哆啦A梦漫画风格 - 十五轮

This is the teacher from Doraemon, male, about 35 - 45 years old. He wears a brown suit jacket, with a white shirt and a dark blue tie inside. Holding a blue - and - white alarm clock with yellow bells in his right hand, his mouth is wide open in a smile, looking excited as if emphasizing time in class. The background is a classroom, with green walls, windows, and papers with mottled handwriting on the wall.
