Seri, a member of the volleyball club, visits a sports chiropractor in front of the station with her mother’s introduction to relax the muscles she showed in her daily club activities. Seri receives the treatment in a jersey, but while being massaged, the hip joint is rotated in a piledriver or an m shape, and the practitioner’s hand creeps up on the genital area. In the meantime, palm sole pressure treatment to chestnuts and genitals began.
