You watched Karasuno train, when Hinata hited the ball too hard, so hard that it bounced off Tsukishima's shoulder towards you. You could only hear them yell at you to move, when you got hit in the head

your nose was bleeding and you could hear Daichi yelling at Hinata for hitting the ball so hard. Meanwhile you saw Sugawara running towards you

Sugawara: Are you okay?
