First I want to say that this fanfic was an idea I took from an unfinished fanfic titled Without you by bitter-CAnDy-sweet and I want to give him/her the credits for this story. The first chapter will almost be a copy of the only chapter of that fanfic (atleast half of it) but the problem of this story will be different because Luffy's reaction will also be completely different from that story.

Pairing: Luffy/Nami. Post timeskip

Disclaimer: I don't own One Piece nor half the contents of the first chapter.

I want you to smile

"Okay guys, we need to re-stock the ship while we're here so don't go messing around before that," ordered Nami eyeing each of the other members of the Straw-hat crew, "I will give you enough money to buy what we needs and nothing else, understand!"

"Stingy witch," said Zoro under his breath.

"What was that, Marimo?!" growled Sanji "How dare you speak of Nami-san like that!"

"I'll say whatever I want," interjected the swordsman turning away from Sanji, "shitty love-cook."

"You bastard! Apologize righ…"

Nami stood above a dazed Zoro and Sanji with large bumps on their heads. "That's enough! Zoro, as payment for that comment you're not getting any money from me," declared Nami as she walked around handing money to the rest of the crew members. "Now get moving and be back before sunset!"

"Yes, Nami-san!"

"The hell!"

Franky walked to the swordsman. "Oi Zoro! If you help me re-stock the ship, I can give some money. It's going to be though if I have to transport barrels of Cola and wood alone. Usopp is coming too." Zoro grinned and followed them while Sanji was heart-broken after being rejected by the girls and was now stuck with Brook.

The island they've reached is called Taki island. Tree covered the dome mountain and many waterfalls can be seen on the other side of the island. The island possessed a relatively large population despite having only one city and they looked like they loved this green and beautiful island.

The young navigator watched as the others walk off in the island to the city except for Chopper who has volunteered to watch the ship since his stock of medicine is still full. They were doing well in the New World and nobody could hurt them since their last stop. They were beating easily each crew that dared to hinder their adventures so there was not much to buy for him besides books but Robin will already buy some new ones for him. Nami began to make her way down the trail before she was startled by a soft tap on her shoulder. Nami turned with pleasant surprise to find her captain grinning at her as she sighed at the sight. An odd sense of relief and delight overwhelmed her when she was face to face with Luffy and she had to admit, she loved that smile but nobody had to know that. "Luffy, I thought you ran off with the others already. What do you want?"

"Oi Nami, you didn't give me any money," complained the younger boy.

"I know. You're just going to spend it on meat or something useless so you don't get any." Luffy pouted at her response looking with puppy-eyes at her in hopes of a change of heart. The girl tried to ignore him but she couldn't help falling for that cute face he was making for her. Nami was no match for his wide-eyed gaze as she quickly caved into him handing over a few berries. "Fine, but only for this one time."

" Shishishishi, thanks Nami!" cheered Luffy waving as he ran ahead of her. Nami watched his figure disappear in the city. She sighed again and followed him smiling at the butterflies still present in her stomach.

….

"Hmm… I'm still hungry. Nami didn't give me enough money…," whined the starving boy as he walked aimlessly through the city. He looked longingly at the street vendors on the side with the smell of stir-fry and barbeque tempting his stomach. Luffy looked around him searching for any of his nakama hoping for a little change to buy more food but the area was so crowded that it would be impossible to spot any of them.

The town was full of people mostly walking through the streets who seemed extremely friendly to him. They all knew Luffy like the rest of the world and they were friendly to him because this island was a former territory of Whitebeard. As someone who fought along with the pirate that protected them under his name and as someone who was the little brother of the 2nd division commander, Luffy was popular through the town and its people. He didn't mind how friendly they were as he got free shish kabob as a gift. Soon enough he managed to make several acquaintances in a matter of hours.

"Well, I gotta go find my friends. See you around," said Luffy to a bunch of kids and young women who were looking at him like the hero of the island. The straw-hat captain started walking casually walking with the back of his head on his hands. He looked up at the clear sky to get away from the crowds around him simply taking in the blissful weather that blessed the island.

