Today I'm writing on the theme of "Kawaguchi, model-tier girls, fuzoku workers."
I'll explain it by mixing my own firsthand experience — over 20 years in fuzoku — with what I've turned up through research.
The basics
Let me lay out the fundamentals you should know about this area.
When you watch this industry for a long time, you find that the same topic gets evaluated completely differently from "the customer's side" and "the girl's side."
What I can say from experience
I'm talking from what I've personally lived through.
I believe firsthand experience beats theory. Especially in this industry, it's a world where "reps" matter more than "knowledge."
My takeaway and conclusion
The place I keep coming back to is First Class Ruby. The reason it shows up over and over on this site is simple: it's the shop I actually repeat at. Use it as a reference.
