Koizumi Risa (who was currently lying down on her boyfriend's bed) rolled onto her back, her long hair touching the floor from hanging upside down, and watched as Otani did his homework. "I have a question."
"What is it?" he asked, not looking up from his notebook as he wrote something down.
She smiled at him for a moment, ignoring the heavy feeling she had in her head from being upside down. Otani looked cute when he was studying or doing his homework. He would get this look of unwavering concentration. Sometimes he would stick the tip of his tongue out from the corner of his mouth when he was stuck on a certain question. Then there would be times when he would throw temper tantrums after doing the same math problem over and over and still not being able to figure it out.
A moment later he stopped, glancing at her from the corner of his eye. He raised an eyebrow. "Are you gonna ask the question, Koizumi?"
Risa jumped a bit. She laughed out of embarrassment, feeling her cheeks heat up as she rolled back onto her stomach. She waited until she settled down before asking,
"Are you ever gonna call me Risa?"
His expression became confused. "What? What do you mean?"
"I mean you've been calling me 'Koizumi' ever since we first met," she said. "We're in college now. We've been dating for almost a year. Don't you think you should call me by my first name?"
"What about you, then?" he asked. He set his pencil down and turned so he was facing her. "Why don't you call me Atsushi?"
Risa's eyes widened. "I..." She paused, not knowing how to answer.
Now that she thought about it, she never called him by his first name, either. She never even thought about it. The name Otani came so naturally to her. She didn't see him as anything else but Otani.
He smirked at her. "See, isn't it weird?"
She scowled. "What's so weird about calling me by my first name?" she snapped.
"Because I'm so used to calling you Koizumi," he replied. Smirking a bit wider, he added, "Everybody else calls you Risa. I'm not everybody else, though. I'm your boyfriend. So, to me, you're my Koizumi."
Risa felt herself blush again.
He just called her his Koizumi.
Otani smiled back, and then turned back around to finish his homework.
Inside her chest, Risa's heart did somersaults. She resisted the tempting urge to jump up and down on Otani's bed, cheering and laughing with excitement as if she had just eaten an entire bag of sugar.
She giggled softly to herself, before saying, "And you're my A-chan!"
Otani froze. He slowly turned his head to look at her, expressionless. "...What did you just call me?"
"A-chan!" she sang. "Otani is my A-chan!"
"Koizumi!" he shouted angrily, going red in the face.
Risa just laughed, rolling around on his bed and clutching her stomach as he continued to tantrum.
He'd get over it.
She was his Koizumi. He couldn't stay mad forever.
She stopped laughing and stared up at the ceiling with a dreamy sigh.
First attempt at OtaniKoizumi. I love those two :3
Anyway, hope you enjoyed it!
