A photo of a person who has become one-sided due to lounging on the couch would likely show a person laying on their side on the couch, with their body taking up most of the space on one side of the couch. they might have their legs stretched out or bent at the knees, and their upper body may be propped up on one elbow or lying flat on the couch cushions. they might be holding a phone or a book, or they might have their eyes closed as they relax. the person's face would likely be partially visible in the photo, and they might be wearing comfortable clothing such as sweatpants or pajamas. overall, the photo would depict a person who is relaxed and at ease, enjoying some leisure time on the couch.
