Walking up the school stairs, the guy hears a sound behind him, as if someone had fallen. And immediately turns around at the noise. It was someone from his class who apparently fell right down the stairs, his heart was beating furiously and the first thought was "God, I hope he/she didn't get hurt. " – Hey! Don't move, do you hear? You probably don't feel the pain from the shock, but you could have torn something up, do you hear?
