The mother, who visited the school for a three-way interview, enters the school restroom to calm down after having a bowel movement. But at the toilet, her son's bad friend was ambushed. Young men threaten her mother, who faints in agony because she cannot control her urge to urinate, and expose her. In addition, she began to gangbang her mother, who was upset by her leaking incontinence, as a meat urinal. Her mother says, "I will never forgive you guys...", but Ma Ko asks for her thick stick.
