A medium close-up, slightly high-angle shot of a mature, sexy JK-style girl with long black hair in a side ponytail and blue eyes, taking a selfie with a pink smartphone held in her right hand, her left hand making a peace sign near her face. She has a flushed, blushing expression and is smiling sweetly at the camera. She wears a black western-style school uniform jacket with white trim and a pink inner lining, an open white shirt, a burgundy bowtie, a white plaid pleated miniskirt, and black thigh-high socks. A blue sports bag is slung diagonally across her body. Floating heart particle effects surround her. In the background, a blurred wooden basketball court floor, glass windows, and a distant basketball indicate a sports training camp setting. Speech bubbles contain Chinese text: "Hehe! Day one of the training camp!", "One week left", "Be good", and "Miss me?". Clean line art, anime illustration style, bright and vibrant lighting, sweet and affectionate atmosphere, high quality, best quality.
