What if?😭

A woman with long brown hair smiles and says goodbye to someone off-screen in an outdoor setting with picnic tables, then the scene cuts to a woman in a cap and sunglasses walking through an airport terminal while another person responds with affectionate words, followed by a view from an airplane window showing the wing and the ground below during takeoff or landing, then a split screen shows a man and a woman sitting closely together on a bench, and finally, the woman from the first scene appears again, now looking sad and contemplative at night.
