Well, not all the time tbh, so going for a low love path for M+D will usually mean conversations don't go as deep and some of the nicer bonding moments are lost (but not lewds), and for the coven, acting like an asshole will eventually land you on their shitlist and they wash their hands of you.
But conversation choices weren't designed with the idea that saying whatever the other side wants to hear is the "best choice" and earns you lewd coins. They were written with the idea that you could voice your MC and have the other side react to that, and sometimes a little reluctance or disagreement isn't a bad thing, and earns you some respect or appreciation, or a funny bit of dialog. And even for choices that actually lose you love points, new points come often enough that if you feel a particular choice is what you prefer, you can easily stand the loss of a point.
My personal favorite path through the game is not so much "asshole MC" insofar as the game really allows for that (I have a hard time with VNs with douche MCs, and I can't really stomach writing one), but "reluctant MC", which means Denise starts doing even more of the legwork in conversations, convincing the MC that, "yes, trust me, this is a really good idea and you should totally let me."
