Honestly I like to joke about but there is not way is MMF threesome, I believe that will be option way in the future(for my part my MC will never share Lacey) but if we take ACT2 in consideration only a MFF can be the valid option.
I think the fuck up will be something different, I hope it is not something that will hinder her wonderful growth, and I personally would like if it went back to a hinted but never explored thing such as the graveyard humor or something from her past.
I fear, to my utmost chagrin, that it will be the fucking pimp instead.
Yes, both were failures and Lacey is still convinced that her "Love Experiment" is the best way forward.
You know, it is weird sometimes, but I can understand her somewhat.
She did have some great ideas at the beginning as the "love experiment" was not the main thing:
L "I want to do other things you've missed out on too."
L "I want us to have more parties."
L "I want to expand our circle of friends."
L "If there's something you've always wanted to do or try, then we should do that."
L "Maybe we could travel."
L "Or maybe we could find a hobby we can do together."
Which would mean to create new experiences for both of them, something they can bond over aside from her utter betrayal and the pain she caused.
MC had a great line which is very true (and it is proven by studies):
"There's no such thing as special."
"When you're with someone who's done everything with everyone."
"Nothing is really special."
MC and Lacey have literally nothing that is just "theirs", not even the phatomed kiss is theirs anymore, and one could argue that her love for him is unique and special, but it is impossible to see or to feel, for the simple fact that in the eyes of MC it has been betrayed over and over.
So yes, MC should explore the world without her, create his own identity outside of his doormat one, and maybe find also that he can be appreciated by others (this is a bit of an issue because EVERYONE loves him and even the most dense or damaged person would see that).
They should also try to create some good memories that are only theirs as I said, this is why the "group trip" to vegas was a bit of a letdown because it goes against this very good idea that Lacey had (for once

).
So Lacey was not wrong in act 1, in act 2 the whole "fuck around and be happy" part takes over completely in the writing.
I hope it ends up being better than I think it will be. From the update, I can even see how it could be FFM with Lacey making it like the KW where all the focus is on the MC. I can see where that can be considered gentle and Pro MC and could go wrong with Lacey getting jealous.
The problem with the KW is that it was never about MC, not once, and I STUDIED it.
He gets belittled often, he never makes a single choice (maybe one if you count who he choses to sleep with, but even that is dictated by Lacey), never makes a request or a choice.
The pace is dictated by Mia and Lacey too.
However, I'm not sure why if it was that easy of a scene Prof would point out in the update that it will be avoidable.
Is there anyone here that would even consider avoiding the content if it's FFM? I don't think it would even be worth pointing out in the update that it is avoidable if it's FFM.
You'd be surprised, some people are against any sort of sharing, even if it is MFF.
But yes, why point it out if it is not MMF, if it was with one of "his" girls, the writing was on the wall since quite some time so...
I think it will be MMF. It will look like another train wreck about to happen. And then maybe it won't be bad. Maybe the one sided is between Lacey and MC. Maybe this is why Prof said it will be avoidable, but you don't want to skip it.
The Prof painted the JD as an emotional growth and "good" moment, so this is probably his world view (my own speculation totally I have no idea what he thinks or not) is quite different in that regard.
Lopsided could be that MC is the center of attention, which for many would not be enough to justify another cuck scene.
But let's see, these 3 weeks can't go fast enough.
