((Seijuurou should've thought this through more

Or: Shit, you're actually good at swimming, this wasn't part of the plan

This is because plot bunnies clung to a headcanon that said that Gou actually swam really well, she just chose not to. And then I wanted to write seigou and well, the rest was history. (New) Title from NeverShoutNever's "Trouble", which is my SeiGou song like omg, please listen to it. Just go listen to I Love You 5 and Can't Stand It (Same singer) and feel seigou with me))

"Hey Gou-kun!" He had luckily caught her when she wasn't surrounded by her overprotective entourage.

She rolled her eyes, not even bothering to correct her name, "Yes, Mikoshiba-san?"

"Race me! If I win then you have to go on a date with me, okay?"

She thought it over and he worried she'd say no. The plan was simple enough; he'd purposely lose to boost her ego and then, when she felt her best, he would ask her out and she'd say yes, no longer able to resist his charm and good looks.

"Sure," She said finally, a small smile playing on her lips "But you better not go easy on me because I'm a girl."

"Oh no," he assured her even as he thought the opposite, "I'd never think of it."

He honestly should've known better.

It didn't matter that Gou was two years his junior, he still should have at least anticipated that she - the sister of a guy who broke a school record in his tryout - would be a good swimmer. But no, he hadn't thought that far ahead when he challenged her to a race.

He should've been more concerned when she showed up about thirty minutes before Samezuka practice would start, their agreed race time, in impressively professional-looking swim gear, but he was too busy thinking about how pretty she was to worry.

Mental alarms should've been going off when she began asking Nitori - the assigned countdown person, who had been sworn to secrecy about the date part - questions about what kind of race it was, how many laps they were doing, serious race stuff, that he didn't even have to dumb down for her. According the plan, she was supposed to only have a vague knowledge of how swimming races went, because while he knew she was Iwatobi's manager, he didn't think she actually did anything besides schedule joint practices and yell at her team every now and then.

His final warning should've been when he noticed the same flash of determination that Matsuoka got before he faced off with the Nanase kid, but he ignored it and believed in his plan.

But, as he soon realized, Gou wasn't just cute. As soon as they were off the block, he could see her out of the corner of his eye, executing a front crawl that could probably rival that of half his team. He had started out slow because he was convinced that sticking to the plan was the way to go and by the time he began to correct his mistake, she had too much of a lead. His stomach twisted as he saw her finish her laps, even if he was only a second behind her, and not just because she looked absolutely adorable smirking like that.

"Took you long enough," her smirk grew as he rested against the pool wall, clearly out of breath. "I mean, I expected you to do something stupid like let me win, but I thought that you'd be able to keep up for the most part."

That was the plan, Seijuurou thought dejectedly, but he tried to play it off with a grin, even if the deep gasps between every other word sort of ruined the effect. "Who's saying I didn't let you win? I never could've beat me if I tried."

Gou giggled, a sound more beautiful as anything Seijuurou had ever heard, "Whatever you say, Mikoshiba-san."

He pouted as he climbed out of the pool, thanking Nitori for the offered towel, and dried his dripping hair off. His ego was severely hurt, because even if the way Gou looked at his considerably nice muscles made him feel slightly better, the plan had gone completely wrong and he'd made a fool of himself.

"So, for our date I was thinking we should get pizza. I know just the place, and I might be able to bribe a friend into getting us a discount." Gou's voice brought him out of his dreary thoughts.

"Wh-what?"

"I said," Gou sighed in exasperation, "we should get pizza for our date."

"Our date?" Seijuurou blinked owlishly, "But... I lost."

"Yeah, you did. The rules were that if you won, I'd go on a date with you. Since I won, you're going on a date with me and I get to pick all the details," Gou was resolute in her explanation, and he would've been fooled by her matter-of-fact demeanor if not for the light pink blush that decorated her cheeks.

Seijuurou turned deep red, resisting the urge to pinch himself to make sure he wasn't dreaming. "You still want to go out?"

"Obviously. Didn't I already say that?" She rolled her eyes and handed him a pen, "Write your email down, I'll message you the specifics sometime this week."

He could only dumbly nod as he scribbled the words on her outstretched hand, still not quite comprehending the sudden turn of events but quite okay with them anyway.

"Well, I should get going or I won't get back to Iwatobi in time and the boys will start to worry, but I'll text you." Gou smiled that cute smile of hers, and his heart fluttered painfully in his chest, " Goodbye Seijuurou-kun."

"Uh, yeah! See ya, Gou-kun!"

And the second she was out of sight, Seijuurou began the dorkiest victory dance known to man.

"Captain, please stop that," Nitori sighed beside him, "It's embarrassing."

Seijuurou just grinned, not caring if any of his teammates saw him, because in a contorted version of his plan, it had all worked out and he had a date with the cutest girl ever.

((Edited 10/6/14 because this is a year old and, while I didn't cringe while looking at it, it was still pretty bad. Also because I wanted to add in some Nitori because none of you are my mom.))
