Anime illustration of a girl with glasses, touching her lips with a pen in a thoughtful but mischievous expression at the same time, looking up, her head slightly tilted upwards as if searching for something on the ceiling, her hair tied back in an executive style, wearing only a white blouse, no jacket, with a close-up of her face from a side view. No deformed hands, no disproportionate arms, no multiple limbs, no extra fingers, no fused extremities, no misdirected heads, no misaligned eyes, no empty stares, no deformed eyes, no uneven pupils.
