okay here is the pairing: Aomine x Kise ( * v * )
CRIES WHY WOULD YOU DO THIS TO ME
Ok, ok. Lemme think of something LESS angsty than I did for the other one.
Completely disregarding Aomine’s love for Kuroko and only being really close friends with him, he slowly starts to develop feelings for Kise due to Kise’s admiration for him. Since Kise started basketball because of Aomine, Aomine can’t help but feel quite prideful over it.
Seeing Kise being close to Kasamatsu or even his fangirls, Aomine can’t help but ALSO feel irritated yet doesn’t know what he is feeling because he is dense in that situation. And in order to remedy the feeling, he purposefully hurts Kise by doing things like slinging his arm around Kuroko. Of course, he initially feels good until he sees Kise’s sad hurt puppy face and then feels worse afterwards. Basically, they both use Kuroko as a means of making the other jealous which in turn irritates Kuroko because holy cow can these two just kiss each other already?!
As for Kise, he’s always, always been in love with Aomine but only realizes it when his fangirls poke into his love life and ask him who he likes. I can imagine a question like “Is there someone that pops up every time you try to think of someone you love?” So they are both very dense when it comes to their love for one another.
I can see the two of them getting together ONLY after their epic match against each other though.
