Parallel to Your Heart

By ilYamaTsunali

Chapter 4

"Reborn, I can't take it anymore!" Tsuna said as he plopped next to the fire extinguisher at the school halls. It was one of the yellow-pacifier baby's secret hide-outs, one that Tsuna knew well. "Please send me back home already!"

"What are you talking about now, Dame-Tsuna?" Reborn said as he appeared through a secret hatchet. He was frowning as he walked towards the blushing brunet by the floor. "What's wrong with you?" The Spartan tutor asked when he saw him.

Tsuna's blush darkened as he buried his face on his hands. "I don't know." Tsuna said frustrated. "I was talking to Yamamoto, asking him why he liked you know… me and then he said some stuff and I started feeling weird and I-! Urgh! What do I do Reborn?" Tsuna asked tearfully as he looked up.

Reborn raised an eyebrow. "Feeling weird?"

Tsuna gulped. "Y-Yeah… my stomach felt like it was full of butterflies or something and I felt nervous and…"

"And…" Reborn continued, a smirk slowly forming on his face. "…and you're heart was beating pretty fast wasn't it?"

"I…- what?" Tsuna said snapping his gaze at Reborn. The baby was staring at him amused.

"Oh no! No! No! No! NO!" Tsuna said shaking his head in denial. "It's not what you think it is Reborn! It's a completely different feeling!"

"I didn't say anything."

"But you were thinking it!" Tsuna said appalled. "Yamamoto's my best friend! He can't-! I can't-! I like Kyoko-chan!"

"Sure you do…" Reborn taunted. Tsuna got angry and stood up.

"I do! And no matter what anyone says, it won't change anything!" And with that said, Tsuna stormed off. Reborn watched the teen with exasperation and amusement.

"He'll figure it out soon enough." Reborn said as he walked towards his hatchet. "And I wonder what he will do when he finally realizes his feelings?" With that said, Reborn entered his secret quarters as it closed behind him.

"Hey Tsuna, you okay? You look angry…" Yamamoto asked as he caught up with the brunet when he entered the classroom.

"I'm fine, Yamamoto." Tsuna said as he frowned in anger. He thought back to his and Reborn's conversation and got even angrier.

I mean who does Reborn think he is? What gives him the right to tell me who I like? Kyoko-chan's sweet, kind, and she's brave in her own way! Who wouldn't like her? And plus she's a girl! So she's obviously the one I like! Tsuna insisted in his mind.

Suddenly someone poked Tsuna on the cheek. The young boss looked up, stunned.

Yamamoto was smiling at him apologetically as he said. "You know your cheeks puff up when you're angry, it's sort of cute."

On the background, Tsuna could hear someone squealing but he was too busy blushing to actually notice it.

"W-what?" He asked as he placed a hand automatically on his face. Yamamoto laughed as he placed a hand over the one Tsuna had on his face.

"Kidding. I'm just trying to get you in a good mood." Yamamoto said casually. Tsuna blushed at the contact and hurriedly retracted his hand. However, by doing so, that only left Yamamoto's hand on his cheek. The touch was warm and calming, the thought made Tsuna blush even more.

"So, what's up?" Yamamoto asked as he finally removed his hand from Tsuna's face. The brunet sighed in relief before he looked at Yamamoto.

"Nothing." He said as he looked at those amber eyes. After a few seconds he looked down. He never liked lying, especially to Yamamoto- I mean to one of his best friends.

"Doesn't seem like nothing…" Yamamoto said as he sat on top of Tsuna's desk casually, the brunet sat on his chair. "Did the kid say something to get you upset?"

Tsuna gave Yamamoto a 'how do you know me so well?' look. Yamamoto chuckled at the expression. Tsuna sighed as he finally relented.

"Yeah, Reborn said some things to me that made me…" Tsuna pursed his lips. "…angry."

Yamamoto blinked in astonishment. "That's rare. You, getting angry? What did he exactly say?"

Tsuna's eyes widened in panic. He couldn't tell Yamamoto, Reborn would massacre him. "U-Uhm… well h-he… He was really getting out of hand with all his c-comments so yeah, I got angry a-and…"

"Hm?" Yamamoto said as he tilted his head slightly, not able to understand what Tsuna was saying. Tsuna blushed at the action. "And?" The rain guardian prompted.

Tsuna's mouth was dry as he gulped. "U-Uhm, I-I…"

However, he was thankfully saved from answering when the door to their classroom opened and a sleepy teacher entered.

