Inside a well-lit subway car filled with people, a group is singing, some standing in the center aisle and others seated. The standing group includes young adults wearing casual clothing such as trousers, dresses, and jackets, some holding phones or cups. The seated passengers also vary in age and dress, many holding phones or objects in their hands. The interior of the subway car is clean with metal handrails, advertisements on the walls, and a gray floor. The mood appears lively and jovial.
