Assuming the three extremes where she has to pick between a short guy with a handsome face, a tall guy who doesn’t have a handsome face, or a guy that is neither tall nor handsome, but has dark hair, she is choosing the short guy with the handsome face.

PDA or a Public Display of Affection is perceived as a fairly controversial topic, but realistically, it isn’t.
