I've never read any other manga with a couple like this, and I've read very few mangas that are so sensitive and nuanced in depicting gender and sexuality. Both lead characters are fully developed individuals, not cliches or tropes, with deep inner lives and complicated sexualities and gender identity. That's not to say that the smut isn't hot, but it's the beautiful exploration of both of their identities, separately and together, that makes this romance so sweet and compelling. Maybe my favourite manga in the whole world.The fact that they're first cousins doesn't bother me because first cousin marriage has been practiced all over the world in many cultures. But I kind of wish they weren't cousins just so more people would give this a chance.
