Chapter 4 is the final chapter for each characters story, there will be more stories and characters outside of the main 3 romances though.
I’m not sure what you mean, each romance in the game has 3 chapters and a section in the introduction chapter planned.
So right now we have 2 chapters almost done for the 3 main romances. The other chapters will be other romances entirely, you will not be able to romance Marion/Grace/Jessie outside of the Marion/Grace/Jessie chapters. As for height growth, there is a couple things but they will not become giants or anything like that.
Not giants really I understand the misunderstanding there I mean like taller than Malcolm or maybe their chest get larger depending on their bodies before transformation. But again that's just my opinion. I really can see Jessie getting taller than Malcolm in some degree and Marion well I can her getting really big in chest area and I hope height but that's just cuz I like her the best so far. Im sorry if im asking or saying too much. Im fine with this novel I just think their should a bit of those growths slightly if a little for each one. But im really just hoping you guys consider it. And I hope im pestering too much with your great work. Also I wish you guys get success with these visual novels. I just really if not little in everyone then maybe one girl transforms to be way bigger than Malcolm but like 7ft or maybe 8 but not expecting the super big part since that's too much reworking and I want respect your guys work.
