A digital illustration of a teenage boy sitting happily at a desk in a bright, modern classroom. He is wearing his iconic blue jacket over a beige shirt and beige pants, with a relaxed smile on his face as he listens to the lesson. Around him, a mix of boys and girls are sitting at their desks, chatting quietly or paying attention to the front of the room, creating a lively and natural atmosphere. The classroom features large windows letting in soft morning light, posters or educational materials on the walls, and neat rows of desks. The illustration is vivid, clean, and highly detailed, with warm lighting and a positive atmosphere, consistent with previous character designs and illustration styles. --cref <https://s.mj.run/yRe3P-1UY1I> --chaos 10 --ar 16:9
