"Hayato?"
Gokudera looked up from is book to be assaulted by large brown eyes in front of his.
"What?"
Yamamoto pouted from his place on the floor. "You promised to celebrate the New Year's with me, but all you're doing is reading your book."
"It's not just a book, idiot. It's The Universe in a Nutshell by Stephen Hawkings."
The rain guardian gave him a goofy grin. "Silly Hayato! The universe wouldn't even fit in a baseball, and everyone knows baseballs are bigger than nuts!"
Gokudera resisted the urge to face palm. "Never mind. Someone like you wouldn't understand."
He turned his attention back to the book, settling down once more into the couch.

Yamamoto frowned. He didn't get it. Someone like him? Did Gokudera mean baseball players? Maybe baseball players wouldn't understand because they're smart enough to know that the universe wouldn't fit in a baseball, and that baseballs were bigger than nuts. That must be it, right? It only made sense to Yamamoto.

Yamamoto propped his chin up on Gokudera's knee. Thinking made his head hurt.
"Hayato! Did you know that couples who kiss at midnight on New Year's will stay together forever?"
Gokudera looked down at him, a silver eyebrow arched. "Are you implying that we're a couple?"
"Of course we are! We're spending New Year's together, aren't we?"
Gokudera rolled his eyes. "Plenty of non-couples do that."
"We kiss too! And you really like it when I tou-"
"Shut up! I get it!" His face burned red. "We're a couple! Happy?"
If Yamamoto had a tail, it would've been wagging.
"I love you, Hayato!"
"Fuck you."

Yamamoto went on grinning like a (baseball) idiot, and Gokudera did his best to ignore him. The night went on, the only sound the ticking of the tacky baseball clock that hung on Yamamoto's wall. Yamamoto eventually felt his eyelids droop and yawned so hard he thought his face would split in two. Leaning forward, he rested his chin on Gokudera's knee again, gazing at his lover behind the book. Said man looked up and glared.
"What're you looking at?"
Yamamoto grinned. "Hayato's pretty face~"
"My what?"
Before Yamamoto could say more, a loud voice cut through the room.

"Hooooooome run!"

Yamamoto perked up. "Oh! It's midnight!" His eyes sparkled. "Happy New Year's, Hayato!"
Before he could comprehend what was happening, the collar of his shirt was yanked forward. Lips smashed against his in a bruising kiss. But as quickly as it happened, the lips were gone.
"H-Hayato?" He asked, shocked.
"S-shut up! Don't think it m-meant anything!"
Yamamoto looked liked someone just told him he won a thousand baseballs.
"Does this mean you want to stay together forever?"
Gokudera flushed a color to match his flame. "D-don't put it like that, idiot!"
Yamamoto jumped the other, crushing him in a hug.
"I love you, Hayato!"
"F-fuck you…"

Due to popular demand, I nixed the ending, which in the end kinda made me happy, cuz it's been bugging me :/

And I was thinking, how annoying would it be to have a clock that says "Home run!" every night at midnight? I think I'd shoot myself :P

But Happy New Year's everybody! :D
