"A stunning anime-style cover art featuring Luna, a 13-year-old girl with caramel skin, expressive large eyes, and flowing curly hair. She is shy but determined, wearing a cute, stylish outfit that reflects her personality--perhaps a pastel-colored dress with subtle floral patterns. Luna stands in a charming, scenic background of a blooming park in spring, with cherry blossoms floating around. Her posture is slightly hesitant yet hopeful, with a soft blush on her cheeks as she clutches a small notebook to her chest. The art should be vibrant and heartwarming, capturing the essence of young love and the whimsical charm of 'Head Over Heels.' Include a gentle, dreamy atmosphere with warm lighting and soft, detailed lines."
