I wouldn't call it forced. Hints in the plot that you have to make a choice were in advance: for example, MC in Episode 7 if he is on several routes, including Jill, saying: "
What kind of piece of shit am I? I told Jill that I only need her and continue to have fun with Sage." From those examples that I remember.
DPC planned to create a story with different brunches, and he separated them, writing in the plot that girls began to communicate with each other.
And in the end, it's Maya's fault, because she infects other storylines like herpes with her student loan.

Indeed Sage with her kinky personality and M/J is a good choice for a player who is interested in polyamory.
But for me "Others" is the best for it. Get out of the relationship and have a fun student experience.

Fuck anything that moves. For now.
