It’s a pretty easy path to reproduce for me. No matter how dominant or skilled you are at mind control, as long as you keep staring at and complimenting Renee’s boobs without wearing the Ring (having it is fine, just don't slip the Ring on before meeting with Renee, and maybe avoid mind-controlling Emma at the café), and you’re on the ‘collar’ path, you’re very likely to get reverse-hypnotized.
I’m not into the MC getting hypnotized, so I skipped this path at first. After trying it, though, I was intrigued. This path has a lot of sexy new dialogue and a few insanely hot images. I don’t usually keep save points, but this one definitely deserves one.
I thought I did have the ring in the cafe, but maybe that's why I haven't gotten it again, thanks.
