Stories where the female lead is actually a declared bisexual OR it's not clear but there are established love interests of both genders
!! I didn't consider GLs, I have a dedicated list for those: https://www.mangago.me/home/mangalist/2794187/ (yes, just because the female lead ends up with a man doesn't mean she isn't bisexual, and same for a bi man who ends up with a woman. I don't know why it's so rare to see in fiction)
