A/n: Chaos! This is a fic dedicated to Giotto for his Birthday (although it's late), and it's a collaboration by me and Reinariadne. It's G27, with a slight bit of 1827 and it will be split into two chapters. Basically, this will be a two shot. So, before we continue, I would like to stress that this fic is GiottoXTsuna and slight HibariXTsuna, so if you have any problems regarding this (the pairings or Yaoi), I suggest you don't read this because it will be bad for your heart and we want our readers to live long. :D

Back to the matter at hand, Giotto is 21 years old, Tsuna is 17 years old and Hibari is 18 years old. This fic is rated T and will include time travel! With that done, onwards to the story!

Apology: We humbly apologize for being late for your birthday, but it wasn't our fault your birthday fell on our examination day. :) Happy Birthday, Giotto!

Summary: A birthday wish was made, to cast his doubts away. A promise was then made, and perhaps it was fate. G27, slight 1827.

Giotto stared at the round mold of chocolate cake feeling indescribably empty. He was enclosed in the four walls of his office, with his paperwork strewn all over the floor and the flame of the lone single candle flickering slightly.

That day was the birthday of the boss of the prestigious Vongola, Vongola Primo.

As unfortunate as it as, an unexpected fight had broken out earlier that day between two groups under the control of the Vongola, and Giotto was needed to settle the animosity between the two.

On his birthday.

He wouldn't have minded though, he thought rather bitterly as he watched the melted wax drip onto his chocolate cake.

His guardians had stated that Giotto deserved a break especially on his birthday and they had all volunteered to settle the matter for Giotto instead.

And hence on this very day, the Vongola Primo was left alone with no one to celebrate his day with.

Giotto sighed. "I might as well get this over with, and then I'll get back to my paperwork," he muttered softly to then closed his eyes and whispered a wish, blowing out the flickering flame with a single breath. I wish... that i could find out how the Vongola is like in the future.

Eyelids fluttered open to reveal honey golden eyes after a second or two of silence. Although I know that that will never happen, I can't help but wish that I was able to find out what it's like now.

He smiled wryly as he reached out to remove the slightly melted candle from cake. And he stopped.

The jewel on his ring glowed a soft blue, emitting soft pulses of heat throughout Giotto's arm. Giotto inhaled sharply in apprehension. What's going on?

The next thing Giotto frenzied mind knew, he was drowning in a sea of black.

Giotto blinked, lifting an arm to cover his eyes from the blinding sunlight. "Eh…? Wasn't it night time?"

He sat up slowly, looking around and shaking his head to clear the dizziness. To his left and right, he saw trees and bushes, a few benches, and he was lying on a patch of soft grass. A park, he concluded. He was in a park. Or rather, his office had turned into a park.

"Where the hell am I?"

A petite hand stretched out towards him caught Giotto's attention. His gaze trailed up to meet curious hazel brown eyes.

"A-Are you okay?" The young boy, probably about 14 years old, nervously choked out.

Giotto blinked at the adorable young boy in front of him before accepting the outstretched hand. He dusted off imaginary dirt off his clothes and gazed at the boy from earlier. The boy was literally a head or two shorter than him.

He caught the boy staring curiously at him.

"A-Are you a p-performer? A m-magician? T-the cape looks like I-it's make of good quality."

Giotto stared at the boy. What on earth was he taking about?

"No, I'm not a mere performer, I'm the Von—" Giotto paused. He shouldn't be giving out his title randomly to strangers, and he usually doesn't, but there was something about this young boy; his sincere, open face that made him want to spill everything.

The boy tilted his head cutely to the side in confusion. "Von?" He repeated unsurely, scrunching his nose up.

"I mean, I-I am a performer! Haha!" Giotto had the feeling that he was just digging his own grave, but he didn't really have much of a choice.

The boy's face brightened in delight at Giotto's confirmation. "I guessed right! Well, it was nice meeting you, Ojisan*! Don't sleep on the floor out here; you'll catch a cold!"

Giotto blinked before realization dawned upon him. "I'm nowhere near the age of an Ojisan, Shonen*," he joked lightly. "And I certainly wasn't asleep. It was nice meeting you, young boy and—" The cold glint of the metal caught Giotto's eye. He gaped at the all-too-familiar ring sitting at the boy's chest.

He knew it. He knew that ring all too well. That shade of blue, that sliver glint of metal, that intricate patterns...

The Sky Vongola ring.

The brunette stared at him in confusion, before his eyes travelled down to the ring at his neck. "Oh! This…This was a present from my erm, my great-grandfather!"

Giotto took a few moments to process that information. "Shonen," Giotto spoke slowly, unable to come to terms with the truth. "Tell me, what year is it?"

"Oh, erm, it's 2013 this year. Is something wrong?" The brunette asked, his hazel eyes worried and pulled into a crease along his brow.

There was no doubt about it. The boy had just confirmed Giotto's suspicions.

It all made sense now. His wish came true. He was in the future. And if this was true, he would technically be this young boy's grandfather.

And what Giotto had a hard time grasping was that this young boy, who could barely form an audible sentence without stuttering, was actually a descendant of the Vongola.

Giotto vaguely realised that the boy was awaiting his reply and he blinked. "N- Nothing. What's your name, Shonen?" Giotto smiled charmingly, clapping a hand onto the young boy's shoulder, producing an audible squeak from the latter.

"T-Tsunayoshi. Sawada Tsunayoshi. B-But call me Tsuna," Tsuna stammered, blushing fiercely.

Giotto smiled as gently as he could. "Tsuna, be mine for today."

Tsuna pouted as he handed Giotto his spare clothes. "You didn't have to phrase it that way," he muttered with a dark blush. "It was really misleading!"

