The wrong choice discussion has to do w/ the Nameless event. I think one choice impacts whether or not you can simp for him or something like that. If you pick the wrong choice, it's difficult to reverse.
Yeah, they haven't added those kinds of scenes w/ Roushk yet besides a quick bj during the hunting contest and watching fireworks w/ him.
Resetting your save file won't alter that. The big thing people are noting about the Nameless event is that one of the times he asks you a question, that question becomes locked to your computer and cannot be altered.
So there's no need to reset your save file for anything (In fact that literally /won't/ do anything, haha), just whenever he asks you a question make sure you select the response you mean to select the first time, rather than expecting to be able to reload back and tweak things.
