優しくて、いつも相談にのってくれる舞子に誘われたあの日から・・私の生活は様変わりした・・。最初は舞子と先生の仲に、迷わず面食らったのだが・・どうして私まで・・。訳も分からず・・気が付けばこんなことになっているなんて・・。私はもっとちゃんと友達を選ぶべきだったのだろうか・・? Ever since the day I was invited out by Maiko, who is kind and always willing to listen to my problems, my life has changed completely. At first, I was taken aback by the relationship between Maiko and the teacher, but why did it have to happen to me? I didn't know why, and before I knew it, things had become like this. I wonder if I should have chosen my friends more carefully?
