Okay, question...
How big of a disaster am I going to be in if I go back to Zoey AND cheat with Bianca? Can I even do that??
Like holy shit Jill what am I doing with you 
I don't think you can actually do that.
That being said, Zoey hasn't really been a character I've gravitated towards so I wouldn't really care much about that. However, I'd love if Bella, Jill, and Bianca had a realization that they all were interested in doing naked activities with MC. That Sauna/Hot Tub event can be the catalyst to a beautiful relationship with them.
That way, we can treat Jill the way a princess deserves to be treated, give mommy Bella her needed attention and outlet (come on Bella, you know you liked that kiss with Jill deep down), and get freaky with Bianca (who deserves better than that boyfriend of hers who would dare look at another woman and even cheat... smh)
