地味な幼馴染

anime illustration, great quality, best quality. In a medium shot from a slight low angle, a high school girl with glasses sits at a wooden desk in a sunlit morning classroom, diligently writing notes with a pencil in her right hand while her left hand steadies the notebook, her focused expression showing concentration with furrowed brows and pursed lips. She wears a navy blue blazer uniform with a white collared shirt, red tie, pleated skirt, and knee-high socks; her long dark hair is neatly tied in a ponytail. The organized desk holds stacked textbooks, an open notebook with handwritten notes, and a blue pencil case. In the background, a large blackboard covered in chalk equations and diagrams stretches across the wall, with soft warm sunlight streaming through large windows on the right, casting golden rays and gentle shadows across the wooden floor and empty desks, creating a serene and studious morning atmosphere with subtle depth of field blurring the distant elements.
