The captivating realistic cover of "My Dad’s Girlfriend Has A Daughter" features a close-up of a teenage girl with short black hair and an anxious expression, clutching a carton of milk in a brightly lit kitchen. In the background, a girl with long ginger hair smiles warmly, leaning casually against a counter near a stove with a pot of ramen. The kitchen is modern and tidy, with soft lighting and blurred details. The title, "My Dad’s Girlfriend Has A Daughter," is written in a casual, handwritten-style font, placed above the girls to convey a light-hearted yet intimate feel.
