Today I'm writing on the theme of "Omiya, soapland, petite faces."
I'll explain it by blending my own firsthand experience—over 20 years in fuzoku—with what I've picked up from research.
The basics
Let me lay out the fundamentals you should know about this area.
Watch this industry long enough and you'll see that even on the same topic, the "customer's view" and the "girl's view" can rate it completely differently.
What I can say from firsthand experience
I'll talk based on what I've actually been through myself.
I believe firsthand experience beats theory. This industry especially is a world where "reps" matter more than "knowledge."
Wrap-up and my 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 a shop I genuinely repeat. Take it as a reference.
