Agreed. And with the way the characters are set up, it'd be virtually impossible for some to have shared paths.
Charlotte, for example, would never be able to be written in a way in which she'd share you if on her path. And to rewrite her to where she would, would invalidate the entire game to that point. It takes her what... 14 chapters before she openly admits to being interested in the MC, and the best we've done so far is massage her feet and cuddle in the limo. But wow, I think she has the right kind of possessiveness in her, if you are on her path and when the three run into Fox.
Same with Lucy, I don't get the vibes from her that she'd want to "lose out" on the MC deep down. She's always lost out to Charlotte and everyone else around her, but I could be wrong.
Emma's LI path, I also don't really see a believable way to write her where she'd be happy to have you galivanting around.
I do hope that Kaylah gets a path, as she's a fantastic well done character. Naive to the modeling world but not as frustratingly naive, at times, as Emma. I don't anticipate there will, but it'd be a great way to move into a sequel now that the MC is going in fully aware of what Hillside is really like.
Just my two cents.
