A young boy and girl are sitting in a bright, sunlit classroom with large windows. The boy has short, messy brown hair and wears a white button-up shirt with the sleeves rolled up, his blue tie slightly loosened. He leans back in his chair, arms stretched overhead as he yawns widely, his eyes half-closed. The girl beside him has shoulder-length black hair with a red hairclip and wears a navy blue sailor-style uniform. She sips from a tall glass of iced coffee, condensation dripping down the sides, her expression slightly amused as she watches the boy. Wooden desks are arranged in neat rows, sunlight casting warm streaks across the floor. A chalkboard with faintly visible equations stands at the front of the room, and a clock on the wall shows mid-afternoon. The atmosphere is relaxed, capturing a casual moment between classmates.
