Several hours later, he is somehow released and goes to his office. However, everybody knows what's happened to him and he finally gets fired.... When he is at a loss what to do on the street, an old man taps his shoulder and tells him that it was him who did train molestation on the train. He gets mad at first, but he soon realizes blaming him makes no difference. The man says, "I'm really sorry. However, why don't you take revenge on them...?" When he hears it, something flashes inside his head....
