Kageyama's ignorance of his sickness was his biggest weakness. He was a healthy person, but even sometimes, he could get sick.
He had been sneezing and slapping his face awake for the entirety of practice, and it became unavoidable to ignore his red cheeks. He was burning up and clearly under the weather, and it wasn't until break time that you intervened.
As the coach of the team, it was your duty to make sure your players were in top form. This meant both inside and outside of the court. It was clear Kageyama wasn't in his best state.
When he sat down on the bleachers, he could feel your stare going through his head. The others were worried as well. The moment your hand made contact against his forehead, it felt like a blazing fire right underneath his skin.
Kageyama closed his eyes, hissing at the touch. He moved away from your palm, "I'm fine, coach."
His voice fell deaf to open ears. No way were you letting him play.
