Yume Ayakawa (25) experiences a disturbing incident on a train. Despite the presence of other passengers, a man aggressively assaults her, completely disregarding the public setting. Witnesses claim the man acted bizarrely, and when others attempted to intervene, he instead pulled out a smartphone and began recording. Rumors have spread that the man applied an unknown substance to the woman's genital area. His bold, unapologetic behavior led some passengers to mistakenly believe they were caught in the middle of an AV shoot.
