I'll just close my point of view on the Sage/Jill choice with this.
It's my own opinion to think that choosing to Help Sage in need shouldn't have stop me to have Jill as Love Interest, to stop me from having that choice without knowing it, since we do have to make choice later in episode 8 with which Li we want to be, i should've had the possibility to have that choice for myself like in ActingLessons (Game that i love very much by the way).
I know some of you don't see it that way and i respect your view and opinion, but that's how i see it for myself, the dev didn't have to write a part that excluded one or the other girl since he wrote a part where you have to make a choice between multiple LI to become a possible girlfriend and by definition, exclude all the other girls except the one your heart choose.
