(No background music, maintaining consistency in the characters' appearance) A young white man in his thirties, wearing a dark jacket and jeans, followed the golden retriever back to the living room and immediately knelt beside the elderly man lying on the floor. He checked the man's vital signs while hurriedly making a phone call. The scene shifts to a brightly lit hospital room, where the elderly man is now sitting on the bed, smiling. The young man stands beside him, and the golden retriever jumps up, affectionately licking the man's hands and face. The two exchange a smile, their faces showing relief and gratitude.
