The captivating realistic cover of "My Dad's New Girlfriend" features a close-up of a teenage Asian girl with long black hair and a shy expression, clutching a worn book to her chest. She sits in a sunlit library corner, a melancholic smile on her lips, her gaze softly averted. The background is a blurred, warm-toned view of the library, filled with shelves of books and dappled sunlight, creating an atmosphere of quiet contemplation. The title, "My Dad's New Girlfriend," is elegantly displayed in a handwritten-style font, positioned above her head to convey emotional depth and the intimate nature of her story.
