Big brother

A blonde anime girl with blue eyes and a blue butterfly hair accessory displays a sequence of facial expressions, starting with a wide, joyful smile, transitioning to a calm, closed-eyed smile, then opening her eyes with a neutral expression, followed by a look of surprise with widened eyes and an open mouth, and finally a shocked expression with her mouth agape. She is in a close-up shot against a plain, warm-toned background.
