Anime Schoolgirl in Classroom

Anime-style illustration of a schoolgirl with dark hair in a ponytail and purple eyes, wearing a blue school uniform with a red ribbon. She is kneeling on the floor of a classroom, embracing someone's legs while looking up with a flushed, excited expression. The background shows classroom desks and chairs.

The image appears to be an original anime-style illustration signed with 'Oekaki Zuki' in the bottom right corner. There is no clear indication of the specific platform or original publication date.
