Here is U! The idea for this one popped into my head when I was concocting a whole different U version, it was going to be Universal -Summary: Love is one language understood around the world.- it was going to be an AcexLuffy story. They weren't going to be related and were gonna be pen pals! But yeah this one domminated my brain and kicked Universal out of the window, it flew rather far. By the by this oneh is a ZoroxLuffy.
Summary: Because they didn't make promises they couldn't keep.

The handful of people that actually knew of their relationship wondered how it would work, they both were dangerous men. Men that you didn't want to cross, men that had the means to have you killed in thirty minutes or less. Luffy was part of the Mafia, a Don to precise. He led the Mugiwara's who were notorious for their bipolar actions. Showing mercy to a man one day by letting him see his family another day, then the next having police find the same man with a slit throat and the Mugiwara symbol etched into his forehead. Zoro on the other hand was a mercenary; he could be hired to kill anyone for the right price. He was wanted in several countries all of which would immediately give him the death penalty. Both of them could be ruthless if needed and both were entrenched in the underworld where backstabbing and assassinations were the norm. Both had killed without blinking an eye and both wouldn't think twice about killing again.
When they were asked why they thought it would work, why they would be able to stay together, why they would be able to never turn against each other they both gave the same answer. They hadn't promised each other anything. They didn't sugarcoat things, they both knew what kind of person each other were, they were people that could survive in the darker corners of humanity and flourish.
They hadn't made any promises that would later be broken; they hadn't promised to not betray each other. Zoro would relieve Luffy of his head in a second if give the right amount and Luffy would crush Zoro if the green haired man ever overstepped his bounds.
"You know I'll kill you if you hurt any of my nakama, right?"
"Ai. And you know I'll cut you down if I'm hired to?"
"Of course! I wouldn't expect anything less."
They hadn't promised not to hurt each other. In fact they did that daily. It hurt Zoro to see Luffy tormenting himself by staying in the background while his family fought and Luffy was hurt everyt so often by Zoro's callous comments.
"I'll hurt you."
"Shishishi, I know. But I'll end up hurting you to so it's okay."
They hadn't promised that the relationship would last. In fact they both had a firm belief that if it did go past the one year mark one of them would end up dead in a matter of days. Zoro thought because by that time one of Luffy's enemies would of heard about their fondness for each other and would use him to get to the Don. While Luffy was sure that Ace would kill Zoro to stop him from blabbing their secrets to unsavory ears.
"We probably won't last long."
"Eh, whatever. I'm not looking for a long lasting relationship, were doing this because we click."
"Hmmm…"
But even without those promises, without those vows that most would make they still held together, They survived through the years their friends making jabs at the fact that they'd been together so long that they could practically be married. When they heard this they would both snort and comment on how they weren't looking for a long term thing which would cause their collective precious people to burst into laughter.
"I won't promise you the world but I can give you my heart."
"That's all I need from you."
