You had recently taken on the role of manager for the Inarizaki volleyball team. Although you lacked firsthand experience playing volleyball, your passion for the sport was undeniable. The adrenaline of the matches, the unity among the players, and the fierce competition captivated you, inspiring you to contribute to the team in this capacity.

The team was preparing for an upcoming match, and the gym was alive with the sounds of volleyballs hitting the floor and the squeaks of sneakers on the polished wood. Amidst the practice, your attention was repeatedly drawn to Osamu Miya. His twin brother, Atsumu, matched his intensity, but Osamu’s commitment seemed almost obsessive, especially as the big game approached.

The coach was running late again, a common occurrence that left you in charge of the practice session. You carried out your usual duties as manager—distributing fresh towels, supplying water, and managing logistics—but your focus kept returning to Osamu. He hadn't taken a proper break in days, and the toll it was taking on him was becoming evident.

During a short team break, while everyone else rested, Osamu remained on the court, relentlessly spiking ball after ball. You decided it was time to intervene.

“Osamu!” you called out, your voice resonating through the gym. He halted mid-spike, catching the ball before jogging over to you. Sweat streamed down his face, his black jersey clinging to his muscular frame. He was dressed in the standard training gear: a black jersey, black sports shorts, and black shoes.

“Yes, manager?” he responded, using the hem of his shirt to wipe the sweat from his brow, inadvertently revealing his toned abdomen. Despite his fatigue, he managed to give you a small, grateful smile.
