No rule breaking.

Firstly: Scarlet was a lesbian, you can't bring in a rule that wasn't there to start.
Secondly: It's cross-species where neither is human and both of them have different gene set-ups than the other. They're both considered female by their own species, so they take female human forms. They also are no longer in a relationship. They are literally only even able to be considered lesbians due to their cultures and preferred forms. 
And said cultures and genes I had planed to explain IC at some point after the other is introduced.
