A/N: I wasn't actually planning to place this until much later but since you guys really want to know what happened to the other Tsuna… I have no choice! This is more like a teaser chapter though, because after this… we'll be focusing more on the naïve little Tsuna. I hope you guys enjoy! Read and Review!

Oh yeah, one more thing… Do you guys think I should make a series of 8027 fluff stories based on the pictures of the scrap book Yamamoto gave Tsuna on his birthday? Your thoughts please!

Parallel to Your Heart

By ilYamaTsuna7227li

Chapter 2

The last thing I remember was being held in your arms as my eyes slowly closed into slumber.

Meanwhile… In a certain parallel world, under a certain cherry blossom tree…

Blink.

Warm caramel eyes fluttered open as he stared up.

Blink.

A single petal of a sakura landed on his forehead as his eyes scanned the area through his limited peripheral vision.

Eh? Where am I? The park? Tsuna thought as he looked at the sakuras dancing in the breeze. His eyebrows furrowed in confusion. But the last thing I remember was watching movies with Ya- I mean Takeshi… So how come I'm at the park?

"Tsuna-kun…?" Came a familiar voice. Tsuna's eyes snapped towards the voice and to his shock, he saw Sasagawa Kyoko peering down at him in worry. He was so shocked he failed to register the close intimate way she called him and the fact that her hair was shorter than he last remembered.

"Sasagawa-chan!" Tsuna said gasping. It took a few seconds for Tsuna to realize that he was actually lying on his (1)love rival's lap.

"HIIIIII!" Tsuna said as he got up and scrambled as far away from the orange-head as possible. However his movements were too fast and before long, he found himself falling back. However, thankfully someone managed to steady him on time before he fell down and hit his head.

"Whoah, steady there Tsuna." Came a familiar voice. Tsuna's eyes widened as he turned around immediately. He felt the familiar feeling of his heart thudding against his ribs

"Ya-Yamamoto!" Tsuna said as he threw his arms around the stunned baseball player, and totally forgetting that he was right in front of Kyoko. It also seems like he forgot the fact that he and Yamamoto just swore to each other that they would be calling each other by the first names… However, it seems like forgetting this was a good thing.

"E-Eh? T-Tsuna?" Yamamoto stuttered as he stumbled a bit because of the brunet's sudden action. If you looked closer you would see a small blush dusting his face. Tsuna leaned back and gave Yamamoto radiant smile. The baseball idol's blush became a tad bit darker.

Tsuna-kun? Kyoko thought in confusion as she stared at the back of the smiling brunet. Did Tsuna-kun just call me Sasagawa-chan?

"Jyuudaime!"

"Sawada!"

The two familiar voices made Tsuna let go of Yamamoto. He failed to notice the sigh of relief that Yamamoto let out when he did this.

"Gokudera-kun! Senpai!" Tsuna said as he smiled at the two. The 2 guardians slowed to a stop as they neared Tsuna.

"Senpai? When did you EXTREMELY stop calling me 'onii-san', Sawada?" Ryohei asked as he looked at the brunet. The Vongola stared at him in confusion.

"O-Onii-san?" Tsuna repeated.

"Jyuudaime, are you okay?" Gokudera asked as he kneeled down to look at his boss.

Tsuna looked at his self-proclaimed right-hand man and nodded. "Yeah, I'm fine… why? Is there a reason for me not to be?"

"Well jyuudaime, seeing as you were hit by the stupid cow's bazooka… I thought…" Gokudera began as he glared at Lambo who was crying after being hit by Gokudera.

"Eh? Lambo?" Tsuna said as he saw what Gokudera was looking at. "When did you get back from Italy?"

There was silence.

"Eh? Italy?" Lambo said as he rubbed his nose trying to wipe away his snot and tears. "Dame-Tsuna must've hit his stupid head too hard. Lambo-san will never leave mama!"

