If you lived in conservative Asian country, you will know the difference. I have lived in probably one of biggest Asian city for half part of my life and then moved west. The first thing I noticed was difference in how cops and everyone treats female in West. In Asia, even a shopkeeper will talk over you to a man with when you are buying clothes for yourself. Let alone cops listening to your complaint. It is sad reality. Things are changing but not as fast as one wants
In those countries, there are no shelters to protect females during domestic violence and stalking cases. If she had parental support, she might have stayed with them and cops would have helped her if she got a supportive cop to take her case. Hiding from that clown is her primitive instinct for survival. None of the restaurant people helped her. How do you expect her to feel comfortable exposing herself.
WHY DIDN'T THEY CALL THE POLICE? WHY IS SHE JUST MOVING ON??? Don't get me wrong I like the story but this plot hole is so huge it will swallow all of Japan.
