Suggestion: Railroad if a player isn't on all paths. If he is though make the harem official and make a scene with all. If you think one or more characters are not ready to participate sexually make them watch or exclude them. But have the initial conversation together.
If a player isn't on all routes he/she gets railroaded into a scene with one individual LI that they choose.
It's quite likely that the majority of playthroughs have all routes active in some form.
You can also make the outing conversation happen with just the girls that have a active route. But that may make more work because you have to make renders and dialogue for each config.
Playing Chapter 2 atm. Slight Critique:
*Slight Spoiler*
When Kaylee is asked to go with that woman the MC later says that he could be arrested if he didn't let her. Since Kaylee is an adult this isn't true unless he holds Kaylee against HER will. Calling the Police in this situation would've been totally in favor of the MC because the woman was also drunk which would result also the situation being in favor of the MC if the woman had a right to demand Kaylee to come for whatever reason because the MC could just say he protects her against drunk driving. That woman can't make Kaylee do anything she doesn't want to.