"Gomen for being late~" Came a familiar voice. Tsuna's eyes widened as his head snapped towards the owner of the voice. Everyone greeted the person enthusiastically, some were even saying 'welcome back'. The young Vongola boss jumped out of his seat much to the astonishment of his classmates and Yamamoto.

"Byakuran!" Tsuna said, shocked. The sleepy teacher with snow-white hair yawned as he looked at Tsuna with a smile.

"Yes, I know my name, thank you very much Tsunayoshi-kun." Byakuran said as Tsuna's classmates laughed. Tsuna blushed while beside him Yamamoto raised a skeptic eyebrow at the brunet. "And I would appreciate it if you added a 'sensei' after that name okay~?"

"S-Sensei?" Tsuna repeated the word as though it was the first time he ever heard of it.

"Yes, sensei." Byakuran said wiggling his finger impatiently. "I am after all, your social studies teacher…"

"Teacher?" Tsuna muttered to himself questioningly. There was an absolutely confused look on Tsuna's face as he thought about what Byakuran said.

Teacher?

Byakuran is a teacher?

Byakuran is my teacher?

Tsuna's expression became a horrified one as he saw Byakuran smiling at him.

"Hey Tsuna, you okay?" Yamamoto asked as he placed a hand on the brunet's shoulder.

"I-" Tsuna began as he looked at Yamamoto, trying to understand the situation. "Byakuran he's-?"

"A teacher, yeah." Yamamoto repeated with a slight nod. His expression was filled with worry as he looked at Tsuna's pale face. "He began teaching a few months ago remember? Gokudera was against the idea and you were a bit scared back then, but you figured this Byakuran was okay now…" Yamamoto explained as he continued getting blank looks from the brunet. "He went on vacation three months ago and it seems like he just got back today."

"I-I see…" Tsuna said as he looked back at Byakuran who was still looking at him with a smile.

"Okay Tsunayoshi-kun, if you and Takeshi-kun are done with your discussion then please take a-" But then Byakuran froze as his eyes widened and it became sharper. Tsuna gulped.

Byakuran recovered himself and went back to smiling. "Wait, Tsunayoshi-kun can you step outside with me for a moment? I need to talk with you."

"U-Uhm…" Tsuna turned to look at Yamamoto who nodded at him encouragingly.

"Go ahead. He won't hurt you. I won't let him." Yamamoto said with a reassuring smile. Tsuna just nodded back and he followed Byakruan out of the room.

Yamamoto watched with concerned eyes as Tsuna walked towards the door being held open by Byakuran. He met Byakuran's gaze and the ex-villain gave him a reassuring nod like he was saying, leave him to me.

The baseball idol sighed as he sat back own. The moment the door closed, students began to ask Yamamoto what was up with Tsuna's memory loss, and the baseball star could only say one thing.

"I honestly don't know."

"So… this is why the baby called me back, huh?" Byakuran said as he looked at Tsuna from head to toe. "And let me guess, Takeshi-kun doesn't know?"

"Huh?" Tsuna said confusedly as he and Byakuran talked in the empty hallway. Byakuran just smiled at Tsuna's confused face.

"Well then, hello there Tsunayoshi-kun of a different world." Byakuran said casually. Tsuna's mouth dropped open as he stared at Byakuran.

"Wait, you knew…?"

"Nope, I just realized it." Byakuran said happily. "The baby didn't tell me anything when he told me to come back and teach in Namimori. I thought for sure that maybe your relationship with Takeshi-kun wasn't going so well so he wanted me to step in and do something again…"

"Wait, what?"

"…but he actually wanted me to do something about you being in the wrong world!" Byakuran said clapping his hands, delighted. "I must admit that seems sort of fun."

"What are you talking about now?" Tsuna asked thoroughly confused. Byakuran turned to him.

"Okay, let me ask you one thing Tsunayoshi-kun, when you fought me in the future what was my greatest power?"

"Uhm, being able to channel huge amounts of flames into a pair of wings?"

"Try again."

"Uhm, oh yeah! Being able to see in other parallel worlds and transfer yourself from another parallel world to the world you're in, right?" Tsuna said shivering as he remembered Ghost.

"That's right!" Byakuran said. Suddenly understanding flooded Tsuna's mind and he almost shouted in joy. Finally someone can take him back!

"Then you can-?"

"Sadly, I lost that power when you defeated the future me." Tsuna anime-fell at that phrase. "But still, that did not stop me from recognizing that you were not a part of this world, so there must be something I can do…" Byakurna said. Suddenly, Tsuna felt hopeful again.