Giotto's fingers brushed against Tsuna's as he received the clothes. He laughed. "Really? I just wanted to somehow pass time since I have no plans for today. I like you so I wanted to get to know you better."

Tsuna flushed a deeper red as he threw the orange towel at Giotto's face. "That! Stop saying stuffs like that!" As he watched Giotto laugh heartily at him with a pout, he didn't know why and he couldn't pinpoint the exact feeling either, but he felt a deep, unexplainable connection with the Ojisan somehow. That their meeting in the park wasn't just a coincidence.

Tsuna actually felt at ease with this Ojisan. Well, he trusted his intuition.

"The toilet is to your right. Go ahead and change. I'll cook lunch."

And as Tsuna entered the kitchen and placed the frying pan on the stove, he inhaled and exhaled deeply, curling his fingers around the ring dangling at his neck. A bubbling excitement stirred in his stomach, his intuition swarming around in his guts. "What's this? I can feel it. Today is going to be a day like no other. Something will happen. Something good?"

Tsuna absentmindedly grabbed some eggs from the fridge and cracked it open into the frying pan.

And with the frying spoon, Tsuna worked his magic.

"Tsuna? What's that you're making? It smells wonderful."

Tsuna turned to see Giotto sniffing the air, dressed in his spare clothes. It was awfully (sexily) tight fitting on him.

"I'm making us some omelets; you can take a seat first."

Giotto only stared at Tsuna's lithe back as he settled himself at the dining table, watching Tsuna work his way in the kitchen. He looked on with interest as the yellowish flat something was scooped onto a plate, and placed before him.

The weird food that Tsuna had made for him had wisps of smoke emitting into the air and the tempting aroma of what Giotto believed was eggs wafted into his nose.

He tasted the concoction, mindful of the expectant and curious gaze of his descendant.

And he didn't think he would be doing the food justice if he tried to describe it. The rich flavour of the egg was prominent on his tongue and complimented by whatever seasonings Tsuna had used.

"You've gotta teach me this," he mumbled through his mouthful of food.

Tsuna blinked. "What? It's just an omelet though." He watched on with interest as Giotto gobbled down his food, amazed at the sheer speed his omelet disappeared into Giotto's stomach.

And the next thing he knew, Giotto was staring expectantly at him.

Tsuna blinked before handing the frying spoon over to him. "It's simple. Just fry it, the egg."

"..."

"Awww, come on Tsuna! Don't be mad!"

Tsuna stubbornly refused to acknowledge the whining Giotto, and kept his eyes straight ahead as he walked through the rather crowded streets.

Giotto's eyebrows scrunched together into a frown. He didn't like it when Tsuna, espesially Tsuna, was ignoring him.

"Tsuna!" He grabbed Tsuna's wrist as gently as he could, causing Tsuna to squeak in surprise and turn to Giotto.

"I-I'm sorry!" Giotto blurted out without giving Tsuna a chance to even open his mouth to protest. "I really didn't mean to! I didn't even know how it happened! I swear!"

"...But you broke it!" Tsuna pouted with his cheeks flushing red. "You broke my frying pan!"

Giotto ignored the tingles pleasantly running up his fingers and arm at the skin to skin contact with Tsuna. He pouted along with Tsuna. "Please forgive me?"

Tsuna blushed a deep red as he yanked his arm out of Giotto's grip nervously. "Y-you're forgiven! Geez, why do I even bother...?" He trailed off softly, looking at the ground with red tints on his cheeks and ears.

And Giotto thought that it was the most adorable thing he had ever seen. He slipped his hand into Tsuna's before interlocking them. "Because you like me, that's why!" He stated cheerfully.

"I—"

Giotto only smiled and silenced Tsuna with a finger. "So," he continued cheerfully, as if he had not just said something really embarrassing, "Let's go search for a new frying pan!"

And together, they walked down the street, hand in hand, completely oblivious to the numerous stares they had attracted during their small commotion.

Until Tsuna almost tumbled backwards by the harsh tug from Giotto.

"Gio— Oh, Hibari san!" Tsuna exclaimed brightly, tilting his head up to look at his cloud guardian.

"You almost knocked him down, Tsuna," Giotto joked lightly. However, he had his gaze pinned on the intruder, as with Hibari. "Or more like he knocked you down."

Tsuna frowned in concern at the hardened expression on Giotto's face. "Giotto?"

Hibari stared at Giotto with no apparent expression on his face, analyzing him silently. "Watch what you say, herbivore."

"I'm not that poor to not be able to afford meat, Hi-ba-ri san."

Tsuna felt his hair standing at the rising tension between the two. "W-what are you d-doing here, Hibari san? W-what a coincidence! Haha…"

Hibari blinked and turned his attention onto Tsuna. "Protecting the peace of Namimori so that old grandpas," his eyes shifted to Giotto, "won't prey on innocent youths," his eyes travelled back to Tsuna. "Under my watch."

Giotto narrowed his eyes and sent a warning glance to Hibari, who promptly ignored it.

"Be careful of strangers you just met, herbivore."

"Eh?" Tsuna could only wonder what was going on as Hibari leaned in closer to him. He felt Giotto's grip tighten on him.

"Because if you ever dare to go against me," Hibari breathed onto Tsuna's neck. "I'll bite you to death."

And promptly bit on the soft flesh.

Tsuna had not even been given the time to react before he was roughly tugged away by Giotto. The grip on his wrist was uncomfortably tight and stiff.

Giotto's eyes flashed golden. "What kind of 'protector' are you if you go around sexually harassing others?!"

Hibari merely straightened himself with a smirk tugging his lips. "Good day, herbivore," he directed at a blushing Tsuna before turning heel, his black coat fluttering in the wind behind him.

That's all for chapter one! I hope we did good enough to please you all, and of course Giotto san too! Review will be greatly appreciated!
