Two girls play rock-paper-scissors, and the loser must wear a mouth gag and nose hook as a punishment game, gradually distorting their facial expressions. Their faces twist into awkward, uncomfortable grimaces, creating deeply humiliating scenes. The way their cute, innocent features become grotesque is a major point of fascination for viewers. They take turns losing the game, alternately forced to expose their gums and lick with their mouths pried open, intensifying the sense of shame. These shifting expressions and displays of embarrassment are key elements that enhance the appeal of this work.
