This one is an AU, has no ships, and it slightly Sanji-centric.

He was being scolded. He hated being scolded.

To make matters worse, it wasn't even his brother or Brook scolding him. It was Usopp, the fucking long-nosed guy who was just a friend of his brother. What right did this asshole have to scold him?! In his house?! He'd just gotten home from school and suddenly this dipshit started-

"Sanji, are you even listening?"

The little blond glared up at the older male through his bangs with as much malice as he could muster, completely despising him at the moment for ruining his good mood. It was a Friday and he'd just gotten home from school! "Why should I?" He lifted his head, the anger in his eyes intensifying. "You're not the boss of me!"

Usopp narrowed his eyes in irritation, before rolling them and pointing a stern finger at the little chef-to-be. "For one Sanji, I'm older than you."

Sanji opened his mouth to speak, but wasn't able to say anything as his best friend - who had been standing behind him - had decided to talk. "Ace said that just 'cause someone's older than us, it doesn't mean they have authority."

"Shut up, Luffy."

"But-"

"Shut up."

The teenager glared the smaller brunette down for a moment to make sure he wouldn't continue, then turned his gaze back to the blond. A sigh escaped his throat as he covered his face with his palm. "Sanji, look; all I'm saying is that you shouldn't swear. It's not a good habit and you're still just a ki-"

"I'm twelve!"

"Twelve is still just a kid!" There was an awkward pause of silence as Sanji attempted to burn a hole in Usopp with his glare, and the teen just shook his head. "I don't even understand where you learn these words..." He honestly didn't. The first thing out of the little blond's mouth when he had walked in the door (said thing having apparently been directed at Luffy) was 'You dipshit'. Where the hell had the blond even heard that word?

"Zoro says them all the time."

As the kid spoke, Usopp's head snapped up immediately. He studied Sanji's annoyed expression for a moment. "What?"

"Zoro swears all the time." The little cook-in-training crossed his arms over his chest and huffed. "Brook never scolds him for it so why am I being scolded!"

"Okay, Sanji," The older male found himself sighing yet again for what felt like the thousandth time in only the past five minutes. "Just because you're brother is swearing, that doesn't make it okay for you to swear."

"Yes it does!"

"Sanji-"

"Zoro! Usopp's saying I'm not allowed to swear just because you do!"

Ah, and now the kid was trying to get his big brother to defend him. Well it wasn't going to work; Usopp knew his friend well enough that he wasn't going to just side with Sanji on th-

Zoro's voice was suddenly heard from a few rooms over, his tone sounding entirely serious to anyone who didn't know him. "I don't fucking swear!"

-is... Really?

Sanji just giggled and grinned triumphantly. "I win!" He didn't give the self-proclaimed sniper a single second to yell at him again before he ran off, his best friend trailing closely behind him.

"Wai-" Too late, the little shit was gone. Usopp's expression turned to a scowl and his gaze turned to the hallway just in time to see Zoro come out of it, and thus he fixated his glare on him.

"What?" was the moss-haired idiot's only response; followed by a knowing smirk that ceased to do anything but taunt his friend.

Continuing to just glare at him, the darker-skinned teen grit his teeth. "I hate you."
