She wore a simple white shirt with a blue bow tie at the neck, looking youthful and lively. Over it was a light gray knit vest with a diamond-shaped pattern. At the bottom was a short black pleated skirt, the hemline swaying gently as she walked.

She walked the campus avenue with her book in her arms, like the protagonist in a youth movie. Best picture quality, higher quality, high detail, ultra high resolution, 8k resolution, depth of field
