Who are you?

A man with short brown hair, wearing a blue shirt and dark vest, speaks with an intense expression to a woman with dark hair and a black top with brown straps, who looks at him with wide eyes and a slightly open mouth; the scene takes place in a dimly lit room with greenish lighting, bookshelves, and a lamp in the background, and the man's mouth moves as he speaks while the woman maintains her gaze and expression.
