Smile!

Luffy perched on the railing of the upper deck in front of the kitchen, overlooking the lawn below as he waited for his afternoon snack. He savored the warm rays of sunlight that kissed his face through the clouds and the soft, sea-salt scented breeze that fluttered through his hair.

It would have been a perfectly beautiful day if not for Law sitting there below him making him doubt his judgement. Law had just propped himself there, eyes closed, back was to the mast, scowl stretched across his lips. Something about that grumpy look on his face felt terribly out of place. How could anyone look so down on a day was pretty much custom-made to bring happiness?

"Torao never smiles- not big, happy smiles anyway," Luffy commented agitatedly. "It's not natural."

"You're not natural," Usopp noted from behind him.

Nami giggled from her spot next to their sniper. "Maybe Torao's mind is just deep in thought," she suggested.

"Or Torao-kun could be contemplating what it would be like to be torn apart by sharks," Robin asserted with a gleam in her eye.

"Robin!"

"Torao should just stop thinking if it makes him so unhappy," Luffy decided. His own smile had converted itself into a pout from thinking too much about one unpleasant thing. He considered following his own advice, but this was his Torao they were talking about and he was important.

"It seems alright if he's thinking about how to take down the next yonkou," Zoro cut in, making his way up the steps.

"I still don't like that Torao never smiles." Luffy continued to eye Law from across the ship as his crew helped him contemplate the matter.

"Well maybe he's just not happy- simple as that," Sanji surmised, catching their conversation as he pushed through the kitchen door to deliver a tray of vanilla and mikan flavoured ice creams dipped into big, hearty bowls.

"Ice cream!" Luffy cheered. "Thanks, Sanji! You're the best! This will help make Torao happy for sure." He grabbed up bowl of ice cream in each hand and leapt down onto the lawn. He strode over to where Law sat to stand in the sun, casting his shadow over the grumpy surgeon.

"It's your lucky day, Torao~" Luffy sing-songed, "Get ready to smile, 'cause we've got icecream~"

Law looked up at him, his sullen expression unwavering. His eyes moved slowly up to Luffy's face as though just looking at him made Law tired.

"You can have mine. I'm good," Law refused.

"But it'll make you happy," Luffy protested. "Smile, and I'll give you some ice cream."

"I'm fine. I don't need ice cream."

"Just give me a big smile, Torao."

"Alright, alright," Law conceded. He ran his hands over his face, mentally preparing himself. He flashed a toothy grin at Luffy, though his eyebrows were still furrowed. It was the kind of look that appeared naturally only when he was taunting his opponents. Some might even say the expression itself was threatening- a look that suggested some kind of sadistic pleasure behind it.

"No, not like that," Luffy pouted. "That's a murder smile. I want to see Torao's happy smile."

Luffy set the bowls of ice cream down and climbed into Law's lap. He didn't understand why Law couldn't smile well, but maybe he just needed a little help.

"Smile!" Luffy encouraged him, taking hold of Law's cheeks with his fingers, pulling his mouth up into a sufficient closed-mouth smile. He kind of looked happy though his grumpy eyebrows still said otherwise. Luffy couldn't help but laugh at the juxtaposition of the two halves of Law's face.

"What are you doing, Mugiwara-ya!?" Law grabbed Luffy's hands, ripping them away from his face. He massaged his pinched cheeks with his own hands.

"I was just trying to help you smile," Luffy said with a pout. "I only want to see that you're happy, but you never smile."

If his stupid Torao didn't want to smile and be happy then Luffy couldn't make him. He was just going to have to stay grumpy forever. Luffy decided that he was done thinking about it. He dumped all the ice cream together into one bowl. He scooped up as much as he could get onto a spoon. He sloppily shoveled spoonfuls of it into his mouth as he tried to think of things other than getting get Law to smile.

The sound Luffy heard next startled him out of his thoughts. He wasn't expecting it, and at first he wasn't sure just what he'd heard, but it sounded like Law laughing. He turned to look at Law to see that he had what appeared to be a real smile on his face. The curve of his mouth was suddenly so soft, so genuinely happy. Luffy blinked at him, wide-eyed and confused.

"How did you get ice cream on your nose?" Law laughed, leaning in to wipe the tip of Luffy's nose with his finger. "I don't want to encourage you, but you really are too cute sometimes. Especially with that little pout," he admitted.
