I only know only these 3 in my limited reading experience. May be others can mention more.
AHAHAHAAA (≧∀≦)
I don't think this would appeal too much to readers but I would want to read these kinds of stories ╮(￣▽￣)╭
I really hope this happens to Hisa-nii when he meets Mikado's oldest sister. I ship them already. (Yes Hisa-nii somehow is so feminine imo and Mikado's sis is the exact opposite)
I've mostly read gay female liking a guy instead, although still not many.

Kind of. The girl starts off liking girls, the boy liking boys, but in the end they end up w/ each other. They may have just been bi tho.
So I read hundreds of yaoi where the straight main guy turns gay because of this person he falls for.
Are there any shoujo/yaoi where the gay guy turns straight for this one girl??
Just curious ╮(￣▽￣)╭
