Taro happens to remember an old classmate of his named Wakabayashi Kiyomi who was teased back in grade school. He asks both his friend Saegusa and Reiko about her, but they don't remember much about her either. Then Reiko, who asks some of her other friends about her, finds out that Kiyomi led a pretty harsh life and that Taro, Saegusa and Reiko all played a part in that back in grade school. Meanwhile the gang begins to question Taro and Reiko's relationship.
