The sun was just rising when Sanji made his way to the deck the next morning. Nami had kept watch the night before and was leaning against the railing, wrapped in a thin blanket and looking out onto the blue horizon. She turned when she heard his footsteps on the wooden deck.
"Good morning Sanji"
"Good morning Nami-swan. Would you like some coffee?"
"That would be wonderful."
Dating or not, Sanji still pampers his ladies. Old habits die hard. It leaves Zoro torn between amusement and irritation. He's toned down his affection a little, no longer doing what his swordsman has dubbed "his best noodle impression" whenever they speak to him, but if the rest of the crew noticed, they haven't said anything. He makes his way to the galley to prepare the navigator's drink. When he goes back to the deck, tray balanced on one arm with a cup of coffee and a few slices of buttered bread arranged artistically on it, he finds her in the midst of an argument with Zoro.
"There's no way! I'd have noticed if that were the case!"
"I'm telling you, we're approaching a winter island."
"Would you be willing to bet on that?"
Zoro narrowed his eyes "What kind of bet?"
Nami thought for a moment "If you win, I'll decrease your debt by ten percent. If I win, I increase your debt by twenty percent."
"Deal."
They were dangerously close now, and Nami looked about ready to cloud the swordsman on the head. Sanji decided to intervene, since he preferred his boyfriend sans concussion.
"Che, marimo, I leave for ten minutes and you already start a fight with Nami-swan? Go train or something."
Zoro rolled his eyes and stalked off to the crow's nest, Nami drank her coffee in relative silence, and the argument was forgotten.
That afternoon, Sanji was on the deck enjoying the cool ocean breeze and Zoro was lying propped against the nearest wall, taking a nap. The swordsman felt a dark shadow fall over his face, and lazily opened one eye. Towering over him with a truly irritated look on her face, was Nami.
"Your debt is cut by ten percent." she grit out, looking mutinous.
Zoro raised an eyebrow. He could see Sanji smirk out of the corner of his eye and grinned a little, and turned his head towards him. The cook winked.
Nami cleared her throat.
"You wanna take a guess on how far away it is? Double or nothing?"
"Not on your life!"
A/N- So the Nami-Zoro bet had been floating around in my head almost before I wrote the fic, and then someone commented something about Zoro realizing about the island before even Nami, and this happened. It's short, but I hope you like!
