A new fanfic at last. It was so hard to decide which story should I write first. I have too many ideas and to little time to write. duh. There are not so many stories about Shiraishi so I decided to make this story first. The reason why I use this title is still secret. I'll tell you later, in the last chapter ;)

disclaimer: I own neither the Prince of Tennis series nor its characters. I just own my OC, the first aid kits box, the reference book, and the bed.

This chapter is most likely dedicated to my best friend. She wants me to write a song fic of one of Shiraishi's songs but.. dunno.. I think she should wait a little longer till I have more confident to write a song fic.

I'm sorry for any grammatical error, my English isn't perfect.

Anyway, thanks for dropping by. Enjoy reading :D

Ch1: fifteen - love

Who didn't know Shiraishi Kuranosuke? The perfect genius who had no flaw both in class and on the tennis court. One of Shitenhouji's best tennis players who was entrusted to bear the captain title for 2 years in a row. Shitenhouji's bible who once again led his team mates to the national championship.

Everyone knew him, at least, everyone in Shitenhouji Chuu. He was respected both by the teachers and by other students. He was also very popular among the female students. It was said that he even had his own fan club.

He was really nice, athletic, smart, and deadly handsome. In short: perfect. It wasn't hard to fall in love with him.

Among the girls who adored him, there was a girl who had a crush on him ever since they had been on the first grade, ever since their first meetings when they had joined the heath care committee. Her name was Oshitari Kouki. Together with her cousin Kenya, who regularly visited the infirmary, they spent time happily as friends. She never intent to tell her felling to Shiraishi. Spending time with his as friend was so great; she didn't dare to ruin everything she had right now. That was she thought, Until one day Kenya's words stroke both her heart and her mind.

"How long do you intend to keep this kind of situation?"

"Huh?" Kouki, who had been arranging the medicine in first aid kits box for a while, stopped and looked at Kenya with confused face.

"About Shiraishi." Kenya began to explain. He was lying lazily in one of the beds with 'How to give first aid' reference book in his hand. There was nobody else in the infirmary room beside him and his cousin. "I know you like him. Have you ever thought about confessing your feeling to him?"

Kouki stared at Kenya for a while and gave him a short answer. "No."

"Why?"

"Just no."

Kenya got up and approached her. "C'mon! You two have known each other for more that two years. What you took so long?"

She ignored him and started arranging the medicine again.

"Hey!" Kenya shouted in annoyance.

Kouki merely sighed and stood up, facing her cousin. She was still shorter by 15 centimeters than him even she was standing now. Her dark grey eyes stared at him white his also stared back.

"What do you want?" She asked.

"Uhm, helping you out?" Kenya shrugged with sheepish smile.

"Then you can brag about it to Yuu-chan?" She asked again with skeptical face.

"Of cou-, wait, that's not the point!" Kenya tried to defend. He felt uneasy when Kouki looked him with oh-so-that's-what-you've-been-thinking-of look.

"Then?"

"Well," Kenya made a couch like sound as he looked away. "Won't it be great if my best friend starts dating my beloved cousin?"

Kouki still stared at him.

"Anyway, we're graduating soon. You should make a quick step or you'll lose him forever." He added.

She was about to talk back when suddenly the door opened. It was Shiraishi.

"Yo!" He greeted the blonde head and the black head.

"Yo Shiraishi!" Kenya greeted him back as they did a high-five.

"What are you doing here, Kenya?" Shiraishi asked to the speed star.

Kenya grinned. "Just taking a short nap after my second bento."

"You'll get fat!" Shiraishi teased, playfully smacked his best friend's chest.

"No way!" Kenya smacked back.

Shiraishi chuckled, which Kouki found to be soooo adorable. "Isn't it time for you to go to the broadcasting?"

"Don't worry. It'll only take 30 second to get there. I still have a lot of time." Kenya bragged.

"That's our speed star." Shiraishi laughed as he walked towards the bed that Kenya had been used before and started to tidy it up.

"I think you better go now. It's forbidden to run in the corridor right? I suggested you take a slow peaceful walk." Kouki teased.

"So that you'll be leave alone with him?" Kenya successfully teased her back, making her pout with blushing checks.

Kouki glanced at Shiraishi. She thanked God he didn't heard their small conversation. Seemed that he was to busy with his work. Without realizing, she was now watching him instead of taking a short glance. He tidied up the bed with no useless movement as usual. 'That's so Shiraishi.' She thought.

Some moment later Shiraishi had finished the tidying up and he sat on the bed, mumbling What a hot day as he loosen his shirt's upper button, much for showing some skin and Kouki felt that she was going to nosebleed.

"Pervert." Kenya whispered at her ear.

Kouki jumped a little in surprised. Her face was completely red now.

Kenya burst into laughed. "Haha.. What were you thinking about just now?"

Kouki became speechless, didn't know what to say against him. Oh, she did staring at Shiraishi and she knew she couldn't deny it.

"What's wrong?" Shiraishi approached the Oshitaris. He looked at Kenya. The laughter must have gained his attention.

"Pfft. No- nothing." Kenya tried to stop laughing, but he failed.

Shiraishi turned to Kouki, Seeing her couldn't-be-hidden red face, he asked worriedly. "Kouki-chan? Your face is so red. Are you sick?"

He placed his hand on her forehead. Now she could feel her face was burning even more. His eyes stared worriedly at hers. She felt her heart stopped beating as they eyes met.

"Kouki-chan?" Shiraishi asked again. Kenya tried his best not to laugh at his cousin, at least, not now.

"I- I'm okay." She replied, finally fining back her voice. She stepped back a moment later, turned away and ran lout of the infirmary, leaving the confused Shiraishi and Kenya, who was still trying his best not to laugh.

"What's going with her?" Shiraishi asked to Kenya as Kouki's long wavy hair disappeared behind the door.

"Fifteen – love for you, I think. Oh, don't worry about her. She's perfectly fine. Just a bit sick." He giggled, and then added in very soft voice. "Love sick."

"Huh?"

"Uh-huh. Gotta go now," Kenya looked at his watch. "See ya later." He waved then dashed out of the room.

"Weirdo." Shiraishi commented as he was left behind alone. "What's with that fifteen - love?"

Kouki walked slowly in the corridor. She had stopped running a while ago and her face had retuned to its normal color. She was now thinking about Kenya's words back then…

"Anyway, we're graduating soon. You should make a quick step or you'll lose him forever."

That's it. Kinda short isn't it? This chapter is much like an introduction. At least now you know what she looks like.. (Or not?) I'll write more on next chapter. And sorry if Shiraishi and Kenya are kinda OOC.

I try to make a different kind of canonxoc story. I made the OC is already in love with him. What do you think?

Again, thanks for reading. See you on the next chapter!
