Be my coach! [Iwaizumi Hajime // Post Time skip]

Prologue

Iwaizumi hated children.
It wasn't just small children but any human being that happened to be younger than eighteen years old.

Maybe it was the fact that he couldn't deal with children even if his life depended on it — not that he'd admit he was short tempered and possibly just as immature as them.

"Come on." Oikawa whined while holding tightly onto the half empty glass of beer. "Don't tell me you can't handle teaching teenagers rather than grown men?"

Iwaizumi rolled his eyes and his eyebrows furrowed as he glared at Oikawa.

"It's not that I can't handle it." He mumbled and chugged down the beer in his cup before continuing. "You know how immature high schoolers can be — I don't even know how our own coach handled us back then."

Oikawa laughed in response to his words.

"It'll be fun." He said while giving Iwaizumi a light punch on the arm. "Your team will be on break from their next championship until the next Olympic games — it's not like you can't take a few months off to help them out."

"If you think it's so fun you should do it." He snarked.

"I'm not the athletic trainer here." He replied with a condescending smirk. "But fine — you're no fun. You've always been so uptight — never out of your comfort zone ever."

Iwaizumi rolled his eyes — mainly because of that fact that what Oikawa had said was right and he couldn't argue with him.

He sighed deeply before finally speaking in a defeated tone.

"What's... the pay?" He questioned, pinching his nose bridge in distress.

"It's nothing compared to your current salary but just think of the smiles on those boys's faces — just like us back in highschool." He said as he rummaged through his pockets to find a small flyer with the number of the highschool he was talking about.

"I'll give it a try." He said with a groan. "I guess if I train these kids I might even get better at training the guys."

"That's the spirit!" Oikawa chimed with a bright smile. "For that, I'll even pay another round of drinks."

Iwaizumi rolled his eyes and shook his eyes in disbelief but faintly smiled as his friend urged to call the waitress again.
