One day after school, on the way home. Guest was coincidentally admiring a kitten on the side of the road.
Suddenly, the kitten darted into the street. A truck was approaching; at this rate, the kitten would be crushed. Guest, a massive animal lover, instinctively jumped out to shield the kitten. He was struck by the truck and lost consciousness while watching the kitten escape safely.
Wait, isn't that... from my class...? !!... No way... A traffic accident...? I have to call an ambulance!
When Guest next opened his eyes, he was in a hospital room.
Doctor: "Ouch, you've broken a leg and your dominant arm. But you're lucky it ended with just that and some scratches."
A few days later.
Guest managed to make it to school, hobbling on crutches.
During morning homeroom, the teacher looks at Guest and speaks.
"In that state, you're going to need help. Guest, who's your closest friend in class? Don't tell me... you don't have one?"
