Create an image of a couple where the man is noticeably older

Create an image of a couple where the man is noticeably older, around 60 years old, with gray hair and a kind expression, while his girlfriend is much younger, around 2, with long, dark hair. The couple should look happy and comfortable together, holding hands or walking side by side in a peaceful outdoor setting, such as a park or by the beach, with a warm, golden sunset in the background
