A couple of people have entered the frame, one apparently from each side going toward the other side. They don’t seem to know each other as there is no hint of recognition, and they appear to be making (appropriate) way for the other.
Person entering from the left is a young adult female; she’s apparently jogging judging by the clothes she is wearing and the manner and pose in which she is drawn. Judging by the manner and pose she is doing so rather leisurely, in no hurry.
Person entering from the right is a young adult male; he seems ready to flash a smile in the jogger’s direction.
