Do not disagree there but a small scene giving some hope with Lexi would not be amiss after that end and possibly Nikki/Cara as well for those on their path. From the moment they put MC on the spot without asking him how he felt about that and made MC choose after knowingly both playing with his feelings. Both have been neither for me, which is still possible by avoiding them both as LI.
Erynn, well I guess we get one or two more tidbits to worry us even more. With game halfway I do not think it is time for major reveals yet on her path and I think Lexi will play a role there as well and likely a few other things need to be setup and in place, since that will likely be the last to complete unless there will be an incest route which most of us do not expect to be there in the first place.
Erynn is a difficult one, if you keep pushing her back, you are gonna end up with more people commiting to other routes and maybe make the most interesting storyline (imo), the one that could hold a game all by itself, rushed near the end.
Maybe revealing it now won't be so bad, giving enough time for, disbelief>rage>acceptance/reunion>problem solving>happy ending.
One thing i mentioned but didn't expand was the possibility of flipping the usual order, give a happy romantic scene before revealing the problem... it's unusual, but it can enhance the drama even.
A happy romance scene (besides curing Erynn fans blue balls
Now, against her better judgement she doesn't tell her big secret right away, she just wants to enjoy the happy moment and keep it going... but then we learn the secret by other means (Ethan being a dick or getting access to that VIP room) and it's that much more shocking and dramatic than if she just comes by and says "this is what i actually do".
For Alexis+Erynn, i'm sure both paths will include making them friends again, just can't leave it like that.
