character: kotegawa_yui, A medium shot, eye-level anime illustration of Kotegawa Yui standing centrally in a bright school hallway. She is a teenage girl with long, straight brown hair tied with a neat bow, and expressive brown eyes, wearing a Sainan High School uniform consisting of a short-sleeved white shirt and a green pleated plaid skirt. She stands with a poised and disciplined posture, her hands clasped firmly in front of her, wearing a serious yet slightly flustered expression with a faint blush on her cheeks. The background features the polished floors and lockers of a clean, sunlit school corridor, with soft light filtering through distant windows. The visual style is a high-quality anime aesthetic with clean linework, a bright and airy color palette, and soft atmospheric lighting that creates a peaceful, academic mood.
