The Presenter in the Lecture Hall

A girl with black bobbed hair and a white hairpin stands before the lecture hall chalkboard, holding a tablet while giving a presentation in her white lab coat. Her dark eyes carry a slightly surprised expression that conveys the tension of presenting, while the white coat over her black turtleneck gives her a researcher's appearance. Graphs and equations are written on the chalkboard behind her, and empty chairs create the atmosphere of a lecture hall.
