Pairing: Oikawa Tooru/Kuroo Tetsurou

Rating: PG

Summary: In which Kuroo finds out who the real pun master is in his and Oikawa's relationship.

Author's Notes: Written for Writers' Inktober Day 4: Compliment. Also, extremely bad puns ahead, and the intentional use of 'complement' rather than 'compliment'. The prompt is 'compliment' but when I thought about it, all I could think of was how to use 'complement', so this happened. XD.

Kuroo remembers the first time he realized he'd fallen in love with Oikawa like it was yesterday.

It was back in their college days. They'd been hanging out in their shared dorm doing homework together, a habit they had developed soon after they'd started dating. At that time, Kuroo had known that he liked Oikawa, in fact, he really, really, liked him, but Kuroo hadn't had much of an opportunity to think beyond that. He was content to let their relationship run its course and allow for the feelings develop naturally, and Oikawa appeared to feel the same way.

After an hour into their homework session, Kuroo's interest had started to wane, and inevitably, his eyes had started to wander around the room, looking at nothing in particular until his gaze settled upon Oikawa. Unlike Kuroo, he was still fully absorbed with his assignment and looked like he was struggling a bit, if the way in which he glared down at the paper – making Kuroo wonder if the questions had insulted him somehow – was any indication.

As cute as Kuroo found Oikawa's pout to be, the look just didn't suit him, and Kuroo had the sudden urge to rectify the situation. A playful grin spread across his face when he figured out exactly how to fix it.

"You better be careful with that negative energy you're vibin'," his smile grew when Oikawa looked up from his homework and over to him, "because I am positively attracted to you."

Kuroo was more than pleased with himself when Oikawa's frown immediately morphed into the beginnings of a smirk. "Having an off day, Kuroo?" His voice was rhetorical, and he paused for a second before adding: "because your puns are more derivative than our calculus homework."

"Heh." Kuroo wasn't even the least bit fazed by the shot Oikawa had taken, on the contrary, he was elated that Oikawa decided to play along with him for once. "Speaking of derivatives, I'm having trouble with question seven. I'm starting to think I'll have to find the antiderivative of the function and substitute you in for everything."

Not the best recovery, but problems requiring u-substitutions really were all over his worksheet, and it was the best he could do while bogged down with what Kuroo had to admit, was a rather repetitive and convoluted assignment.

Oikawa simply waved him off. "Oh, I'm already passed that, and I'm working on the geometry section now." He hummed quietly as he tapped a finger to his chin in thought. "Refresh my memory please, what do you call two angles whose sum equals ninety degrees?"

"Complementary." Kuroo couldn't help but raise a questioning eyebrow in Oikawa's direction. He knew for a fact there wasn't anything about geometry in their calculus homework, and as unlikely as the notion was, he had to wonder if Oikawa had gotten the wrong assignment somehow.

"That's it!" Oikawa snapped his fingers, dismissing the look Kuroo gave him, and making him believe Oikawa had forgotten something like that, which Kuroo also found improbable.

Without warning, Oikawa's expression changed, it became softer, gentler, as if gazing at someone he was incredible fond of. On sheer instinct, Kuroo wanted to look and see if anyone was behind him, unable to shake the feeling that Oikawa was staring through him. He couldn't look away however, his eyes remained transfixed on Oikawa.

"You're my complementary angle, Kuroo," Oikawa said in a voice that was just as gracious as his smile.

Kuroo blinked, waiting for Oikawa to elaborate. When it became apparent that he was not going to give him an explanation, Kuroo tried to piece everything together, figuring he'd missed something. Surely Oikawa meant for there to be some sort of joke, but try as he might, he just wasn't getting it.

"Howdya figure?" He asked after a moment of silence, feeling rather embarrassed for not picking up on the quip like he should have.

Fortunately, Oikawa didn't seem to mind. "Because no matter how you add us together, it's always right." A small smirk played upon his lips, but the delivery was smooth and airy, as if it was only natural for him to give such a response.

For the first time in his life, Kuroo was left speechless and unable to deliver any sort of comeback. He just stared at Oikawa for the longest time, desperately trying to process what Oikawa had just said. If it weren't for the smug look Oikawa gave him that all but screamed his victory, Kuroo might not have even believed it.

But there he was, staring right back at him with an air of confidence that left Kuroo completely star-struck. In that exact moment, the affections for Oikawa that had been slowly, yet steadily brewing within him over the course of the semester skyrocketed out of control, throwing him head over heels in love, and Kuroo knew there would be no going back.

To his complete chagrin, his entire body decided to betray him, cheeks turning a highly noticeable shade of pink as his heart started to beat in such an erratic manner that Kuroo wasn't sure he'd ever calm down. To make matters even worse, he could feel the palms of his hands become clammy with sweat, accentuating the blushy mess Oikawa had so easily turned him into.

He was so embarrassed, not only because he hadn't seen it coming, but also because he couldn't find the perfect way to top Oikawa's line; by some miracle, Oikawa seemed to understand the storm of emotions causing havoc within him. Rather than giving him a snide remark about being tongue-tied, Oikawa abandoned his calculus in favor of being closer to Kuroo, moving in such a suave, elegant manner that Kuroo, in his flustered state, was supremely jealous of. He offered no resistance when Oikawa reached out and cupped his cheeks, giving him a knowing look before closing the gap between them and initiating a kiss that to this very day, gives Kuroo a tingly feeling whenever he thinks about it.

Now, Kuroo has long since accepted the fact that Oikawa is his better half in every way, especially with the superior word play that still makes him gush as much as it did back then.
