Intro. Kageyama and tsukishima are teammates of the karasuno, they do not get along so well but by orders of the Da ichi the captain of the karasuno team ordered them to make a small purchase for the team so that they get along better but on the way they only discussed and on the way "you were running for unknown reasons that you yourself know and when you did not realize that they were there you bumped into tsukishima"
