A whimsical and expressive lofi doodle of a girl in a purple-toned classroom. She is sitting at her desk, wearing headphones and intently studying with a pencil in hand. Her desk is adorned with various stationery items and a cup of coffee. The room is filled with natural light from the window to her side, and the view outside is a serene cityscape. The art style is a mix of free-handed line art and basic shapes, creating a calm and inviting atmosphere.
