Incidentally, they look the same except for the glasses. She has a strong attachment to her glasses, and when other male students made fun of them, she got angry. She also mentioned that 80% of the reason she noticed Suzuki-kun during the school trip was because of his glasses, and without them, she couldn't recognize him.
