Oh, i put all my money in this.
I am sure you are aware of the similarities beetwen BADIK and AL. Well, who were the main girl in AL?. They are different stories, but every writer has his own obsesions, and one of the main obsession of DPC seems to be trouples.
And a really important piece of information, DPC girlfriend is... a feminist.
Now, thoose are hints, are meant to give a probable insight into the writer mind. But its story structure what gives you the confirmation. So let's see it.
But first, every conventional story (and this one it is) is the combination of a trouple relation Hero-Victim-Villain. It's the relation with the victim wich definesthe role of every character, thoose who help and thoose who hurt it.
Quinn is an interesting character for many reasons. But it's her relation with Maya who defines her role in the story. Her role was defined at the endig of episode 1/begining of ep2, when she "forced" Maya to grind herself with the MC and kidnapped him. Yet the scene (good one but ilogical for me) was explain by the same story as an agression towards Maya. Before that her character wasn't really defined, we almoast didnt knew her. Besides that, her relation with the MC depends on your path and the worst thing she did was to get Mona out of college. But when Mona get out of college? Exactly the moment that Maya was facing a similar scenario. Do you see? Is like when a movie they make an extra to have a horrible death in a moment when the main character is in a similar position, its not meant that we care about the extra but to build tension on the main character by showing what could happen to him. Even Quinn, Sage struggle (the other significant relationship that Quinn has with a LIs) has suddenly a name in ep7, and that name is Maya. Right now she is making Sage and Quinn to fight each other.
About Sage... yes she had her own story, but also Josy had their own. Now we know that was a sublot meant to build the main plot... her relation with Maya. Sage story is pretty simple, more than a story its a back story. At ep7 (when suddenly you can pursue her again) she had a complete swift. People were still arguing about the fundamental Sage traits, did she kenw about the buffet? Did she was therefore good? And at episode 7 she gets over Chad and throw herself into the Maya Quinn conflict, and by doing so defines her role, yes she is good, no she didnt knew about the buffet. And by doind it puts the whole Status Quo at risk. Again her role is defined at the ending of episode 7 in that speech wich is meant to be the core of the climatic moment of the whole episode.
About Bella and Jill. Well thoose are presisely the storylines who are not integrated yet to the main storyline. And yet, did you notice the intense way Bella looks at Maya? Yes, the simple explanation is that she is interested in the MC. But whythe story puts enfasis on that? Bella saw the MC with Josy but she didnt talk about her with Jill. She also saw him with Sage, but besides a couple of obvious questions nothing happened. And Bella-Sage relation is more significant. I call it a rushed foreshadowing and we will see exactly where it is going later.
All the LI's paths are going to converge as long as the history progress and by doing so become a single plot.
Finally, i give you the graphic show of the mainclimatic moments and endings. I think it is a good way to see the narrative structure:
