No she doesn't.How? She always dumbs Sparkle.
She intitally rejects your proposition but by the end of the 0.4f update it was possible to be in a comitted relationship with her.
The thing to understand is that Roopah isn't going to outright say yes to your propositions but is slow to open up to you.
Start male go through the first act. Then select "Femboy" when given the chance and always sleep with Kayden. That's about as close to gay as you can get so far.Yes, you can play fully lesbian. I don't know why other people are telling you to be so careful. I've been easily able to stay away from all dicks in this VN. Just don't pick the obvious choices that would involve dicks. Trying not to spoil but, there are even a few situations where the story implies I'd have to make Sparkle suck a guy off or something to get what I want but I ended up having the outcome I wanted anyway without touching cocks.
I don't know if you can play as a gay man though...
