vi. math is important!
Aoi grimaced to herself as the teacher wrote their math homework on the board—ten pages worth of work due by the end of the week. Math was arguably her worst subject, and it showed in the marks. This year's university entrance exams were coming up too soon for comfort, and she knew she would have to study extremely hard just to even pass the math component.
"Man," Aoi groaned to Iwaizumi and Yui as a ten minute break started—English was next, and though it was hard, she preferred it to math. She took a potato chip snack out of her bag and ripped it open, popping a chip into her mouth. "I hate math. What's the point of it, anyway? It's not like we'll actually need it in real life unless we take pure math in uni."
"That's not true," Yui argued. "Math is super important! Right, Iwaizumi-san?"
Iwaizumi shrugged. "I guess. It's not my favorite subject either, so I don't really have an opinion on it."
"Really? What are you gonna do after high school?"
"I'm not really sure yet."
"My point still stands," Aoi said, a little haughtily. "Math is virtually useless in the real world!"
Pouting, Yui shot back, "Like learning about ancient history is useful!"
"It is useful. 'Those who do not read history are doomed to repeat it'. Santayana George."
"Stop quoting obscure authors!" Angrily, Yui bit into her chocolate taiyaki.
"Ah." Iwaizumi blinked, hand moving to her face. "You have some on your cheek."
Blushing, Yui wiped her face, completely missing the chocolate stain. "Is it gone?"
"It's still there. I'll get it for you."
Oh, Yui, Aoi sighed internally, trying not to smile as Iwaizumi wiped off the chocolate with the pad of his thumb. You're so smitten with him. Her cat-like gaze shifted to Iwaizumi, who seemed to be fighting off the urge to stare at her. Poor boy. You've reeled him in so bad. "Well then," she said loudly, making them both turn to her. "If you think math is so important, Okayui-chan, then prove it."
"Fine!" Yui harrumphed. "Just you wait!"
It was around eleven-thirty that night when Aoi received a photo from her friend. At first, she squinted, unsure of what it was. But then Yui texted a follow-up, and Aoi couldn't help but burst out in laughter.
[Okayuki]: I found a hair in the shower, blew it aside, and it landed on the wall like a cos curve.
Biting her lip to try and contain another laugh, Aoi dialed her number. "Hello? Okayui-chan?"
"Minacchi!"
"A hair shaped like a cos curve?! Is that the best you can do?!"
"Shut up! Stop laughing!"
"Oh my god, Okayui-chan! Bahaha!"
Across the line, Yui huffed. "I'm hanging up."
"No, wait!"
"Yeah?"
"Can you help me study for math?" She muffled a giggle. "I'm sorry I laughed at you."
She could picture perfectly Yui's pout. "... Yeah, okay."
