Upon some reflection, I've come to the conclusion that Bianca can easily end up in Jill's and MC's relationship. Out of every single character in the game, she is the only one that can easily end in such a scenario with the right choices.
Jillybean is a HUGE destiny stan. What is more destiny than Jill going to live in Lynette's old home thanks to one of her best friends mother's being Lynette's best friend? And then she fell in love with MC and then, her best friend ended up falling for him as well... and they both are not against going on each other as well.
This actually surprised me somewhat when I thought deeply about this. So maybe MaJo can end not being the only throuple and we can have another one coming soon. Not too early since for now, Bianca and MC only feel lust towards each other and a weird connection that draw them together... that connection being US, because we are a bunch horny fuckers.
