I play this game before at the start of the development but stop it, I went back to it now being a little wary of the Avoidable NTR and all but I think what really kind of put me off is this seem to be a GRIND and not so linear. Like a would like so to see it progress beyond the prom but it seems like you loop again a lot of times. How heavy is this on the Grind Aspect ?
I don't think it's heavy. The most grindy thing is building up the women's zeta stats, and once you get the hang of the game flow, it's a matter of holding down the Ctrl key until a decision point happens, making the right one, and holding down Ctrl again. (And maybe scrolling wheeling up if you notice a mistake just then.)
The main cycle* is seven days, each with a morning and evening event. If you're building up one woman, pick her every time. If there's any decision at all, pick the one that's nice to her. You can't decrease zeta even if you screw up. The worst you can do is have to do a run over again because you decreased her temporary stats too much and noticed too late to back up.
The most complex women to raise are Alexa (due to having sub and dom modes), Emily (due to having a lez mode that requires interaction with Alexa) and Sam (she and Emily have somewhat complicated decision trees). If it's too tedious for you to chart the effects, use the guide.
It occurs to me that if Llamamann wants to beef up the gameplay side in addition to the content, the decision trees for each of the women (eg the Hot Squad) makes the obvious sense to me. If it leads to more inter-woman interaction, that's icing on the cake.
*Hot take: SexBot is Llamamann's artsy fartsy interpretation of Robert Jordan
