A woman in all black throws a football indoors while man looks at his cellphone in the background.
Several people are playing inside the stadium.
One woman and one man do not imply that they are several people, nor does it imply that they are playing. Just because the woman is throwing the football inside, does not mean that it is an indoor stadium.
