Mio, who commutes to school almost every day, becomes the target of a molester. She never imagined that the man's fingers, silently creeping up to her, would feel so good... To put it mildly, it's a perfect hit! Her mind knows she hates it, but her body wants it... While she can't make a sound, her love juices overflow and she can't believe how they are forming a string! What has been tied together is not the red thread of fate, but the thread of lewd love juice. Mio has become submissive and falls into an impure relationship, and today she boards the train where the man is waiting.
