It will depend the MC' choices.
The main plot is the MC rebuilding his marriage.
After that, some actions of MC will lead to cheating path or sharing path.
Hi.
Cheating/sharing content will be available only for Grace.
Lolly is a sweet girl and most of the time will be innocent. The standard girlfriend.
So in this case, I don't think she will get involved in such kind of sexual activity.
At least not so easy. To achieve something like this, the MC needs to put lots of effort to open her mind.
Well, when following Grace or Lolly path, a different line of events will happen.
The only link is the MC.
For this next version, only if going for Grace path the MC will face someone that can make it happen.
Grace is not like Eleanor from lop.
She is the typical married woman, with moderated behavior.
The MC acts like the trigger for her future actions.
