The rhythm of horses' hooves clip-clopped along the road filled Joanna's ears.
Occasionally, the sound of flipped paper would be interfered with.
When it was perceived in Joanna's hearing sense, she would raise her eyes, removing her gaze from the page of the book that she was holding with one hand in front of her and covering the sight toward her face. Slightly lowering the book, she had her eyes fixed across from her.
That gesture alone had indicated that Joanna did not concentrate to read. If she did have ultimate focus on reading, as she usually did once the book was in her hands, most of the time she would not notice if there was a movement around her or she would notice, but it took some time before she realized that.
