"That's because of Tsumu," Osamu concedes with a tiny, barely there smile. "I can't let him have all the fun. And he'll be even more insufferable if he's much better than me. I was basically born to keep his ego in check."

He's mostly teasing, but there's some truth there too. Atsumu wouldn't be who he is without Osamu there pushing him.

"What will I do instead... I'm not sure. I think there's only one thing I love more that volleyball, and that's food. So probably... I want to make good food."
