Which one could be the most logical narrative arc DIK/CHIK of the MC?
I suppose the dev is trying to make sense of all the possible narrative arcs of the MC, and obviously there is not a "right way" of playing this game. The right way is the way every player enjoy the most. But there are narrative arcs that are more logical than others, IMO, given the initial premises of the plot.
The way I see it, the MC starts the game as a naïve, shy lad. He says that he's not shy, but the guy has a crush on Josie for two months and is not even capable of talking with her. She is the one who starts all the interactions and actively try to attract the MC. The MC just play along with her. He´s a CHIK at this point and make sense all his decisions are those of a CHIK and feels attracted by a girl that is not really mature, because he's not either. Josy doesn´t even know her sexual orientation and behaves like a whimsical girl, trying to charm the MC even if she's already in a relationship, like a little child calling dibs over all the cakes of a birthday party, even if he´s not going to be able to eat them all. First she attracts him, then she remembers she is a lesbian and into a relationship and tries to keep him away, then she tries to attract him again... The kind manipulation a CHIK MC would fall into.
The first days of college, make sense the MC being a CHIK too. He thinks he's not going to see Josy again, since she's leaving away, and starts thinking in Maya, that is like Josy, but blonde. She craves attention, is immature in his emotions, unable of putting her problems in context and prone to drama... and again as Josy, she tries to charm the CHIK MC, then remembers she´s a lesbian and has a girlfriend and tries to keep him away, then forgets about that and tres to attract him again... She even have sex (not penetration, but sex), with the CHIK MC. Again, it makes sense the MC continues being a CHIK, avoiding conflicts and feeling romantically attracted by the pair of immature girls, since he´s immature too and prone to fall into their manipulations. That's why he forgives Maya so easily after the incident with the taser.
A week pass, he goes to his date with Josy, and makes sense that he´s sincere about it with Maya, specially since he thinks that probably is a farewell date and he's not going to see Josy again. He has sex with her (why not? farewell sex) and after that, he centers himself in Maya. But he already has seen that life in college is not easy. He has been humiliated several times by Troy, the Joks, the DIKs and the HOTs, robbed, manipulated by Sage into helping her to spy her boyfriend... He begins to realize that the college is a jungle, and he can be prey or predator. So he starts slowly changing his personality. Make sense the MC starts adopting some DIK decisions after becoming a "maggot", specially since the tasks he has to accomplish can't be done by a shy guy. Performing those tasks he starts feeling more confident in himself.
Then, the "Hell Week" and the bomb of Maya and Josy being a couple and lying the MC about that. That's the inflection point in MC´s narrative arc. He realizes that playing along with Josy and Maya's whims and insecurities only harm him and from that moment make sense the MC starts adopting mostly (but not only) DIK decisions. He dives himself into the tasks of the "Hell Week" in order of forgetting his disappointment with Maya and Josy, and the most extreme tasks he's able to accomplish, the more confident he feels. Also, starts feeling attracted by girls and women more mature than Maya and Josy since he's more mature too: Sage, Jade, Cathy, Isabella, Jill and even Quinn (another different thing is if all those different girls are going to fall for the MC). He feels more confident in his own personal charm and ability to seduce women, since some of those women start to pay more and more attention to him. Last but not least, he stops avoiding conflicts by default because he feels more confident in his fighter skills too. That's the only way he can start being kind of a leader for the DIKs and take charge of the home repairing and assigning tasks to the other DIKs. I don't think makes any sense that a CHIK MC would gain the respect of the DIKs, a bunch of "alpha males", or at least, "wannabe alpha males". It seems that the game is drifting into a more "film noir" style, so in the future the MC will have to deal with more dangerous problems regarding the drugs and prostitution ring of Quinn. Again, I don't see a CHIK MC having the right stuff for that. When he says to Sage in the party of the "preps" somethin like that he has been so far an idiot playing along with other's orders and manipulations, it's the moment he fully wake up and becomes a mature guy, and the first thing he does is to take a step forward and go to deal with Cathy's problems, something other DIKs aren´t able to do. That moment he´s a leader already.
Lastly, it´s logical too the MC forgets his disappointment with Maya and Josy and forgives him, specially since Derek is his best friend. He's already in a different state of mind. I think that a CHIK MC would find more difficult to forgive Maya and Josy since his feelings would be more badly hurt and he would be less emotionally stable. A DIK MC would find more easy to move on. But also makes sense that he will maintain the distances with them and try not to be absorbed by their dramas again, since he's wiser now.
Again, I´m not saying this is the "correct way" of playing the game. The correct way of playing a game is enjoying it, and every player enjoy the way he wants. Just that this is the narrative arc that I see more logical among the possible ones given what we know about the MC and the things that happen with him regardless of the decisions we make as players, as joining the DIKs, being being fooled by Maya and Josy, becoming an informal leader of the DIKs in their worst moment, etc.
