I don't haunt that thread. It was not answered in the 20 or so posts I checked and the search function, which I used, gave dozens of replies hailing back to 2018.
So... not my fault.
That said and in the absence of a walkthrough:
Are there any crucial decisions in the update that are not kinda obvious? From what I've played I have tried some of the "not clear what the result is" answers and all branches end up in the same situation more or less with differences in the dialogue and the stats. I.e. whether you invite Bella or not, she shows up. Etc.
Look, my post was in jest to Avaron's.
I actually do not care about the WT, but I will say In this game, I have not really seen the need for a walkthrough in terms of relationship status. The only one that was a bit tricky IMO was Wanda. You had to treat her like shit.
All the other ones is pretty self explanatory With hints in the actual options to tell you the consequences of your choices.
Yes you might miss a scene here or there, but nothing that locks you out of a girl. Then there is always rollback and the stats at the end is a dead giveaway in how you did with all the girls. Also all the girls if you talk to them instantly gives you feedback in terms of facial expressions. The bigger the smile, the more positive they perceive your choice. The game also give you various chances to break it of with them or to re-commit your relationship status.
So if you want to chase after one girl, just don't be a douche. I guess at some stage conflict is going to occur, but I don't think a walkthrough is going to help with that. You are going to need to start choosing between the girls.
