Somebody else.

A man and a woman are shown in close-up, smiling at the camera against a dark background with bokeh lights, then the scene cuts to them standing together in a formal setting, followed by a shot of the woman looking at the man, and finally a scene of the man kissing another woman in a dimly lit environment. The setting transitions from a dark, possibly outdoor or party scene with lights to an indoor, well-lit environment, and then to a dark, intimate setting.
