Hi everyone, I know there's a couple of hostess guides already, but I don't like the idea of changing the looks of the girls. I prefer to keep their original beauty and be consistent with the event cutscenes.
So this guide will cover the way to get 3 double circles with everyone, using only the accesories.

Please, keep in mind that some accesories might not be available from the start and some might be a little expensive for the early game.
