Will the lesbian be optional?
Oh wow, someone asked the same question too, I hope that you don't mind me copying and quick-editing my answer
For now, I don't think that I will have a full-blown lesbian/bi route in the story because it's just out of place, plus, it's not something that I have experiences to develop ideas on.
Also, if I were to include it (again, this is a
big "if") - lesbian, to me here, is just some actions during the group sex. Even with this, I still haven't planned this far yet. But again, I will never force people into a kink that they don't want to do.
Hope that helps!
TL;DR: No lesbian content is planned for now, and if Cyberheart had lesbian content, it would be 1) optional, and 2) not be a full-blown lesbian lovers route (just some actions between the girls with MC involved also, in the umbrella of MFF tag).
