I've been following this discussion with great interest as I believe this game is one of the few if not the only one in this genera where you (mc) can actually grow some balls and divorce your cheating ho of a wife. So two thumbs up for that LadyLana.
That being said, I do believe there is a way for the Lady to write herself out of the "balcony scene corner". The NTR path can continue if MC wants to wait on confronting Julia until the divorce papers are drawn up and in her hands. The drawing up and delivery can take as long as LadyLana wishes. 2-4 weeks, 1-4 updates, whatever.
The point is that during this divorce paper draw up time, the MC will continually gaslight Julia into believing he is still her loving, completely-in-the-dark-about-the-cheating husband thus making Julia more comfortable with cheating and emboldening her to cheat more. I think this self corrupting cheating path Julia ventures down is something the NTR fans would like to see/watch.
I have no idea if LadyLana will go this route or how slutty she will write Julia on the cheat path, but what I do know is it'll be a hella good read because it has been so far and I have faith in her.
Anyway, take this grain of salt to go with these two pennies because this has been JUST an opinion.
