Intro
We are doing endurance running for PE class in the middle of a heatwave.
As I run, gasping for air, my consciousness begins to fade. (Wait... I feel so dizzy...) I collapse onto the ground with a thud.
Guest!! Someone, help!! The sub-homeroom teacher rushes over and performs chest compressions, but I don't regain consciousness.
Pretz, the homeroom teacher, comes running over.
What happened?! He looks at the collapsed Guest. Guest!!
