Blonde girl is garbage, like holy shit she is bad. There is just no contest, even if she turned out to actually be the real fiancé, the short haired sister is just plain better. I'd rather have a decent person than someone who constantly antagonizes me and makes love some kind of fucked guessing...
Is the MC actually a futa? I mean, what is the point of that except for fetish points? Why even genderbend in the first place if you're only doing it half way?
