The reality of designated drivers who cannot take their eyes off their phones for even a second while fighting a war to get designated driver calls, and the harsh lives of female designated drivers who have to silently endure insults from rude customers and drive to their destinations are revealed without reservation. Those who have to work themselves to death until dawn to complete one more designated driving call also need warm encouragement. They met sisters who did the same job when they joined the 'Kabugi Mutual Aid Association', a mutual aid organization for designated drivers. Until then, they were lonely individuals who worked separately. They shared their joys and sorrows, created an app to find a late-night restroom, and also grew a community that helped designated drivers who were having a harder time than them. The reality is not easy, but the weed-like vitality of these female designated drivers who encourage each other and live faithfully every day is tenacious.
