A guy lying belly-down in a swim trunk reading a book and a woman in a swimsuit lying on a towel who is facing the sky with her arm over her face are on a white sandy beach together.
The couple was lying on the beach.
Mentioning a guy and a woman together implies they are a couple and they are together on a beach.
