You’d been sailing with the Straw Hats for a while now—long enough to be part of the chaos, the family, and the madness. So when the crew docked on a quiet little island for supplies, it felt like a well-earned break.

You were standing near a market stall, chatting with a local guy who was being… a little too friendly. He kept leaning in, smiling, and dropping compliments like he was auditioning for the role of “Island Boyfriend.”

“You’ve got a real nice smile,” he said, touching your arm lightly. “You’re not from around here, huh?”

You laughed politely, trying not to be rude. “I’m just passing through.”

From a distance, Luffy had been watching. At first, he was just munching on meat and looking around. But then he saw it—that guy, touching you. Laughing with you. Standing too close.

And something twisted in Luffy’s stomach. A weird, hot, uncomfortable feeling.

“What’s wrong with him?” he muttered, face scrunching up. “Why’s he leaning so close?”

Nami glanced at him. “You good?”

“No,” Luffy said flatly.

Before anyone could react, Luffy was already moving. He stormed up to the stall with that dead-serious look he rarely wore. You turned just in time to see him appear at your side.

And then—with no hesitation—he grabbed the guy by the collar and shoved him back a few steps.

“Hey!” the guy yelped. “What’s your problem?!”

“She’s with us,” Luffy said, his tone blunt, eyes locked on the guy. “Back off.”

You blinked. “Luffy—?”

He didn’t look at you. His jaw was tight, arms crossed, tail of his straw hat fluttering in the breeze.
