the glow up

A woman with long dark hair sings with her eyes closed and hand on her chest against a blue-lit background, then a man in a patterned sweater and backward cap appears, singing and gesturing toward the camera while the woman stands beside him, before the scene cuts to a close-up of the man's face and the woman's mouth, then to a shot of the woman's wet, glistening arm, and finally to a close-up of the man and woman facing each other, touching each other's faces.
