This is about how zoro would be jealous of luffy if he were to spend time with robin.
Luffy ran to the kitchen as he shouted "robin! Rooobiin!"
Robin looked at the captain who was running to the kitchen. "Captain-san...?" She called out looking a bit confused. She then paused and stopped walking when she heard several crashing sounds of pots and pans from the kitchen. She sighed. The captain was making a disaster again. She walked into the kitchen and found a bunch of kitchen utensils and pots fallen on the ground. And beneath the pile of the pots and pans was their captain, luffy. "... captain-san..?" She muttered to check if he was fine.
Luffy popped out of the pile with a roar with his fist up in the air. "I'm okay! It's just..." he then quickly looked around and groaned. "Sanji's gonna kill me..." he quickly tried to stash everything in a cupboard but it poured out immediately. "Ah, robin. I was just trying to give you a cup of coffee but..."
Robins eyes trailed to where he was staring at. A broken cup of coffee on the ground. "Oh" was all she could say.
Luffy gulped. "You gotta promise me not to tell sanji that I did all of this. If he knows then hes gonna ban me not only from the fridge but the whole kitchen itself!"
Robin chuckled. "You can trust me." She said as she gathered the pans from the ground.
Luffy nodded. "Let's say... ano...usopp did all this." He said hurriedly.
Robin then silently eyed luffys hands and frowned. "You're hurt" she said as she laid the pots on the ground.
"Eh? Hurt? Where?" Luffy frowned confused.
Robin stood up and walked to her room and came back with a bandaid. "Look at your hand, captain." She held luffys hand which had a slight cut from the fall.
Luffy shrugged. " eh.. well... if sanji finds out, hes gonna give me more than a cut..." he muttered worriedly.
"find what out? I thought we agreed that usopp did all this." Robin smiled. "Didn't he?" She placed a bandaid on the small cut on luffys hand.
Luffy stared at robin then started to laugh out loud. "Robin! You're right! Usopp did all this mess!"
Zoro turned around the corner hearing the disaster from the kitchen as well. He then peered into the kitchen to check if anything was going on but frowned. There was luffy and robin holding hands on the ground. He then quickly turned around and walked away with a growl. What were the two doing there? Whatever it was, he didn't like it. It bothered him. The next morning was worse.
When zoro woke up he walked out to the deck but scowled when he saw luffy sleeping. But that was not the problem. The problem was that he was leaning against robin's shoulder while she was reading, not to mention the fact that he was almost drooling all over her shirt.
Zoro huffed and walked away again. When it was afternoon he followed luffy quietly and scowled when he realized luffy was going to robin again. Luffy looked around warily and whispered something to robin. It made robin laugh softly with a slight blush. Luffy was laughing too. Zoro then slammed the door shut so both of them could hear and walked away. He scowled and tried to calm down. Why was he feeling annoyed of luffy? He scratched his head. Maybe he should just forget about it. Just let all of it go.
It was night when zoro was in the crow's nest. He was just thinking about luffy and robin being all close all of a sudden. Zoro took a bite out of his onigiri and sighed. Thinking about the two together made him groan. He stuffed the onigiri into his mouth and munched madly. He heard someone come up and turned around and almost spewed pieces of rice all over the ground to see it was robin. He swallowed hard and just stared at her. "What, you came here with luffy or something?" He couldnt help but scowl.
Robin stared blankly at him. "Was i supposed to? I just came here because the captain said you had something to tell me." She said and sat beside zoro.
Zoro frowned. Why did luffy tell her that? He cleared his throat. "I thought you were having a good time with luffy with all the laughing and whispering... aren't you two ano... a little something going on between you two...?" He asked carefully.
Robin stared at zoro. "Whatever do you mean?"
"Like... um... don't you like luffy or something?"
Robin stared at him longer. She then chuckled as she reached out and wiped a piece of rice off of zoros shirt. "You have a wild imagination."
Zoro frowned looking really confused. "... but... how bout when you and luffy were holding hands in the kitchen?"
"His hand got cut from one of the knifes in the kitchen. I was putting bandaid on it." Robin answered.
"How bout when he was leaning on your shoulder in the morning?" He argued.
"I honestly believe you would've fallen asleep too if I were to read you a book called micrographia: its disorder and treatment."
"Then what about when luffy whispered something to your ears and you laughed?"
Robin sighed. "Do you really want to know, kenshi-san?"
Zoro nodded.
"He told me you were wearing red boxers with pink hearts." Robin said with a small chuckle. Zoro blushed while growling.
"The little bastard..thats not true..." he muttered but sighed. "so theres nothing going on between you two?"
Robin shook her head.
Zoro nodded. "That's good to hear."
"Is it?"
"... yeah."
Sorry that it was written quite messily. It was a suggestion so I wrote it for fun. I usually can't write good romance stories so I like to end things implied or hanging.
