THIS IS RE-UPLOADED FROM MY MAIN ACCOUNT. :

Ugh. I know what you're thinking. OCfic automatically equals shit. Well, you might be right, but I put my time into this, and tried to make it as well-written as possible, and tried to make something original out of it. The O still stands for original, right? I've had this idea on my mind for a while, and I just wanted to write it down. It's more like I created the characters around the idea, and not the other way around. So far, I've had a lot of fun writing it, and I really hope you get just as much enjoyment out of it as I did. :)

I hate to make such an innocent fic rated T. ;_; There's going to be some foul language, however, and I didn't want to offend anyone.

On the subject of the pairings: I'm not going to tell you them, you'll just have to continue reading to find out what they are. They're widely supported, however. And they're het. Tust me, I like yaoi just as much, but again, I'm just writing down what's been floating in my mind. I'm also the kind of person that reads fics for pairings I don't support because I like reading good fanfiction. I realize everyone isn't like that, however. DON'T LIKE IT? DON'T READ IT.

So, without further adieu, I present Liar, Liar. Happy reading! -Rain

Chapter 1

"Will you please brush your hair?" Mattia begged, holding out his friend's hair brush.

"Make me," she giggled in response.

"But you know we're going to have guests over tonight"

The girl stood in the doorway of the attic, pondering what her friend just said. "Nah," she ran out the door and down the stairs. Mattia sighed. Even if Rosario's hair was brushed, it wouldn't have made a difference. Her wild blonde hair reflected her personality to a T. Seeing it straight was an oddity to everyone. He set down the brush with a sigh, and calmly walked down the stairs.

"The day's not getting any younger, Mattie!" Rosario called as she dashed away once more. Mattia had no choice but to run after her to catch up. They ran down each of the floors of the Vongola mansion, right up until they reached the huge back door. Two men, clad in sweatshirts and sweatpants, walked in through the large wooden doors.

"Good morning Mr. Yamamoto! Happy Birthday Mr. Sasagawa!" Rosario beamed, acknowledging the two guardians.

"Good morning. Happy Birthday," Mattia politely greeted the two, out of breath from running.

"Isn't it extremely early for you two to be running around like this?" Ryohei wiped the sweat off of his forehead.

"You and Mr. Yamamoto always run this early," Mattia pointed out.

"Yeah, but we're not young like you are," Yamamoto laughed.

"Well, it's a surprise what we're doing, anyway." Rosario replied. Actually, it wasn't. The two had been making the family members birthday cakes since they were young. (The children learned early on how fend for themselves in case nobody was home. Cooking was second nature now.) Of course, there would always be a professional, lavish cake at the celebrations, but the family all thought it was too cute to pass up the youngsters' tradition.

"We'll leave you alone, then," Yamamoto ruffled Rosario's hair as he and his running partner left.

"Noooo! That's too many berries," Mattia tried to stop Rosario from adding any more of the plump fruit they had gathered from the private gardens into the mixing bowl.

"It's berry icing, Mattie" she rolled her eyes, pouring in the rest of the berries, much to the younger's chagrin.

"But now you won't be able to taste the icing," he pointed out.

"It'll be fine. Now shut up, and get the cake," Rosario ordered, pointing to the cooling plate piled with fluffy vanilla goodness behind her. With an annoyed expression, Mattia stepped down from his step stool and returned with the cake.

"You two are up early," a cool and collected voice chimed in behind them. Reborn walked up to the coffee pot and poured a large amount into a mug he produced from an overhead cabinet.

"Good morning, Mr. Reborn," Mattia acknowledged his tutor.

"Carpe Diem!" yelled Rosario, too busy spreading sticky icing on the cake to care about turning around.

Reborn chuckled before taking a sip of his coffee. To the two children, he was the coolest person to ever walk the face of the earth. He not only homeschooled them in every academic subject, but also taught them self-defense and weaponry. It was through this that Rosario found her passion for hand-to-hand combat as well as learning that she was a natural master the art of the sniper rifle by the age of 10. Mattia, however, enjoyed using his mind more than his fists and enjoyed the "classroom" time that the three of them shared. Indeed, Reborn had essentially become the father that they never had. Rosario and Mattia learned early on that they were adopted by the Vongola, and had never met their birth families. They were told that they were given up by their parents, citizens under the family's rule, who trusted the boss they were indebted to for his protection.

And they never questioned this.

"We're just making the use of our free day," Mattia gave a toothy grin.

"Then I'll enjoy my day of not teaching," Reborn replied, beginning to leave the kitchen. "Oh, and please brush you hair before anyone comes over," he looked at the blond girl "Rosie."

The dreaded word. The one name you didn't dare to call Rosario. Reborn knew this and he loved to annoy her with it.

Rosario's head slowly turned to face the professional hitman, a stony glare etched on her face. "You know I hate it when you call me that," she mumbled. She quickly turned her attention to the cake, and whispered something inaudibly that sounded like "Stupid girly name…"

As soon as the children had enough of the adults' boring conversations, they enjoyed another birthday tradition of theirs by having a little fun of their own in the attic-turned-bedroom. The two always watched movies and played board games that they snuck up from other parts of the mansion. By now, however, they had stopped paying attention to the movie, and were locked in a fierce game of Candy Land. Rosario drew the last card in the pile.

"Darn it! Why don't you ever draw the stupid gumdrop card?" She reluctantly placed her piece at the beginning of the rainbow trail.

"And you were soooo close," Mattia mocked, collecting the cards to reshuffle them.

"This has got to be a world record for the longest game of Candy Land ever played," Rosario crossed her arms and glared at the board.

Mattia didn't reply. He was deep in thought with a question that had been bugging him for a while.

Rosario glanced up at her friend when he didn't respond. "What's up?"

"I was just thinking again," Mattia replied solemnly, not taking his eyes off of the cards.

"How many times do we have to go over this?" Rosario sternly glanced at him "We have nothing to do with the inner workings of this family." This was always on Mattia's mind, and he'd been bringing it up more and more frequently.

"I just have this weird feeling that we might have something to do with that missing mist guardian."

Rosario paused, and raised an eyebrow. "You over think everything. What would the tenth mist guardian have to do with us?"

"You never know…" The story played out in Mattia's head. He's heard it many times, and had come to memorize it. Although, there wasn't much to it.

The mysterious mist guardian, obsessed with his own goals, betrayed the Vongola Decimo. Upset, the boss kicked his own guardian out of the family. Nobody knows of his current whereabouts, or even if he's still alive.

"What did he do that was so bad?" Mattia would ask. Reborn ruffled the boy's hair.

"I can't tell you now. When you're older."

"Look," Rosario caught Mattia's eyes this time "If there's something that they need to tell us, they would have said something by now."

"What if they're lying?"

"Tch. Would Boss lie to us? Would Reborn lie to us?"

Mattia pondered that last statement. He wanted to retaliate, but the words got stuck in his throat. True, he trusted Reborn, but at the same time, he just wanted to get some answers.

"Whatever. Let's pack this game up. I don't want the gumdrop card again." Rosario huffed, folding up the brightly colored board and placing it in its box.

And that was the end of that conversation.

And that'll be the last time I write an AN at the top. They'll all be at the bottom from now on~

This chapter was a bit iffy in my mind. I think they get better, but it's my own work, so I don't know if you can trust my opinion. xD

DO NOT expect this to update often. I only write my OC fics in times of extreme boredom in my study hall.
