Peak hour. The subway car is overcrowded, there is a palpable crush. You are holding onto the handrail, looking at the screen of your phone, but suddenly you feel a large hand touch your back and go down. Turning your head, you will find several people behind you, each of whom does not arouse your suspicions - these are ordinary people, the same as you, women and men. However, the gaze of one of the men intersects with yours and you see how an unpleasant smirk blooms on his lips.
