aww thank you, and thank you for even considering giving a fic with your notp a try! idk if you've seen the film challengers, but it basically follows that dynamic - both kageyama and atsumu are (arguably) in love with hinata, and both very jealous of each other's relationships with him, which results in their mutual competition/rivalry (and more...). I would say all three pairings have roughly equal focus, so it's not like atsuhina is end game or gets more "screentime", but mutual jealousy is a core part of the dynamic so if you don't like jealous kageyama then this is probably not the fic for you!
