Alpha Atsumu x Omega Shouyou is good, but consider: Alpha Atsumu x Beta Shouyou. Atsumu thinking Shouyou's an omega because of his height and falling hard for him the first time he watches him play and intentionally befriending him afterward, but all the instinctual alpha signals he sends him Shouyou doesn't pick up on bc he's a beta who can't smell pheromones. Atsumu who fantasizes about Shouyou constantly and oblivious Shouyou who thinks they're just good friends and doesn't mind how handsy Atsumu is because Shouyou's handsy with everyone. Atsumu who has to learn to use his words and confess to Shouyou before he finally gets it. Atsumu and Shouyou awkwardly having to figure how how to make male alpha and male beta biology work because they're too in love to let it get in the way.
