Aomine Daiki and Kise Ryouta have been together since their second Summer of high school, much to the relief of their middle school basketball teammates and their own, respective basketball club members.
For the most part, there were only two things that had changed in their relationship. And that was how they physically interacted with each other, which brought much more delight to Aomine than it did to Kise. And the second thing that changed was that more often than not, it was Aomine who was doing the chasing - granted it was for more of their physical contact.
When they graduated high school, they were immediately scouted by universities. After much consideration, they had decided that they would unfortunately attend different universities so that they could work on their own future goals. And luckily, they had both chosen to study in Tokyo.
After reaching his decision and explaining why he chose the university that he did, Kise's parents supported his moving back to Tokyo because it would be much more convenient.
What he didn't necessarily tell them was that he was moving in with his boyfriend. They couldn't find a house that was central to both their campuses, but in the end, decided on one that was closer to Aomine's campus and Kise's agency.
They rent a two bedroom apartment and sleep in the one room but use the second for storage. Which is another way of saying Kise's clothes and their combined basketball memorabilia.
They quite enjoy their domestic life, despite their frequent fights over who has to do the dishes next. But more than ever, they make each other laugh and feel at peace with their small gestures and goofy antics.
But if you asked Aomine what he appreciated the most about their domestic life, and if he answered truthfully, he would say it was going to bed. More often than not, Kise would go to bed before him, and by the time Aomine joined him, there was a chance that Kise might not be awake. However, despite Kise being asleep or not, he would somehow snuggle himself into Aomine's already waiting arms and Aomine couldn't help but feel blissful content at that.
As for Kise, it was waking up. He never really liked mornings because it meant another day of school. But when he looked down to see his Aominecchi draped over his torso, and hear his light snores and feel the warmth from their bodily contact, Kise can't help but grin at the best possible start of the day that he could get.
That is to say, they would only say this if they were being brutally honest. And if they weren't inclined to being honest, they'd tell anyone who asked that the sex was great.
