A/N: So I've been obsessed with this pairing lately after watching Reborn! for the first time two weeks ago. And honestly? I don't have any of the stories marked purple because I read almost all of them! Now I have at least five in my favorite stories list and a stash of doujinshi in my computer because of it... I think I'm in love!

If you're a Haruhi Suzumiya fan, you can obviously see where I got the title from. Haha.

And I also borrowed some of the elements of the story (like the song idea) from Kids on the Slope, another anime I have come to love. Seriously, a bromance AND jazz music? What's not to love? Anyway...

Disclaimer: I do not own Reborn! or any of its characters.

1. My Favorite Things

That bright and sunny Wednesday morning had been just like any other, except with one tiny difference, the tune that hung in the air that no one other than Takeshi Yamamoto was humming.

"My Favorite Things?" Tsuna asked Yamamoto as they walked to school. Gokudera went ahead of them, muttering something about running from Bianchi before she saw him. At the question, Yamamoto looked at him sheepishly and smiled.

Yamamoto laughed, "So you heard that, huh? That song has been stuck in my head all day yesterday and all this morning while I was getting ready."

Tsuna smiled as his taller friend, "Ah, yeah, I did. That song was one of my favorites when I was younger."

Yamamoto stared back wide eyed, "You, too?" he yelled.

Tsuna laughed, "Yeah, when I was a kid. My mother told me that I used to watch the movie every day. I used to drag my dad to watch it with me, too, whenever he came home from work."

Yamamoto laughed, "Is that so? It sounds like you had a nice childhood."

Tsuna looked away from Yamamoto, smile still on his face, "I guess so."

The two boys walked in silence, but Yamamoto's sunny disposition would not fade, realizing that he was learning more about his friend through each and every passing day.

That afternoon, Yamamoto decided to do his homework at Tsuna's house, and he was greeted by his mother at the door.

"Oh! Takeshi-kun!" Nana exclaimed, ushering Yamamoto into the house, "Tsu-kun is in the basement, he hasn't been out since he came home from school! Can you go get him so he can work on his school work? He has been down there for much too long!"

"Eh? You guys have your own basement?" Yamamoto asked.

Nana nodded, "Yeah, it used to be Tsu-kun's play room when he was younger. It's down the hall near the bathroom, I need to go and finish making dinner, don't make too much noise, okay?" Nana further pushed Yamamoto into the hallway, and disappeared into the kitchen.

Yamamoto scratched his head and opened the last door at the end of the hallway, where his ears met a piano.

'Radio?' Yamamoto thought to himself, and he recognized the song right away, "My Favorite Things". 'Ah', he thought as he went down the stairs, 'I must have gotten it in his head, too.'

The music, in fact, did not come from a radio, or a CD, but it was Tsuna himself, playing on a worn out piano on the far side of the room, with Reborn watching from a chair drinking coffee. But, the song seemed… different, somehow, Yamamoto noticed. It was the same song, for sure, but the rhythms were just off by a tiny bit, as though Tsuna was making it a different style altogether, like it was a jazz song. Never the less, Yamamoto found himself intrigued by the fact that his friend played at all.

From where he stood at the bottom of the stairs, he only saw Tsuna's back as he played the piano with an incredible amount of concentration. Then, his heart did something that he would never understand, it skipped a beat. This act made him clutch his chest, what was happening to him?

"Oi, Tsuna," Reborn said after sipping his coffee, "You can't even play a simple song right."

Tsuna rubbed the back of his head, "I know, I know. My mom always said that I was more of a jazz player than an actual pianist." Yamamoto saw his friend laugh a bit, a light blush covering his face.

"I thought it was wonderful," Yamamoto said before he can stop himself, and the moment the words left his mouth he had to fight the urge to put his foot in his mouth.

"O-oh! Yamamoto!" Tsuna said before he hid his face, "I didn't know you were here. So, you heard me, huh?"

Yamamoto nodded, "I didn't know you could play, Tsuna."

Tsuna laughed, turning a darker shade of pink, "I used to, a long time ago. But my teacher kept yelling at me because I couldn't get anything right. so I just stopped. I don't think i would be as good as Gokudera-kun, anyhow. He's amazing."

"Well, I think you should keep playing, I think you have your own style, Tsuna. I think you're an amazing piano player," Yamamoto said with his trademark grin. Honestly, if he kept smiling more like that he was going to have to copyright it!

Tsuna looked behind him, and looked Yamamoto square in the eyes, where his shock was soon softened into kindness and appreciation. "Thank you, Yamamoto!" he said with the brightest smile.

The sight made Yamamoto's cheeks redden. Seriously, what was happening to him? "O-oh, Tsuna, it's no problem, just saying it how it is," Yamamoto said, laughing nervously. "Your mother said you were down here, and I was wondering if you wanted to work on homework together or something."

"Sure! Oh! Before I forget…" Tsuna said then got up to a table in the middle of the room, picking up something shiny. "I found this in our old DVD pile, I was planning on watching this while working, but since you're here, we can watch it together!" He flashed a copy of The Sound of Music at the baseball player, the cover slightly dusty.

"Make sure you finish your homework though, Dame-Tsuna," Reborn advised.

"We will, we will, Reborn. So how about it, Yamamoto?" the mafia boss asked, and all Yamamoto could do was smile and nod.

"Sure, let's go, Tsuna."

Needless to say, the two boys took a lot longer to finish their homework that day.

A/N: So that's it so far... I was planning on making this into a huge one shot but I figured I should take my time on it... Please review!
