Correct me if im wrong but I feel as if Jill and Isabella have the least amount of screen time after episode 7 as well as having the smallest impact on the story overall.
If you ignore Jill she's just some rich chick falling on a sword you hardly have to interact with. Compare that to the more elaborate plots with Sage, Josy, and Maya you're forced into that are 100% unavoidable.
Josy? Josy so far feels extremely shoehorned into everything, if you ask me. The only "plot" she really had was being the (non) GF back home of the MC while he was experiencing college. After that, she's pretty much tied to Maya in every single regard, except all the drama and character development is about Maya whiel Josy is like :l almost in every scene. I like Josy... but she's the character I'm the least interested in all of BADIK (or close to that) because she only works as a plot device to Maya drama and barely... barely anything else Her connection with Tommy? I dont think even Tommy *really* cares. I really wished DPC didnt shoehorned her into Maya as a couple and gave her a real purpose... and being a crying shoulder to Jill is not it, btw.
Everyone else's has a plot, I dont need to mention Quinn's, Sage is growing out her cheerleader who only dates douche chads "mean girl" persona out the window, Bella with her husband and her ice queen persona, Jill with her family, Maya with her father... Josy is the only one that is just... there...
