i agree mostly but i also do understand why nao called yuma straight at that point, because this is a guy who just got out of a straight relationship and has never had any experience with queer relationships at all + nao just having been cheated on by someone who left him for a woman. at that point in the story also, it was implied that yuma only thought to say “yes” because he overheard nao saying that he didn’t want to date men that weren’t explicitly gay.
it’s kinda complicated bc to me, yuma isn’t really straight bc he’s already slowly coming to terms with his feelings (at that time) and they already had sex, but i really do understand nao’s feelings of being scared of being another “experiment”
it’s undeniably true that nao’s ex is just a piece of shit, straight or not.

This kind of story seriously needed more time. The uke seemed to have some really harmful thoughts about bi people and the seme clearly didn't understand much about queer people in general. The uke still calling the seme straight even after he DIRECTLY asked him if he was gay and was told "yes" was really irritating. I could go on a whole tangent about the smaller stuff too. None of this stuff is bad on its own I just wouldn't really liked it to be longer and fit some of the plot points to be fleshed out. It's a shame because this story had a lot of potential
