A manufacturer received an email from a man! He asked us to investigate whether his girlfriend was cheating on him or not! So we asked a professional pick-up artist, a so-called "netori-ya," to help with the investigation! We asked him to pick up his girlfriend and monitor her with her boyfriend to see if she would actually cheat! We sneak into the cheating scene with a blindfolded play signal! The target is shaking her hips enthusiastically, unaware that her boyfriend is right in front of her! We remove the blindfold and face her boyfriend! The scene turns into a shocking scene!
