The title is worded as such to avoid spoilers.
Is/Are Yuma and/or Hotaru actually exclusively homosexual instead of bisexual?
Or is this like left to the viewer/reader to guess or interpret or something?
I'm asking because I think it's usually the reverse like say
The Legend of Korra or Harley Quinn: Characters start out as seemingly exclusively heterosexual and then we find out they are bisexual. In Netsuzou Trap, I think it's the reverse: They start out seemingly bisexual, but it might turn out that they are actually exclusively homosexual.
But maybe that's common in yuri/yaoi where it's left to the viewer/reader? Or maybe the author has said something about this? Or re death of the author, maybe there's something in the story that tells us what his/her/their sexual orientation/s really is?