"Lambo! It not nice to call Tsuna-san's head stupid!" I-pin said in disapproval. (Note: I made it wrong grammar on purpose)

"I-pin's here too…" Tsuna mumbled his eyes widening slightly. What did this mean? Why were Lambo and I-pin here? Weren't they supposed to be in Italy at the Bovino mansion? And why was he in the park when he vaguely remembered falling asleep in Yamamoto's arms in the living room? And also why is Sasagawa-chan looking at him (2)like that? Why is her hair shorter? Why did she call him 'Tsuna-kun'? And why… did Yamamoto act as though he had never hugged him before?

"Is there something wrong Tsuna?" Yamamoto asked when he saw the boss going pale.

"I-It's nothing…" Tsuna said shaking his head lightly as his eyes hid beneath his bangs. "So uhm, where's Fuuta? And Reborn?"

Yamamoto looked at Tsuna weirdly. "Fuuta's at home with your mom. He's helping her with the chores."

"M-Mom?" Tsuna repeated his voice shaking. His mother was home? And with Fuuta too? Fuuta who was supposed to be in Spain? And his Mom who's suppose to be on a world tour with Iemitsu?

Tsuna's form shook a bit as he leaned against the sakura tree feeling a bit tired and nauseous.

"Tsuna?"

"Jyuudaime!"

"Tsuna-kun/Sawada!"

Almost immediately he felt these 4 people surrounding him. He looked at their worried faces, his eyes lingering longer on Yamamoto's amber orbs. He gulped thickly, almost afraid to ask the next question that popped in his mind. The question he knew would either send his heart racing or plummeting to the deepest parts of the ocean.

"U-Uhm, Yamamoto…" Tsuna began slowly as Yamamoto tilted his head slightly once he addressed him. The boss felt uncomfortable at the fact that 3 other people were staring at them as though they were watching a ping-pong match.

"Hm? What is it Tsuna?" Yamamoto said with a smile. Tsuna felt his heart's tension ebbing away at the expression.

"I-I k-know this might be a weird t-thing to a-ask b-but…" Tsuna said as he inhaled deeply. He looked at Yamamoto's face searchingly before he said in a serious tone. "What am I to you?"

There was silence. Tsuna could practically hear all their heads buzzing in confusion at the question.

"That is a weird question." Yamamoto said finally as he smiled at Tsuna. The brunet sighed in relief. Everything was okay… Yamamoto was going to tell him that he was the most important person to him, and probably add some cheesy line that would send his heart pounding.

"Tsuna is…" Yamamoto began as he thought but then he suddenly grinned at the young boss. "My bestest friend!"

Eh?

Tsuna looked at the baseball idol his eyes widening at what the other said.

Friend?

"Hm? Tsuna?" Yamamoto suddenly said, immediately everyone's attention snapped to the brunet. The brunet's eyes hid behind his bangs as he leaned back against the tree.

"Damn, this is not good." Were his last words before he closed his eyes and fainted.

"Wake up. Wake up Dame-Tsuna!" Came a familiar voice. Tsuna's eyes snapped open just as Reborn was about to hit him with the familiar ten-ton Leon hammer.

"R-Reborn!" Tsuna said as he sat up abruptly to avoid the other's hammer. Leon transformed back into a chameleon as Reborn looked at his student curiously.

"Oi Dame-Tsuna are you alright?" Reborn said as he raised an eyebrow towards the other. The young boss gave off an awkward laugh.

"O-Of course I'm alright Reborn! What makes you say that I'm not?" Tsuna said as he looked around his room. It still looked the same except…

"Neh Reborn, where's the scrap book I usually keep here?" Tsuna asked as he pointed at a certain shelf. Instead of a scrap book, in its place was a journal.

"Scrap book? What scrap book?" Reborn asked as his eyes followed what Tsuna was pointing at.

"You know, the one given to me by Ya-" But Tsuna didn't finish his sentence as the memory of what happened to him before he fainted flooded in his mind. His eyes widened as he put down his hand.

"Dame-Tsuna?" There was silence as Tsuna's eyes shadowed.

"Neh Reborn," Tsuna began in a monotone voice. "Where's mama?"

There was a pause.

"She's in the kitchen making dinner for you and the kids." Reborn said with a raised eyebrow. "Why?"

"Reborn, is Bianchi still here?"

"Are you asking if she still lives here? Of course she does." Reborn said getting suspicious at Tsuna's questions.

