He cannot bear the thought of exposing her naked body in public, so he makes the disastrous choice of consulting his boss, Oshima. Oshima comes to their home that very day, talks the couple into his plan, and even schedules the shoot that will capture Reika’s shocking descent into humiliation and infidelity.
