"Teacher, please stay with me just once?" When my student Nagisa confessed her feelings to me, I crossed the line and embraced her. How should I face school tomorrow? How should I treat her? I must think about Nagisa, my student. Even though I told myself that, I couldn't hide my ulterior motives from the forbidden young fruit that I had once possessed, and I repeatedly acted in a way that made me unfit to be a teacher. "Teacher, please stay with me after school today." Those pure words made me want to meet her again... I wish this moment could last forever.
