She was the only one in the bully group that was still kind to Lucy. She may not be comfortable with the bullying and doesn't want to shake up the dynamic as she would perhaps become a pariah herself. It's understandable. Not everyone is a maverick and self preservation is easy to sympathize with, especially in female circles which are socially quite vicious.
Basically you've made everyone feel sorry for Lucy to such a degree that they want her protected at all costs, and by an indirect extension, puts Hannah in a positive position because she showed kindness to her. Personally, I'm more interested in Sarah and the feminist girl. The slave play is excellent with Victoria, but she's too pure for anything truly depraved. I'd just feel bad. The woke girl on the otherhand is prime real estate.
I haven't posted yet but I might as well hijack this comment with my own feedback. I think your story is fantastic, dev. Your dialogue is on point and engaging. Pacing is good and I actually care about the characters, which indicates good character development and good writing.
My only complaint (because everything else is great so far) is the assets and renders. They're too vanilla. There are different shaders you can use to really make things pop, and plenty of custom assets made by users that you can check out. The discords are a good start. I'll admit, I honestly skipped over your game a few times because of this. It's not that vanilla renders are a problem in itself, it's just that most vanilla rendered Koikatsu or Honey Select games are very low effort all around and oftentimes not worth playing. I can see however that this absolutely isn't the case with your game. I'd recommend looking into shaders and getting the most out of your renders, especially since your game is in the early stages with not as much content.
Best of luck dev, keeping a close eye on this one.