"And Fuuta?"

"Fuuta is in the other room playing with Lambo and I-pin." Reborn said as he tried to read his student's expression.

"Reborn, who is the person I like?"

Reborn crossed his arms. "Isn't it obvious? You've been chasing her ever since middle-school began."

"Just answer me."

"It's Sasagawa Kyoko." Reborn said.

"Have I always called senpai- I mean, Sasagawa Ryohei 'onii-san'?"

"Yes, ever since you realized that he's the brother of your crush." Reborn confirmed.

"What happened before I woke up lying on Kyoko-chan's lap?" Tsuna asked his voice a bit cold.

"You were hit by the stupid cow's bazooka." Reborn said. There was silence. "What's with all the questions, Dame-Tsuna? Did the stupid cow's bazooka cause you amnesia or something?"

Tsuna didn't answer as he lied back down on his bed. He placed an arm over his eyes, trying to hide the conflicting brown orbs from his tutor.

"And Yamamoto?" Tsuna suddenly asked, surprising the sun arcobaleno.

"What about Yamamoto?"

"Does he-" Tsuna hesitated as he bit his lip. "Does he… Does he have someone he likes? Or is he currently in a relationship with someone?"

Reborn absorbed this strange question as he answered. "No. Why?"

Tsuna turned to his side as he let out a sigh of relief. He didn't know if his heart could take the fact that his Yamamoto was going out with someone. Although, he really shouldn't be worrying about that right now. What he should be worrying about is the fact that everything around him seems to be not what he last remembered it to be.

However he had already formulated possibilities on what could've happened, seeing as he was hit by Lambo's bazooka of all things.

Possibilities:

*Lambo's bazooka hit him in the head and altered his memories

*He was transported to a parallel world after this world's Tsuna got hit by the bazooka. In other words they switched places

*This was all a bad dream he was gonna wake up from soon.

Seeing as it was impossible for Lambo's bazooka to alter memories, and seeing as he still hasn't waken up from this dream (which could only mean this was really happening)… It only leaves one possibility:

I must be in different world then… Tsuna thought to himself as he grasped his front shirt. In a world where Yamamoto and I aren't…

"Speaking of Yamamoto…" Reborn suddenly said, snapping the brunet out of his thoughts. "Your rain guardian is downstairs right now with Gokudera."

"Eh? Yamamoto's here?" Tsuna said as he sat up eagerly. Reborn gave the other's enthusiasm a suspicious glance.

"Yes, he and Gokudera are worried since you've fainted twice already." Reborn said as he walked to the door and opened it. "You should go down and tell them you're okay."

"Yeah." Tsuna said as he clambered out of his bed. He made his way to the door eager to see the face of the baseball idol.

Meanwhile… Reborn looked at Tsuna's face with suspicion. Something was wrong with his student… Something became different about him when he was hit with the bazooka… And he was going to find out, what.

"This is your entire fault baseball idiot." Gokudera grumbled for the umpteenth time. "You made jyuudaime faint."

Yamamoto frowned at the bomber's accusation. He opened his mouth to retort what the other said, however the sound of someone going down the stairs threw him off. He stood up abruptly making his way out of the living room to check who it was.

"O-Oi! I'm not done talking to you yet!" Came Gokudera's disapproving voice.

Yamamoto walked towards the stairs as he looked up. He saw Tsuna eagerly going down the flight of stairs.

"Tsuna!" Yamamoto said, letting relief seep into his voice. At the sound of his name, Tsuna locked eyes with the baseball idol. The brunet gave Yamamoto a smile.

"Yamamoto-!" Tsuna said as he stopped in front of the baseball idol. He was about to throw his arms around the other but then suddenly he remembered that he was suppose to like Kyoko in this world and with a heavy heart, he held himself back.

"Tsuna, I'm so glad you're alright." Yamamoto said as he grinned at the other. Tsuna looked at the swordsman longingly before he looked down.

"Sorry for worrying you." Tsuna said as he sighed in disappointment. The rain guardian did not miss the sigh as he looked at the boss curiously.

"Tsuna?"

