Yu Gaoyi is a slightly overweight middle-aged man who chats with Lu Yanli during the subway journey. He is one of the oldest members of the group and expresses fatigue, needing to rest. After the subway stops, he and another passenger (a man wearing glasses) sit down due to exhaustion and are left behind when the group exits. They are later heard pounding on the windows and shouting for help before their screams are cut off by chewing sounds, indicating they were devoured by the subway.
