I've decided to write a bitty book of oneshots with Rin and my OC Ari. I had this floating in my head for a bit and decided to write it just because. And besides, I love my sharkie, he's so adorkable.

If Rin could count on one hand how many times Ari had come to see him at practice, he would need more fingers. Attending a girls' school that—in a way—served as a midway point to Iwatobi and Samezuka, he didn't realize bumping into her would get them this far.

Ari was the third in a trio of girls; her and her best friends Naia and Tsuki. All three knew his friends at Iwatobi first, with irrepressible Naia having an outspoken crush on Makoto. By the time Rin finally met the girls, Gou had gone to fetch him. "Why the hell did you come to get me, Gou?" he remembered asking his younger sister as she had tugged him along the way—and smacked dab into a smaller body.

Rin's eyes had widen at the sight of his friends, Nagisa flailing in concern, as Naia had her arms steadying the petite girl who was brushing her long bangs from her eyes. "Shoot, my hairclip fell out," she had muttered, shoving the thin, sakura-shaped hairclip back into her hair and securing her long bangs back into place. Gou had lost it, pleading for Rin to apologize to her.

That was when wide, hazel eyes were in his face and thin index fingers were stretching his mouth open to peer at his teeth.

"A-Ari!" Makoto had called her girl's name, the paternal nature in the gentle giant rearing its head right as Tsuki flailed with a particularly loud, "Oh my God, Ari, that's rude!"

Voice muffled due to fingers being in his mouth, Rin had asked, "What are you doing?"

"How were you born with these teeth? How does your sister not have these? What sorcery is this?" Ari had given Gou a look of pure determination, removing her fingers from Rin's mouth before announcing, "Gou Matsuoka, you have some explaining to do!"

Rin hadn't known just being around Ari was a challenge on itself, but that didn't stop him from pursuing her. Ari was the youngest of her friends, was often outspoken when necessary, and had a deep love for writing. She was always working on some project that she always kept in a binder that she absolutely let no one near until it was complete. She was a hopeless romantic, her easygoing temperament compared to his sometimes-thorny one making even his friends encourage the two to get to know each other. Even now, Rin had thought about it as he toweled himself off, water dripping from his hair and Ari had bounced down from the bleachers, her bag banging on her hip. She smiled at the maroon-haired swimmer when she reached him and Rin couldn't help himself. He reached out to tousle her hair, which had been long when they met and was cut short, the curls framing her face. "Enjoyed the view?" he asked.

Ari smiled, pushing a few curls from her face. "Of course. I came as soon as school let out. Are you hungry or anything?"

"I was just going to ask you that." Rin flicked at her forehead. "Just let me shower really quick, then we can go."

"Aye, mon ami~" She laughed, giving him a mock salute before skipping out to the hall. Shaking his head, Rin headed for the showers, not wanting to keep her waiting for even a second. When stepped into the stall, turning on the hot water to cleanse the chlorine off of him, he let his mind wander just a bit. Ever since he and Ari had started dating, Gou had constantly checked in on him with warnings of "Don't screw this up, oniisan!" Rin knew what screwing up would do. Naia and Tsuki had made it very clear they would crucify him if Ari shed a single tear because he hurt her. "But no pressure," Naia had added, with a dismissive wave of her hand.

With a sigh, he showered.

After saying his goodbyes, Rin walked into the hallway, where Ari was standing against the wall. She had a book open and was oblivious to the world. He found it a little cute. Walking to her, Rin planted his hand on top of her head, earning a surprised squeak from Ari as she looked up at him. "Ready to go?" she asked.

"I should be asking you that. What were you reading?" Rin asked as Ari closed her book and slipped it back into her bag. "Just some cheesy romance novel I borrowed from the library," she answered with a shrug.

"You're a sap for all the romance novel stuff, aren't you?" Rin began to walk toward the exit and Ari began to skip to keep up with his stride. She shrugged again, a light blush tinting her cheeks. That was all the answer Rin needed. Once they stepped outside, he reached for her hand, interlacing his fingers with hers. She looked up at him, her hazel eyes as wide as the day he first saw them—only for a different reason. It was curiosity of a different kind. "What?" she asked.

"Nothing." Rin shook his head with a soft smile as he lead the way, guiding Ari along toward a café that was just ways from Samezuka. He caught her blush darkening just slightly and his smile widened just a bit. He tugged her close to him, wrapping an arm around her waist.

"Rin? You've never been this openly affectionate since our first date to the field." Ari narrowed her eyes slightly in suspicion, yet her blushing cheeks ruined the effect of her looking stern. Chuckling, Rin drew her to him and nipped at her cheek, leaving a light bite mark. She whined a bit, pouting at him. "What was that for?"

"No reason. Just wanted to. Now come on. You're hungry, aren't you?"

"Yep!"

He shook his head again. Ari could be a handful, but Rin knew that he wouldn't change a thing about her.
