Ever since losing my mother as a child, I struggled to make friends and lived a dull, lonely life. Then one day, Miss Momoko came to our class as a temporary teacher. Around my mother's age, she was a gentle and beautiful woman, though a bit timid and unsure of herself. To me, she quickly became someone special at school. Before I realized it, I found myself unconsciously watching her every move. A month later, I got caught up in an unexpected incident—one that would change my life forever.