"Jyuudaime!" Came Gokudera's voice as the bomber appeared behind Yamamoto. "Jyuudaime, are you feeling okay now?"

"Gokudera-kun." Tsuna said smiling at the Italian. "Yeah I'm feeling much better now."

Gokudera sighed in relief. "That's good to hear."

Tsuna looked at the wall clock and saw that it was late. "You guys should stay for dinner."

"Thanks for the offer Tsuna but Dad's waiting for me to get home." Yamamoto said with a sheepish grin.

"Oh." Tsuna said trying to hide his disappointment. "Okay."

"I don't mind staying for dinner jyuudaime! Your mother's cooking is the best!" Gokudera said with enthusiasm.

"Mom would be happy to hear you say that." Tsuna said smiling at Gokudera.

"Well, I'll get going then. See you tomorrow at school, Tsuna, Gokudera!" Yamamoto said with a wave. He turned around heading to the door. Tsuna watched this action with wide eyes as he absently reached out a hand and grabbed Yamamoto by the arm.

The baseball idol stopped when he felt someone hold him back. He looked back his eyes wide. "Tsuna?"

"Jyuudaime?" Gokudera joined in on the confusion. Tsuna blinked once and he blushed when he realized what he did.

"A-Ah, g-gomen!" Tsuna said as he looked away, his eyes shadowing. Gokudera and Yamamoto exchanged looks at the brunet's strange action. There was silence.

"Y-You should get going now baseball idiot." Gokudera said breaking the silence. "Didn't you say your dad was waiting for you?"

Yamamoto looked up startled at the bomber before he shifted his gaze worriedly at Tsuna. "A-Ah… I'll s-see you guys…" And with that, Yamamoto walked off but this time Tsuna didn't stop him. He was looking at the opposite direction, a thinking look on his face.

"Let's go to the kitchen jyuudaime." Gokudera said as he placed a hand on the distracted brunet's shoulder.

"A-Ah." Tsuna said with a nod before he allowed the storm guardian to lead him to the delicious scent of his mother's cooking.

Yamamoto, why aren't you mine?

FEW HOURS LATER

Tsuna sat alone in his bed, staring at the window. No pictures of him and Yamamoto were in the room. There were only some random games and some test papers in most of his closet. The only interesting thing he found was the journal on the side cabinet where his scrap book was supposed to be.

Tsuna flipped open the page and sighed. Written in capital letters on the first entry was the name of this world's Tsuna's crush: SASAGAWA KYOKO

Tsuna reached out tentative fingers and stroke the writing. It was true that from what he knows, Sasagawa Kyoko was sweet and kind, and every boy's dream. He even remembered a time in his world when he was talking to Sasagawa-chan and Mochida saw them. The kendo sempai challenged him for Kyoko's love although the person Tsuna really liked was Yamamoto. However, since Yamamoto was watching the match, the brunet couldn't afford looking bad so yeah… he defeated Mochida, with the help of the dying will bullet.

So Mochida's obsession is a good example of Sasagawa-chan's popularity. Which makes it not shocking that the Tsuna of this world likes the younger Sasagawa.

The brunet let out a sigh as he flipped through the next page. He couldn't help but laugh when he saw that what his other self wrote in the next page were mostly the tortures he received under Reborn's training.

Tsuna plopped down onto his bed as he continued to read. He flipped the pages impatiently when he saw that Yamamoto's name was not in any of them. But then he stopped in shock at one journal entry which was dedicated solely to a certain rain guardian.

Yamamoto is a very nice guy. He's always cheerful and he's always calming us down. I'm really thankful that he's in the…'family'. Out of everyone he is probably the most normal one. But you know, today I saw Yamamoto playing baseball with a bunch of kids from the future. He looked… so happy. And at that moment I couldn't help but think that maybe Yamamoto would've been better off not meeting me…

Tsuna traced the sad words with his fingers. The Tsuna of this world seems to be suffering a lot. He looked at the date and saw that what was written was the word 'future' instead of a specific date. Ah, so this was the time when they fought in the future.

The young boss continued to flip through the pages and he stopped at a certain entry which seemed to be dedicated to Yamamoto again.

