A young female stands in a classroom located in Panagyurishte, Bulgaria. She wears a black puffer jacket over a grey hooded sweatshirt and light blue denim jeans. Her brown hair is pulled into a high ponytail, with black sunglasses perched on top of her head. Her left hand, featuring long, light-colored manicured nails, covers the lower half of her face, while her right hand holds a light pink smartphone horizontally, oriented towards her. She appears to be looking downwards or to her right. In the background, classroom elements include light yellow walls, a whiteboard with a list of elemental symbols (Ca, Na, Mg, Al, Zn, Fe) above it, and a ceiling-mounted projector. Wooden desks and chairs are arranged throughout the room. A second individual is partially visible in the far-left background. The floor is a light brown color.
