Lunch
Sanji made lunch an art form. Every movement was perfect, every ingredient added, every swirl of the spoon, the temperature, everything had to be exactly right.
Usopp was accustomed to watching Sanji cook from where he sat on the opposite side on the galley. He had always been a fan of art, why not watch Sanji do what he does best?
The sniper admired Sanji for his skill with his hands, and for what he could do with food.
In a way, Sanji spoiled the crew of the Going Merry. They'd never had things like sandwiches, salads, soups; everything Sanji made was gourmet, everything was more delicious than the last.
Sanji was happy to have the silent company of Usopp while he cooked, and every once and a while he had the chance of listening to the sniper hum to himself while he worked on his latest upgrade.
The two bonded over lunch.
The afternoon got to be uneventful, and while Luffy bugged Zoro, Nami worked on their course, Chopper mimicked Luffy, and Robin watched, the two were in the galley together.
Sanji preened every time Usopp would make some noise of admiration, even if it was only to himself; and every once and a while Sanji would turn his head momentarily to comment Usopp on a painting, a new weapon, or whatever else he was working on at the time.
Lunch became a routine for them. While Sanji cooked, Usopp would continue to work on his latest projects, and by the time the two had exchanged their compliments, lunch was done.
So Usopp was thrown when he walked into the galley for lunch and Sanji was nowhere to be found. He assumed that since everyone had gone to shore, he hadn't bothered to cook, but that just wasn't like Sanji.
On his way out of the galley, Usopp was stopped by a black sleeved arm. He felt a plate push into his stomach slightly before he actually looked up.
"Here." Sanji's eyes were hidden by hair, his head turned away from the sniper.
"What's-"
"I made it for you...for lunch." Usopp was shocked, but took the plate slowly and looked it over.
Everything was prepared perfectly, like Sanji always did for the crew, but this time it was solely for Usopp.
"It's not poisonous." Sanji said irritably, "There aren't any mushrooms. Just eat it." Usopp had to smile, the sentiment was definitely appreciated, and upon taking a bite Usopp was convinced: Sanji was, quite possibly, the best cook on the blue seas.
Seeing Usopp's face brighten was enough for the cook.
"You're welcome." Sanji gave Usopp a smirk, and left the ship once more.
It never really dawned on Usopp before, but maybe Sanji's cooking was his way of showing affection, his way of saying: "I love you."
