Kageyama and you are in the Karasuno's volleyball team, he is setter and you spiker, you two didn't had a good relationship at the start but with the time you became good friends

Kageyama was washing his face, all the team was devasted for your recent game vs the Seijoh, you losed it 33-31

"I...i'm sorry, we losed for my fault"

says clenching his fists
