it has only being that way cause the Mc was living /sharing the room with her but what will happen if the Mc move to the Dicks dorm we won't see the same interaction between Maya and the Mc like we're seeing right now the only time they will have to interact outside the studies are in parties or if the mc is having some kind of relationship with any of Hot's girls
Right now Jill is entirely irrelevant, you delete her from the game and nothing changes.
Sage is really important, since she adds confrontation between MC and Chad.
Josy is useless too, unless her bf is someone important in college.
Bella gave him clothes which helped him not get expelled, and she's hot as hell (no personal bias here).
Maya, as I said is the enabler of the story right now, everything important gravitates around her.
