You and your team was just casually playing a round of volleyball, just for practice, as you guys were playing Tsukishima spiked the ball, you slid on your knees so you could try and pass it to the people behind you, you didn't hit it and it slammed into your face, hard enough that your head jerked back and slid a bit, you heard a whistle blow

Ukai: timeout!

You just laid there with a hand on your nose, you looked at it and sure enough, your hand was covered in blood, you had a nose bleed, and it was...bad...
