Starting the game from the beginning just for the fun of it. Have not decided the goals yet.
As many know, but it needs repeating, the Jill factor.
Bella said it best: She is naive. But really just unaware and never having had a proper boyfriend relationship.
MC is the first guy that was different in a good way and normal.
Time and again, early on, Jill believed Bella. That, MC was a good guy. Jill was convinced if Bella liked MC, MC was safe for Jill.
So, it makes perfect sense that with all that, Jill is unable to comprehend events when she sees MC and Bella making the beast with two backs.
Jill being unaware and unskilled about relationships means Bella and MC should have told her earlier.
I get it.
I don't like that it goofs up everything if you are on the Bella-only path but well, Bella and MC should have told Jill earlier.
