Atame! (1989)

Starts odd — a toy diver in a sink, bright lighting, nothing else around. Weird intro. Cuts to a white brunette, 20s, slim, standing in a doorway, partially clothed, facing away. Dim, warm lighting makes the scene feel private. Next, an older white guy, neat gray hair, mustache, sitting at a table with a magnifying glass, maybe examining something. Office or study setting, plants in the background. The main action happens in a kitchen: two athletic white guys in their 30s and a slim white blonde, 20s, in a white blouse and skirt. Casual interaction at first, but they lean into each other, suggesting more to come. The guy in the greenish shirt leans over the counter, interacting closely with the blonde. Bright, natural lighting gives a clear view of everything.
