Hoo boy, so this is one of those stories that I really wanted to like, since it had some interesting ideas, and its premise seems to promise some actual interrogation of gender and its norms, but... nope. That's not what I got. Instead we get the same old hackneyed gender stereotypes as we do in other stories, only even more weirdly articulated and squished in to fit the frame of a fake-deep story.
There's a really distinct lack of thought that went into the overall worldbuilding here that actually ticks me off more and more the longer I think about it. Like, why in the world do people still associate cuteness with women and coolness with men when the people in this society can, uh, choose their genders? Where did this gender stereotyping come from? And what about nonnormative sexualities? I wouldn't even be asking that question if the love interests in this one weren't so adamant about having the main character become a specific gender just to fall in love with them. (Jeez, talk about enormously bad gender politics. As any trans person would probably tell you, gender is a personal choice; it's about love of one's self, not love for another.) Like, the author makes some barebones attempts to critique this approach, but it feels overly clumsy, and really obvious that the author has never even spoken to a gender nonconforming person before, never mind cracked open a book even remotely related to gender studies.
Instead of an actual interesting story, this work is more like "rote teen love triangle" but with a slapdash premise of "oh yeah people can choose their genders" stuffed into it in an attempt to generate more drama. That premise honestly adds nothing to the story and is almost laughable with how throwaway it feels at times. Honestly, the more I think about it, the more I'm annoyed by it, not just from a gender perspective, but also from a storytelling one. If you're going to try and write something unique, at least actually attempt to make it matter. At this point, it's just a superfluous gimmick that's proving to be ultimately pointless to the overarching story. Hard pass.
