I dont know if this is ever mentioned or cleared up (I'm only mid(?) chapter 10) but, from Braden's thoughts and doubts regarding sexuality about himself--- I think he's definitely demisexual! Basically a label for those only able to have sexual attractions with someone that they feel deep connection to, no matter the gender. I've had the same doubts and feelings of guilt myself--- and scared also that people would think I was just "pretending," until I stumbled onto that term myself. It was so relieving to see I wasn't alone in that, and not only that, but the fact that it was called something. It felt more valid. I've never seen that portrayed in most media before, so it's nice to see it here, even if it's unintentional. That being said, being unlabled is so nice to be, too. Honestly, I prefer that. Sexuality, gender identity... I believe it's all too fluid anyway to have an exact label. We should just be living our lives the way that it makes us the happiest. <3
Heya :) so in terms of actual labels in the game, i've never officially confirmed anything. However, the demi-route you're discussing has been widely considered by a lot of readers. I have my own head canon but I never openly confirmed things just because i like to leave it up to the readers. your ability to relate to what you've read so far is a good example of why. if i confirmed something that was opposite to what you gained from it, I'd fear taking that from you and i dont want to take anything away from a readers ability to relate to a character or situation. so i've just decided not to do that. you're definitely allowed to put labels on the characters and there's definitely enough evidence in the story for you to draw that conclusion-- many have. So once again, you're not alone :)
