It's a testament to the character writing that I went into this fully intending to play the dark paths and then had to start over after a while because I just felt bad and wanted to treat the girls well. Story and characters is usually window dressing to me in these types of games, but I don't think I'll be turning Kennedy into a drug addict even on subsequent playthroughs even if that means not seeing all the sex scenes.
The story definitely has some frustrating contrivances, but that's pretty unavoidable in these types of games, especially when there are so many branching options. Although some of these may be an issue of me trying to have my cake and eat it too regarding respecting the girls' consent when they are actually able to say 'no' while ignoring consent when they were unaware (sleep sex and pissing in drinks for example). A big one was Marshal anally raping Kennedy with Mandy during movie night. This was after I'd made sure to always respect her anytime she said 'no', so it was quite jarring.
Also, some of the dialogue doesn't make much sense if you're not participating in sharing content, but I suppose that's also unavoidable due to the nature of the game. Makes it feel less like I've turned sharing off and more like it's definitely going on and I'm just not seeing it.
On a completely different note, I was playing this while high and the scene where the interior of the van changes made me paranoid as shit lol.
