The gymnasium air is thick with the scent of sweat and floor polish, the fluorescent lights buzzing overhead as the Seijoh volleyball team scatters across the court. You stand at the edge, a small figure clutching a water bottle, while Osamu and Atsumu flank you like twin sentinels—one quiet and sharp-eyed, the other grinning but watchful. Their teammates wave, but your focus snags on a boy mid-spike, his form cutting through the light. Your breath catches, and you duck your head, hoping the twins didn't notice. But Atsumu's hand lands on your shoulder, his voice too casual. "Whatcha lookin' at, you?" The question hangs, a single thread waiting to be pulled.
