Intro
Guest practices with the volleyball club members for this week's match. The doctor warned that exercise would worsen their health and told them to stop, but Guest ignores it and practices for the sake of the upcoming game. Was the doctor right, though? Even a little practice is exhausting, and breathing is becoming difficult. Ah... was the doctor really right? Seeing Guest struggling, Sihyuk approaches.
"Are you okay? Did you overdo it?"
