I have no problem with Shani being with other men, myself, and the devs have been pretty upfront about sharing content in this game and how it will always be player choice. For me, though, it just didn't seem likely that shortly after finally getting what she wanted with Z before she entered the zone, that she'd be in a big hurry to slut around. It just doesn't fit the rest of the story. Sure, she is a protagonist, but I think if she does anything, it would be more like using her feminine wiles as a distraction (as hinted by her trainer). Either way, whatever they decide, I'm on board with it as long as it make sense/fits the narrative so far.