Today, onii-san and Gokudera-kun got into an argument again but thankfully Yamamoto was able to calm them down before they caused destruction. It's really nice to have someone like Yamamoto to depend on. But you know, I noticed that Yamamoto seems to be more distracted than before. When I talk to him, he responds but his heart doesn't seem to be there. I can't help but get worried. I know that Yamamoto blames himself for our loss in the future, but he shouldn't! It's my fault not his! Why can't he see that?

Tsuna's eyes widened at the words. It seemed like the Tsuna of this world cared greatly for Yamamoto and yet…

"He doesn't know it?" Tsuna murmured as he flipped unto the next page.

Yamamoto lost the rain guardian trial although he defeated the first rain guardian. Asari Ugetsu said that I should know why he lost but my mind is blank on why Yamamoto lost. True, I felt uncomfortable on the way he fought that night. I kept wondering why he had such an expression on his face. I didn't like that expression on his face. It wasn't the usual smiling and calming face that keeps my friends and I together, it was a face filled with regret… It didn't suit Yamamoto at all.

Tsuna sighed as he read over the entry. This Tsuna clearly cared about Yamamoto a lot, but he translates it into nothing more but friendship. Really? Can his other self get more naïve?

He closed the journal with a soft 'thud' before throwing it to the corner of the room. He didn't feel like reading anymore of the other Tsuna's thoughts. Instead, the young Vongola curled up in his bed taking a look at his phone. It was during moments like these he wished Yamamoto would call him. But of course seeing that he wasn't in his world, it was impossible.

His grip on his cell phone slackened as he reached for something in his pocket. It was a (3)charm Yamamoto gave him. The brunet looked at the charm, taking in the way its sides were dented and how the kanji of 'protection' was faded due to the fact that he had held it a lot of times in a death-vice grip.

The sky guardian closed his eyes as he held the charm close to his heart.

"Yamamoto…" He murmured as he curled up even more. He listened to the soft beating of his own heart and pretty soon he was lulled to sleep.

The door slowly creaked open as a certain arcobaleno entered the brunet's room. Reborn looked at his student up and down trying to figure out what seemed out of place with this Tsuna.

The hit man gave a suspicious look at the journal which was thrown at the corner of the room and he looked at the phone inches away from his student.

Was he expecting someone to call him? Reborn thought as he approached the brunet. Tsuna was breathing softly and his eyes fluttered now and again as he slept.

"Stupid student of mine…" Reborn sighed as he looked at the curled up form of the young boss. He jumped unto the bed, pulling Tsuna's legs down so that he wouldn't be curled up anymore. Tsuna didn't protest the action and instead he continued to sleep.

When the other was in a passable state of sleeping, Reborn noticed the object Tsuna was clutching to his heart.

"Hm? That's the charm Kyoko gave him isn't it?" Reborn said with a thoughtful look. He sighed as he looked at the face of his student. "I'll give you another chance to confess your feelings Dame- Tsuna. You should be thankful that your tutor has a kind heart."

Tsuna muttered something but Reborn couldn't decipher it. The arcobaleno shrugged before he hopped down of Tsuna's bed and walked towards the door.

"Have a good rest Dame-Tsuna. You might need it for tomorrow." Reborn said as he closed the door behind him. He failed to hear Tsuna utter one name as he slept.

"Yamamoto…"

Maybe if he heard it, he would've thought twice on who Tsuna liked.

(1) Love rival- you will find out why Kyoko is called that in the upcoming chapters

(2) Like that- Okay so, as well know Kyoko is slowly falling in love with Tsuna in the anime. So when Tsuna said she was looking at him like that… Well he meant she was looking at him with a sort of 'I-like-you-and-I'm-worried-about-you' look in her eyes.

(3) Charm – In the world where Tsuna and Yamamoto are together, Yamamoto gave Tsuna a charm of protection which eerily looks like the charm Kyoko gave the Tsuna of this world. Tsuna treasures this charm and he managed to keep it on him, when he and the other Tsuna traded places.

The upcoming chapters will focus solely on the other clueless Tsuna for a while. When I find an opening I will place what is happening to the Tsuna who is in love with Yamamoto in the other world.
