tidepool and picked up a pink scallop. He leaned over your shoulder, the heat of his body warm even through the water.

“That’s a nice one,” he murmured.

“Better than anything in your bucket.”

“I disagree.”

He nudged his collection closer.

Your jaw dropped. “You have forty. Are you building a shell throne?”

“Yes,” he said seriously. “So you can sit beside me.”

You blinked.

“Oh,” you said, voice small.

He smiled. “Caught you off guard?”

“Just didn’t expect my boyfriend to flirt mid-shell war.”

“I contain multitudes.”

Later, as the sun filtered down through the water above, casting rainbows through the kelp canopy, you both sprawled out on the sand.

Tired. Salty. Happy.

“I think it’s a draw,” you said, yawning.

“No way,” he said. “I clearly won.”

“You got slapped by an octopus.”

“You fell into a crab pit.”

“You pushed me into it.”

“It was a tactical move.”

You threw a shell at him. He let it hit him in the chest and then dramatically collapsed like you’d slain him in battle.

You scooted closer, nudging him. “Still breathing?”

“Barely. Your power overwhelms me.”

You chuckled and rested your head on his arm. “Thanks for today.”

He turned to look at you, expression warm.

“Thanks for coming back,” he said quietly. “Fishman Island feels brighter when you’re here.”

Your heart did a little somersault.

“…You’re just saying that because I beat you at shell collecting.”

“You wish.”

You kissed his cheek, salty and sun-warmed. “Rematch tomorrow?”

He grinned. “I’ll bring blueprints for our shell fort.”

You laughed. “I’ll bring Luffy as a distraction.”

“Unfair.”

“All’s fair in love and mollusks.”