"So you'll help me?" Tsuna asked hopefully. Byakuran thought about it.

"Maybe." The white-haired ex-boss said. "That is, if I get my share of fun first.'' Byakuran said, a mischievous glint in his eyes. Tsuna gulped as he stepped back fearfully.

"E-eh?"

Then Byakuran chuckled. "Don't look so nervous Tsunayoshi-kun! Of course I'll help you! I owe you one for making the world so interesting! And for not killing me too." Tsuna sweat dropped.

"Uhm, you're welcome?" Tsuna said uncertainly. Byakuran nodded approvingly.

"Now go back to class and tell your classmates that I won't be coming in today, I have to talk with your mentor. Also apologize to everyone for being forgetful, and stop making Takeshi-kun worry okay?" Byakuran said with a wink before he turned around ready to leave.

"A-Ah! W-Wait B-Byakuran!" Tsuna called out. The ex-Gesso boss paused and looked around curiously.

Tsuna was looking down with a slight blush on his face. "T-Thank you." He said before he turned and ran back into the classroom. Byakuran stood there with slightly wide eyes before a serious smile lit up his features.

"He doesn't change, does he? No matter what world he's in…" Byakuran said, and as he said that, Reborn stepped out of another hatchet.

"Yeah, even the way he thanked you was similar to the way he did a few months ago." Reborn said with a smirk.

"Ah, only back then he was thanking me for bringing him and Takeshi-kun together." Byakuran said remembering fondly what happened three months ago. "I admit, playing match-maker back then was fun."

Reborn's smirk widened. "How would you like the chance to play match-maker again?"

"Oh? Are you planning something arcobaleno?"

"Yes, I'm planning to teach that stupid student of mine a lesson. He'll think of it as a souvenir when he gets back to his world."

"Oooh, I like the sound of that."

"What was that about Tsuna?" Yamamoto asked after Tsuna announced to the whole class that Byakuran was gonna be absent for today's lesson.

"Byakuran…" Then Tsuna remembered to add a certain suffix. "-sensei, just wanted to talk to me about uhm… homework that's all."

"Homework?" Yamamoto said curiously. Tsuna nodded vigorously.

"A-ah, I'm really behind on them you see." Tsuna said laughing uncertainly. Yamamoto just looked at Tsuna before he sighed and smiled.

"Okay then, if you say so." Yamamoto said. "Anyway, wanna go and eat at our place for dinner tonight? Your mom isn't home right?"

"O-Okay." Tsuna said nodding, he knew Yamamoto would find it strange and worry even more if he refused.

"Good." Yamamoto said with a smile as he reached out and took Tsuna's hand. "I'm looking forward to it."

Tsuna gripped his front shirt and bit his lip when he felt his heart beat race once more.

Gah, stupid heart.

TIME SKIP

After classes…

"Bye, we'll see you tomorrow!" Yamamoto said as he waved with his right hand, his left hand was holding Tsuna's hand and beside him, as usual, Tsuna was blushing.

"Okay Yamamoto!" A friend of Yamamoto's from the baseball team said.

"Don't go home too late you two." Another guy snickered teasingly.

Yamamoto just gave them a good-natured smile before he and Tsuna turned to leave. Beside them, Gokudera was muttering mutiny under his breath. Every now and then he would send Yamamoto a murderous glare, but Yamamoto was too busy humming happily to notice.

"U-Uhm, I'm glad you're okay now Gokudera-kun." Tsuna said trying to direct Gokudera's murderous attention away from the rain guardian. The effect was immediate. Gokudera immediately snapped his green eyes to Tsuna but this time it was accompanied with a 'loyal-right-hand-man' look.

"Yes! I'm fine now tenth! Nothing can keep me down!" Gokudera said proudly and slightly touched that Tsuna cared for him.

"That's good." Tsuna said with a relieved smile. "Don't worry about Bianchi, I'll tell her to come back to the house tomorrow so that you can-"

"No tenth!" Gokudera said, suddenly surprising Tsuna.

"Eh? No?" Tsuna said confused. "Why?"

"Hm, I'm curious too Gokudera." Yamamoto suddenly piped into the conversation. "I thought you wanted Bianchi out of your apartment as soon as possible?"

Gokudera glared at Yamamoto for a moment, as though just remembering that he was there, before looking down fidgeting.

