This one's about Sengoku and Kirihara. NO YAOI! I love Sengoku and Kirihara as STRAIGHT individuals. Anyway, please enjoy.

Fly High, Mister Mathematician!

It was a boring Saturday afternoon; at least it was for Akaya Kirihara. He had nothing to do. There was no training, as Yukimura went to the hospital for his monthly check-up, together with Sanada. The other Rikkai members were doing their own thing. So, he took his mighty cellphone out and pressed the address book button. He scrolled down the names and there he saw Sengoku Kiyosumi. He contacted the said guy…

And by doing so, here he was, at Sengoku's home, watching the latter answer a series of quadratic functions, or for Kirihara, sentences with both numbers and alphabets in it.

He was sitting on a chair beside Sengoku, who was chewing on the tip of his pencil. He was staring at the paper seriously, as if the existence of human beings depended on his ability to answer the darn paper. Kirihara groaned.

"I didn't know you were a freak." Kirihara said.

Sengoku didn't budge. He still remained the nerd he was. His indifference irritated Kirihara.

"Hello!? Earth to Sengoku!"

Sengoku was surprised. He looked at his visitor, an innocent surprised look marring his face. Kirihara crossed his arms on his chest. Sengoku placed his pencil on top of his paper.

"Wh-What? What is it?" Sengoku said. Kirihara narrowed his eyes at him. This made Sengoku frown.

"What? Is something wrong?"

"Nothing much." Kirihara said. "Of all people, I didn't expect YOU to be a math nerd."

"Hey, I'm not a nerd!" Sengoku said defensively. "I'm just trying to answer an assignment, that's all!" Sengoku then focused once again on his assignment. His thinking look marred his face the second time around.

Kirihara scratched his head.

"I shouldn't have come!" he said. "You said you had a fun activity to share!"

"Yes, I have!" Sengoku looks at him and grins. "And it's answering an assignment. Cool, huh?" Sengoku innocently grinned at him.

A vein popped on Kirihara's head almost instantly. His brow started to twitch.

And you say you're not a nerd…Kirihara thought.

"Honestly, I thought you were the type of guy who drowns himself with hundreds of cellphone numbers of women, but no, you choose to answer this…this…pathetic excuse for fun!" Kirihara said.

"I like women." Sengoku clarified. "It's hard, having bad luck with girls. I don't get it sometimes, you know!? Thank God for my luck at Tennis though!"

At that, Sengoku grinned and he continued to stare at his assignment. Soon enough, he was simplifying four quadratic equations swiftly.

"I will never know the feeling. Back at Rikkai, our team was always fawned over by women, Captain and Marui having the highest number of fan club members." Kirihara started to narrate. Sengoku nodded his head as a sign of listening. He was still scribbling answers.

"I hated those annoying women! They get so crazy, I tell you! Once, there was this third year who tried to sneak inside the showers while Captain was taking a shower! If she wasn't a girl, Vice Captain Sanada would have hit her, I tell you! It was crazy but Captain forgave the girl. Turns out, that girl was the president of his fan club!" Kirihara narrated, snorting in the process.

Sengoku chuckled at the story. He was still answering though.

Several silent moments passed. Out of boredom, Kirihara stared at the walls of Sengoku's room while the latter continued to answer his life's satisfaction.

Why the heck did he choose yellow paint for his room walls? God, it looks so messy!" Kirihara thought.

Kirihara was about to ask Sengoku regarding his tastes in wall color when suddenly…

"Hey, Kirihara…"

Kirihara looked at the nerd beside him. He was surprised when the latter grinned at him.

"Hmm? What do you need, dork?"

"I was wondering…"

Kirihara was surprised when suddenly, Sengoku shoved the paper flat on his face. This was followed by another one of Sengoku's grins.

"Do you know how to simplify the fifth quadratic function? I really don't get it at all!"

Kirihara sighed.

"Technically, you are my senpai. I'm in 2nd year and it's virtually impossible for me to know how to simplify quadratic equations."

Sengoku laughed. He then scratched his head.

"Of course! How could I forget?"

Sengoku was about to analyze the last quadratic function when suddenly…

"Although…."

Sengoku stared at Kirihara. Kirihara smirked.

"I forgot to tell you. I take Advanced Algebra as my elective…"

"Then that means…?"

"Yup!" Kirihara said. "I'm actually every bit the dork you are!"

The two eventually laughed. Kirihara started to teach Sengoku how to answer the last problem. While Sengoku was scribbling the answers, Kirihara asked.

"I was wondering…"

"Yes, geek?" Sengoku inquired with a grin.

"Yellow looks icky. Why did you choose it as your wall color?"

OWARI

I had fun writing this one! See? Kirihara and Sengoku can get along fine as straight individuals. But that's just my opinion. Hope you enjoyed!
