Much of that inconsistency is due to the structure of the AVN medium and the fact that players can choose both DIK and CHIK options within the same playthrough. To minimize the inconsistency, DPC has implemented the status and affinity concepts that make some choices unavoidable or block out some choices. So, for example, the MC can ask to "just be friends" with Maya and Josy or he can ask for something more. And perhaps the reason that he resists having sex with Sage after the workout is because he doesn't want to get hurt by Sage the way he did with the Josy/Maya situation. Even if a typical 18/19 year old boy were a 100% emotionally and mentally consistent person, if DPC created a character with total consistency, I think it would be difficult to offer players any real choices. At best, those choices would be very limited. Is it "realistic?" I suppose not, but very little in any of these games is what I'd call realistic. I knew a guy in college who got laid a lot and while it appeared relatively effortless to me, even he wasn't juggling the constant pussy that our MC is getting, even on the CHIK path, and he's only been on campus for several weeks.
The reasons must be given to me by history, not by me.
then I don't understand what you wanted to say about the question of friends only
a DIK MC will be rejected, so the friends-only option is theoretically for him... can you imagine? the dionysian MC would be the one who, after a day spent in hiding (even if he was the most DIK among the DIKs), magnanimously decides to let them go their own way. come on... and he is forced to accept it even after being rejected....
the scene is not very well constructed, but the option to remain friends, at that moment, simply doesn't make sense (then so incidentally, how does Josy reward this magnanimity? by throwing in his face that he should have fought for her... great, great friend)
so the only one who would make sense for her to ask him for his friendship is the MC who might have them... he has to self-punish, voluntarily
if the whole thing had ended with a generic forgiveness, without embers and hugs and if anything with a little 'anger would have been 100 times more credible
is there a single clue that makes us think MC is afraid of being hurt by Sage? on one occasion he can point out that he really cares about her (not just sex) and she shuts him up, an optional step, punished by a loss of RP, otherwise absolutely no sign. to make it even worse is that it's a completely unnecessary twist, at the end of the episode they're pretty much fuckbuddy again.
there are some nonsense that arise from our choices, it is not the best that the story does not take them into account, but let's say it is a limit of the medium, but those I am talking about are topical moments of the universal story (the discriminating factor for Sage and Bella is to care about them, or rather for Bella it is to thank her)
of course the story is not realistic, in fact we were talking exclusively about MC's behavior