"Well, jyuudaime as you know I have one great flaw and that is my sister. One look at her and I can go down in battle like a ragged doll." Gokudera said seriously. "I still remember the arcobaleno mist-seal trial. I could've helped you but then I went down just by seeing my sister's face once! And I don't want that to happen again!" Gokudera said his eyes burning.

Tsuna sweat dropped at Gokudera's enthusiasm while Yamamoto just laughed.

"And so jyuudaime, with aneki living one door away it becomes very convenient! With her living so close by I can finally become immune to my phobia!" Gokudera said. "And when I overcome this trial I will become an even stronger right-hand man you will be proud of!"

"I-I see…" Tsuna said "But you know you don't have to-"

"Ah we're here!" Yamamoto said suddenly. Tsuna looked up and realized they were now in front of a small apartment in Namimori.

"This is my stop jyuudaime!" Gokudera said bowing at Tsuna deeply. "Thank you for accompanying me home." And with that, Gokudera charged to the apartment with renewed vigor.

Tsuna sweat dropped when he heard Gokudera say, "Aneki I'm home!"

"Hayato welcome back." Came Bianchi's voice. Suddenly there was the familiar sound of Gokudera retching before a loud thud accompanied it.

"Oh Hayato! You're sleeping on the floor again!"

"Ahaha, they seem to be having fun." Yamamoto said with a grin.

"I'm really worried for him." Tsuna sighed. "Is it really a good idea to leave him with Bianchi?"

"He did say it was fine right?" Yamamoto said with a reassuring smile. Tsuna looked at the rain guardian's smile and felt better at once.

"Yeah you're right." The boss said, totally convinced.

"Good." Yaamamoto said, squeezing Tsuna's hand lightly. "Let's go then."

Tsuna nodded, letting Yamamoto lead the way. In the back of his mind he realized this was the first time he ever saw Gokudera's home and once again he couldn't help but wonder how come he never saw it before today.

"Hey Pops! I'm home!" Yamamoto yelled out as he and Tsuna entered the Takezushi restaurant.

"Sorry for intruding." Tsuna said, slightly bowing as he entered.

"It's no intrusion at all." Came a voice. Both teens looked up and saw the older Yamamoto walking down the stairs. "Welcome home Takeshi, and if it isn't Tsunayoshi-kun… It's been a while."

"A-ah, hey there Yamamoto-san…" Tsuna said shyly as he scratched his cheek in embarrassment. He never really thought about how Yamamoto's dad viewed their relationship.

"Now don't be shy, the two of you head up to Takeshi's room then. I'll prepare dinner." The old man said, ushering them inside. "Takeshi told me you were coming over." He said as he leaned towards Tsuna whispering. "Don't worry, I already cleaned his room so he wouldn't be an embarrassment."

"Dad!" Yamamoto said while blushing slightly. It seemed like he heard what Tsuyoshi (Yamamoto's dad) said. The old man pulled back laughing at his son's expression, Tsuna laughed with him.

"Well, get going then!" The old man said sternly before he smiled and went to the kitchen to cook them some food. Yamamoto sighed as he shook his head before he took Tsuna's hand in his and led him to his room.

…

"Well, dad wasn't lying. He really cleaned up." Yamamoto said as he and Tsuna arrived at his room. The young boss looked around curiously. He had never been to Yamamoto's room before. Gokudera and Yamamoto were usually the ones who went to his house and lounged in his room.

It looks nice. Tsuna wanted to say, but he presumed that in this world he had already been here a couple of times before. The brunet couldn't help but look at Yamamoto's baseball posters that were posted on his wall. There was cabinet full of his clothes and a shelf for his comics, baseball books, and albums, and on the corner of the room was Yamamoto's bat and baseball bag. There was also a small table in the middle of the room and a television set just right in front of it. Yamamoto's futon was just right under the windows which were open showing the beautiful view of Namimori at night.

Tsuna walked towards Yamamoto's bed and saw a small nightstand. On the nightstand was a picture frame. Tsuna picked it up curiously, forgetting that Yamamoto was just behind him.

Tsuna blushed when he stared at the picture. It was a picture of him and Yamamoto smiling at each other happily as the rain guardian held him under the cherry blossom trees.

"The baby gave me that picture a week ago." Yamamoto suddenly said. Tsuna was so shocked he almost dropped the frame.

"W-When was this?" He asked, trying to cover-up his embarrassment.

"It was the time after you confessed and I accepted your confession." Yamamoto said wistfully as he smiled. "Saa… we were really happy weren't we?"

