From what I understood, Swen mentioned that the issue with Gale was due to mistakenly setting his opinion bar thresholds too low. However, I'm not a fan of this gamified romance system where relationships seem to boil down to merely filling a friendship meter to access the hidden sex scene.
Ah, so it's the matter of the bar. then No wonder nothing's changed, at his "fixed" threshold he just becomes the same weirdo again.
