Kise collapsed and groaned like he was dying. "Aominecchi…"
"Yeah, yeah." Aomine pulled open the fridge door and rummaged around until he found the last pack of Yakult at the back. He took one out and gave it a shake as he made his way over to the couch where Kise was flopped. "Didn't I say you'd regret that last crepe?"
"But it was so pretty, and I couldn't just throw it away after taking a picture. I'm not a sociopath. Or an influencer."
Aomine rolled his eyes and set the little thing of Yakult down on the coffee table to free up his hands. He lifted Kise straight up off the couch in a bridal carry, then spun in a semi-circle so that he could sit with Kise sprawled across his lap. All without making Kise move a muscle.
"I told you we could go back next week," Aomine pointed out. He reached past Kise to grab the Yakult, carefully peeling back the lid before passing it to Kise. "Next time, just admit you're too full. I'll finish whatever you can't."
"Yeah, but…" Kise sipped at the Yakult and hummed contentedly as Aomine started to rub his stomach. "Besides being pretty, it wasn't a very good crepe."
"Dumbass." Aomine pinched Kise's side, then went right back to soothing his stomach when Kise protested with a yelp. "Don't worry about that. It's better than you making yourself sick."
Their armchair suddenly coughed. Rather, Momoi—who was sitting in their armchair—suddenly coughed. She was staring at them like they'd each grown an extra head or two. Aomine and Kise both looked over at her.
"What?" Aomine asked.
Momoi set aside the glass of water Aomine had gotten her earlier, then rubbed at her eyes with both hands. She'd only come over after running into Aomine and Kise in Harajuku so that she could get Kise's feedback on a few new outfits she'd bought that day. She clearly hadn't expected to see… whatever she was seeing now.
"When did you two start dating?" she blurted out. "Why didn't you tell me? Dai-chan, how could you not tell me?!"
Aomine and Kise exchanged a look. When they turned back to Momoi, they were the ones staring at her like she'd mutated into something alienesque.
"We're not dating," Aomine said. "What the hell would give you that idea?"
"We're just roommates, Momocchi," Kise said.
"Ki-chan…" Momoi touched a hand to her lips. Her eyes softened with sympathy. "Oh, Ki-chan. I knew Dai-chan was an idiot, but I didn't realize it was contagious."
"Hey!" Aomine protested.
Momoi shook her head. She seemed to realize words alone wouldn't be enough to bring these big oafs to their senses. "Tell you what," she said. "Give me a week. I'll be back with irrefutable proof that you're in love with each other."
It didn't end up taking a week. Momoi spent some more time with them over the next three days, then sent them a ninety-minute compilation of videos she'd taken of the two of them engaged in what she called 'grossly romantic' activities.
And it was… pretty damning evidence.
Kise and Aomine only made it through the first fifteen minutes of the compilation before deleting it off their shared tablet in a fit of mutually-agreed-upon embarrassment.
"Aominecchi," Kise whispered, looking up at Aomine from where they were sitting—okay, maybe cuddling—on the couch. "Are you in love with me?"
Aomine flung their tablet onto the coffee table and had the decency to blush a bit. "I mean… yeah. But I didn't realize you loved me back."
Kise puffed up his cheeks. "Who says I do?"
Aomine arched a brow at him, then gave the tablet a pointed look.
Kise deflated with a big, happy grin on his lips. "Okay, fine. I obviously do," he conceded. "We're definitely going out now, then. Right?"
Aomine groaned. "Yeah. Duh. But Satsuki's gonna be insufferable when she finds out she was right."
"We can think about what we want to tell her," Kise said as he shifted to climb into Aomine's lap. "We can think really, really hard while we make out even harder. Deal?"
Aomine hooked his thumbs through Kise's belt loops and met his hooded gaze with a crooked quirk of his own lips. "I'm not enough of an idiot to say no to that. Deal."
