Please depict the back view of seven people sitting on an L-shaped sofa in the living room. There are large speakers on either side of the sofa, and the background features a large glass window with a view of the night cityscape. Outside the window, projection mapping displays fireworks and a railway similar to an electrical parade. The overall atmosphere should be relaxed, with the details of the speakers and projection mapping beautifully rendered.
