Primal Instinct (Zosan)

one

Hello there! This fic is pure self-indulgence, just letting you know beforehand. Once I finished watching OP back in Spring, I was determined to write at least one multi-chaptered zosan fic, and then zosan + werewolves au popped into my head, so here we are, I guess! I hope you enjoy this fic just as much as I enjoyed writing it!

A/N: Luffy: Beta, Zoro: Alpha, Usopp: Beta, Nami: Alpha. No mpreg/heats/ruts. There is a mating season, but nothing like 'knots' or 'self-lubricating omegas' exist.

At this point, Sanji had given up completely on trying to figure out Zoro. That green haired dog was just impossible to fucking read! He barely voiced out his own opinions (only rarely when the situation called for it), and if he wasn't too preoccupied with his ridiculous daily training, he would either be sleeping or drinking like an alcoholic.

In short, Zoro and him had barely ever had a civilized conversation that lasted more than ten seconds without yelling profanities and trying to kill each other. Sanji doubted if Zoro cared about him in the slightest, as their bond consisted of a mere mutual respect for each other's skills in battle, but besides that, they hardly tolerated each other.

And then that green haired idiot goes and pulls shit like that when they were facing Kuma, throwing Sanji completely off the loop. Just what was his deal? He knows that Zoro isn't the type of guy to want to steal all the glory for himself and boast about it. In fact, that guy is probably the most honorable man Sanji has ever come across. It makes him absolutely sick just admitting it to himself, but still. Was it something more personal? Or was it just Zoro being an idiot?

Well, he wouldn't put it past Zoro to do that just to spite Sanji. They could both reach extreme levels of pettiness when it came to being competitive. Or perhaps it was a hero complex? From what he had observed since he first joined the crew, Sanji felt like Zoro was oddly overprotective of the people he considered to be his friends.

Willing to cut your own legs without a moment of hesitation to save your friends? Willingly accepting all the pain and damage Luffy sustained in his previous battles, just so the rest could walk free? It wasn't like Sanji wouldn't make any precious sacrifice to aid his friends in need, but any logical person would hesitate, would be scared.

But then again, Zoro never had any ounce of rationality in him, did he?

"Cook-san."

Sanji turned to glance over his shoulder, a wide smile spreading on his lips as he saw Robin approaching him.

"Ah, my sweet Robin-chan, to what do I owe the pleasure of your visit? Are you perhaps hungry? Thirsty? I could—" as he was about to stand, a hand emerged from his back, gently applying pressure on his shoulder.

"Thank you for your offer, but we're all good for the moment, cook-san. I merely came to check on you, as you've been sitting here for a couple of hours now and we were starting to get worried." Robin explained as she came to stand beside him, staring at the dark sea stretching in front of them.

Sanji clasped his hands together, "Ah, I apologize for getting my two sweet angels worried about me, that was not my intention, Robin-chan! I just came out here to clear my mind and didn't notice when time passed by." He responded.

Robin turned towards him, head cocked slightly to the side, "And what exactly would be preoccupying your mind so much that has made you lose track of time?"

Sanji waved his hand, smiling up at Robin. "Oh, it's nothing important, I don't want to waste your precious time—"

"Cook-san," Robin interrupted, "I assure you; you are not wasting any of my time. While not much unusual, it's odd to see you so hung up on something."
