Can gender be optional? – Vampire Darling【Free romance game like manga】 Review

I LOVE the story line very much and the CG's are amazing but couldn't it be an option to be a boy or girl? I'd much rather be a tomboy on this, at least that what I try to picture in my head as I read it. I know you most likely don't check these reviews but if by chance, I'd be the happiest girl in the world if I could be a female in this, other wise, great story
