So ... I don't get it.
Both girls are shown to be ok with open relationship, and player is led to believe they get closer to one another, only for Mal to reject it despite all that setup? I mean, I could see it if they find out MC is also with other girls (Amanda, Lisa, Bianca, Tanaka, Erica or Linda, etc.), but if MC were faithful to Jaye and Mal it seems weird to discount that outcome as a possibility.
What is the point of the opening sequence teasing in this update, and of Mallory previously inviting Amanda for a threesome, etc. if she just walks away?
Opening a throuple by committing to Jaye would mean missing so many intimate moments with Mal that it makes even less sense to give her a backdoor into the relationship at the end.