Tsuna nodded numbly, unable to meet the other's gaze as he looked at the picture. His face in the picture was flushed pink as he smiled. What Yamamoto said was true, they were really happy there… he was really happy there…

…the whole time you and Yamamoto have been together in this world, you have been the happiest person I've ever seen. And trust me, my eyes never deceive me.

Tsuna shook his head when he heard this phrase echo in his mind. Reborn was messing with his thoughts again.

I don't like Yamamoto that way… Tsuna insisted to himself. But then he remembered the frantic pounding of his heart, the way his face flushed when the other was near…

I must be sick then… Tsuna thought. I-It doesn't necessarily mean that I'm i-in love… Many people feel that way around their best friend!

Yeah… when they're in love with that best friend… A voice that sounded suspiciously like Reborn's whispered in his head.

NO! Tsuna argued.

Say what you like. But deep in your heart you know that I'm right. The voice said in a taunt before it vanished in to the back of Tsuna's head.

You're wrong… Tsuna countered weakly as he put the frame down. Definitely, wrong…

But then Tsuna was interrupted out of his musings when he felt a familiar pair of gentle arms circling his waist. He yelped when he was pulled back into a familiar chest.

"Hey Tsuna, what's been bothering you lately?" He heard Yamamoto whisper into his ear.

"W-What?" Tsuna stuttered as his face became red. "U-Uhm, i-it's nothing."

He felt the arms around him tighten slightly. "Are you sure?"

"I-" Tsuna began, he could feel Yamamoto's worried stare behind his head. He couldn't help but sigh before he lied, "Yes, I'm sure."

There was silence. Suddenly, Yamamoto laughed softly. Tsuna froze.

"You're getting me really frustrated you know Tsuna?" Yamamoto said in his normal and cheerful tone, but Tsuna could hear the deep frustration behind the words.

"Yamamoto…" Tsuna began. The swordsman buried his face on Tsuna shoulders.

"Ever since yesterday you've been acting strange, and don't think for even a second that I didn't notice." Yamamoto mumbled softly. "I've been worried since this morning and you're not even telling me anything… Is it me? Did I do something wrong…?"

"Yamamoto…" Tsuna turned around while the other still had his arms around him. Yamamoto pulled his face back as Tsuna stared at him. "Yamamoto it's not- That's not-"

"Then what is it Tsuna?" Yamamoto said with a sigh of exasperation. "If it's not me, then what is it?"

The brunet bit his lip as his hand unconsciously gripped Yamamoto's front shirt. "I…"

"Boys… dinner's ready-!" But then Yamamoto's dad stopped when he saw Yamamoto and Tsuna. "Oops, sorry I didn't know that-… Oh well, let's pretend I saw nothing okay?" Tsuyoshi said scratching the back of his head in embarrassment as he went back down stairs. The two boys' faces exploded into red at being caught.

"Dad!" Yamamoto called out in exasperation.

"Sorry Takeshi!" His father called out, Yamamoto just sighed in frustration while Tsuna laughed uncertainly.

"Well, I guess that means we should go and eat then." Yamamoto said smiling at Tsuna. The young boss nodded while Yamamoto turned to leave. The young boss remained in his spot until Yamamoto looked up at him. "You coming?"

"Ah, just give me a second." Tsuna said as he turned his back Yamamoto for a moment. Worry flashed in the rain guardian's eyes before he nodded and proceeded downstairs. He failed to see Tsuna's face turning rapidly red because of what just happened.

The Vongola fell into a kneel as he covered his face with his hands trying desperately to get control of his rapidly racing heart.

Its Yamamoto damn it! He thought to himself as he hugged his shivering form. He couldn't understand it! He just couldn't understand why he had these types of reaction around the other!

You like Kyoko-chan! He reminded himself harshly as he tried to shake some sense into his heart. Kyoko-chan! Not Yamamoto!

Tsuna shook his head rapidly before he looked up but then he almost wished he didn't… Because the moment he looked up, the first thing that caught his eyes was the picture of him and Yamamoto under the cherry blossom tree. The brunet blushed a fierce red once more before he buried his face in his arms.

Ah yes, the signs of love…

Sometimes, don't you just wish you could control your heart for once? If you do, then you know what Tsuna's feeling right now.

A/N: Review okay? Because the more review it gets, the more interested people are to see this fan fic! And also the author get more motivated to create chapter… And I'm currently stuck with the chapter 9 of this because I haven't had any inspirations lately! D:
