If she/he stays as a girl or turns back into a boy and ends up with the guy, wouldn't that make it BL/straight...? And if she/he stays as a girl and ends up with the other girl, then it would be GL/straight, I think. I also agree with the other comments here, I bet the FL/ML is going to end up with the guy, since it says "yaoi" in the title.