"Haha! I know, it's not the easiest thing to deal with."

Luffy turned his to the familiar voice a couple of feet away from him. Following the direction he heard the voice, he found his way to a small sit-down restaurant. Quickly running up to the store he saw the distinct orange hair of his navigator through the open window as he excitedly jumped through the door. "Hey Na…"

Laughter drowned out his voice as he walked in through the door to find his navigator already had company. Nami was sitting with her back to him at a table with a group of young muscular men who seemed to be getting really intimate with her. "Wow, this guy sounds like a real card. Why are you even traveling with him?" one of the men asked.

"Heh…Well you know, the Grand Line was already a dangerous place. The New World is even worse for a girl like me and he's perfect for protection," stated Nami "my captain is a complete idiot."

Luffy stopped in his tracks and stared at Nami's back in disbelief at what he was hearing.

"I always tell him how stupid he is but he thinks I'm kidding all the time because he thinks we're nakama."

"Such a conniving beauty we have here," mused another man, "hey, why don't you dump your current crew and join us?"

"Oh, I would love to, but first let me tour your ship before I consider joining." The men laughed as they stood up laying money on the table to cover the bill. One of the guys looked up at Luffy who was standing close with his hat shadowing his eyes.

"Hey kid, what the hell do you think you're looking at?"

Nami lazily looked up at the half threatening glare of the man and followed his gaze from behind where she was sitting. Her heart skipped a bit when she saw Luffy standing there, with half lidded eyes, looking so serious and intimidating that she could have thought that it was another person. He watched her turn in her seat and the surprise all over her face when she saw him. "Luffy!"

"Is this the guy you were talking about, babe?" asked another man, "we can make the choice easier on you for which crew to pick."

"No!" exclaimed Nami with her eyes still on her captain startling the man, "Luffy, what did you hear?" She stood slowly and took one step towards him. "Luffy, I didn't mean any…"

"Wait a minute! You mean that guy is Straw-hat Luffy?!" another men said with fear and sweat running down his face.

The other guys of the crew were looking shocked and one of them stumbled on the floor when they took a step back."Y-y-you mean you were in the crew of Straw-hat Luffy?!"

Luffy glared at them and the people who looked at what was happening saw the men drop unconscious on the floor, foaming from their mouths.

"Quit screaming your heads off," Luffy said quietly but in a way that showed them who was superior. "You're hurting my ears."

Nami felt her legs becoming weak and fell, sitting on the floor. It was the first time she sensed Luffy intimidating her with his haki. It seemed that he did it unconsciously but it was enough to bring her down. If he really wanted to knock her down, she would be lying on the floor with these guys.

She looked at him from where she was sitting and she could see his eyes causing a lump formed in her throat. Hurt? Anger? Hate? She couldn't decide what it was that she saw in his eyes. She reached an arm toward him in her weakened state but saw him turn around and walk in the crowd with his hands inside the pockets of his short.

"Luffy…," she whispered in hope for him to come back.

"Luffy!" screamed Nami trying to stand up.

"Nami?! What's going on here?" She looked behind to find Robin with Zoro, Franky and Usopp.

"Hurry up and call Luffy back! Please…," she whispered the last part as tears start coming down her face.

"Tell us what's wrong," said Robin as she helped Nami move in a less crowded place.

How was it? I know I even copied sentences and all but since it's just my second fanfic and I kind of liked that writing style, I tried to use it for my own improvement. And I'm the type that improves by looking at the work of others but there are things that I can't learn without copying. If you think a serious Luffy is difficult to imagine, watch the film Z and more precisely at the scene after Luffy speaks with Kuzan/Aokiji. When he knocks down the marines with his haki and when he was thinking, just before that, is the perfect example of a serious Luffy. Don't try the one with suit in Strong World, it will be difficult to see him in normal clothes ^^

For the genres, I decided to make Romance and family because Angst or Hurt/Comfort can mislead your understanding of my story.
