(the list is mixed but you can tell from the cover if the story is about has endgame straight couple. Same for the type of media, just check the art style title name and gente to see if they're manhwas).
There aren't much... One of the couple being bi is more common in BL and GL... Sorry I cant rec straight ones, I didn't many of them.
That's fine! There are probably not many of them anyways. Thank you <3
The only one I can think of where the ML bisexual and it’s not a BL is Paradise Kiss.
I just realized I have never seen any bisexual man/woman in "straight" romance manhwas. We can see it in BL/GL manhwas as the man having an ex gf while currently dating a man or the woman having an ex bf while currently dating a woman. But what about in man x woman relationships? I want to read a "straight " story with bisexual characters. Anyone got recommendations?
