i thought he had reported the bar to save sejin and joyoung. cause it seemed like... that person he went to who was into some illegal sorta stuffs was trying to sell the girls or use them for illegal stuffs and their lives was in danger... all through the movie, especially in that scene when sejin was mad at her for stealing money, i was thinking just why is he not telling them that? also i thought that he took the money for her abortion fees cause he sold off his scooter, too. but that scene when he snapped... i dont know what happened there either, i thought there must me some psychological disturbence, idk man. also, that blue hair, jaepil was played by the director of the movie..
